# Documentation

FIFA Connect ID .NET SDK, v6.1

# 1. Introduction

Main responsibility of FIFA Connect ID Service (FCI) is to generate a unique FIFA_ID for a football/futsal/beach soccer stakeholder. Football Management Systems operating in different Member Associations integrate with the FCI in order to register persons, organisations and facilities, and have FIFA_ID generated for these entities. Integration can be done in two ways:

- directly - by using REST API of FCI

- [recommended] via SDK, a library which wraps REST API and simplifies access to the service

This documentation is a reference point for a developer who wants to use SDK to integrate Football Management System with FCI.

Documentation is organised into three main chapters which discuss all aspects of a certain entity type management.

- Chapter 3 - describes how to register, update or merge the Person. A lot of attention is paid to finding national and international duplicates for a person being registered.
- Chapter 4 - discusses all aspects of Organisation registration, update and merge
- Chapter 5 - shows how to register or update a Facility

Chapters 2 and 6 provide - respectively - a brief introduction to setting up the integration and an overview of latest changes to SDK.

## 1.1 Clarification on the class names

Class names – although sometimes confusing – follow the FIFA Data Standard and as such they cannot be subject of modification.

## 1.2 Unexpected Setters

Some SDK classes that represent read-only data provided by the server side (e.g. `PersonDuplicateType`) contain setter methods. This data isn’t normally modified on the client side. The reason to have them, however, is that the client can easily simulate possible response from service by setting values to objects – and that can be useful for testing.

## 1.3 Date and time

All SDK methods require date and time in the UTC time zone. If date/time is passed as an argument to the SDK method and is not in UTC then Exception is thrown.

Note: pay special attention to birth dates so that they are not affected by time zones changes. For example, both persons born in Chile and Japan on 1.1.2012 should be registered as born on 1.1.2012 0:00 UTC. Consequently, all birth dates returned from the SDK should represent a date without a time zone (time zone should be disregarded when comparing dates). For example, birth date 1.1.2012 0:00 [UTC-3] represents the same birth date as 1.1.2012 0:00 [UTC+9].

## 1.4 Thread-safety

Any instance members are not guaranteed to be thread safe. In particular all methods on `FifaConnectServiceBusClient` cannot be called from multiple threads simultaneously. If needed, new instance of `FifaConnectServiceBusClient` should be created per thread.

# 2. Setup

## 2.1 .NET version

The SDK is compatible with .NET Standard 2.0.

## 2.2 Installation

The SDK NuGet has to be installed in your project. Refer to the instructions for how to do that.

## 2.3 Logger implementation

Each SDK client method uses an instance `Fifa.ConnectServiceBus.Sdk.Logging.ILogger` in order to log any errors that might happen during the application runtime. There is no default Logger implementation provided, as different parties could want a different way of storing logs. Implementation of such Logger class is required during instantiating `FifaConnectIdClient` or `RegistrationFacade` classes.

A frequent mistake when implementing the `ILogger` is ignoring the `args` parameter when formating the message.

Example of the `void Debug(string message, params object[] args)` might be:

    Console.WriteLine(string.Format(message, args));

There are methods accepting Exception object as the first argument. Please make sure to handle it properly, i.e. include the inner exceptions (if any) and the stack trace. The message itself might not be enough.

## 2.4 Validation against the XSD schema

The SDK validates input against the XSD schema you can find in the `Resources` directory in the SDK package. By default, the SDK assumes that the `Resources` directory is located next to the executing assembly (typically in `bin/Debug/` or `bin/Release`). If the SDK fails to locate it, it won't be able to validate anything because the construction of FifaConnectIdClient will fail with an error message indicating that the file `scenarios.xsd` could not be found. However, there is a way to tell the SDK to look for XSD files in a different location. You can instantiate `XsdSchemasDirectoryResolver` using a constructor accepting an argument pointing to a directory where `scenarios.xsd` is located, or implement your own `IDirectoryResolver`. The resolver then needs to be passed into constructors of classes requiring it as the last parameter; for example:

    // serviceBusClient, logger, responseAwaiterFactory, responsesCache, personLocalSender, personLocalMessageHandler creation is explained in next chapters

    var xsdFilesResolver = new XsdSchemasDirectoryResolver(@"C:\custom\directory\where\scenarios.xsd\is\located");

    TmsFacade tmsFacade = new TmsFacade(serviceBusClient, logger, responseAwaiterFactory, responsesCache, xsdFilesResolver);

For `RegistrationFacade` it needs to be passed as a property of `RegistrationFacadeSettings`:

    // environment, clientCredentials, privateKeyStorage creation is explained in next chapters

    var settings = new RegistrationFacadeSettings()
    {
        XsdFilesDirectoryResolver = new XsdSchemasDirectoryResolver(@"C:\custom\directory\where\scenarios.xsd\is\located")
    };

    var facade = new RegistrationFacade(environment, clientCredentials, privateKeyStorage, logger, settings);

# 3. Person

Current version of the SDK supports two approaches to operations on Person entity:

- using Registration Facade to register/update/find a person and search for duplicates at the same time. Due to personal data protection regulation, providing details of persons from other MAs requires communication with Hashing Service and Connect Service Bus. Registration Facade hides this complexity behind a single method.
- using FIFA Connect ID Client for other scenarios (including force registration or registrations management).

Two following sections describe implementation steps which are necessary to cover both scenarios:

- Chapter 3.1 - Person registration/update/search together with a duplicate check
- Chapter 3.2 - operations on Person entity not requiring a duplicate check

Note that in most cases you would need to use Registration Facade instance, not the client. It is, however possible to get FIFA Connect ID Client out of facade as shown in below example.

    var client = facade.ConnectIdClient;

## 3.1 Using Registration Facade

The `RegistrationFacade` class simplifies the usage of `FifaConnectIdClient` and `FifaConnectServiceBusClient`, in order to cover full scenario of registering a person in FIFA Connect ID. If potential duplicates are found, Registration Facade will send requests for person details to other MAs using Connect Service Bus and wait for their response (with timeout). The same logic needs to apply when one tries to update Person details or search for duplicates but does not intend to register a person even if no duplicates are found.

### 3.1.1 (Step 1) Get FIFA identifier of your organisation and client credentials

In order to start registering entities (persons, facilities, organisations), you will need a FIFA identifier of your organisation (i.e. MA), a set of client credentials (to authorize your instance of SDK with Connect Id services) and a pair of public and private certificates generated (so SDK could encrypt and decrypt outgoing and incoming data).

Instruction of how to generate and upload certificate can be found in `fifa-connectservicebus-certificates-generation.html`. After it's done, a next step is to provide generated private key to the client. The easiest way of doing that is to use `PrivateKeyMemoryStorage` class. In order to create its instance, you need to provide `X509Certificate2` object(s) as its constructor parameter(s). Each `X509Certificate2` object consists of the key (from generated file) and password (optionally). Please take a look at the following example:

    var pathToCertificate = @"C:\Encrypt\certificate.pfx";
    var certificate = new X509Certificate2();
    certificate.Import(pathToCertificate, "password", X509KeyStorageFlags.DefaultKeySet);

    var privateStore = new PrivateKeyMemoryStorage(certificate);

Note that in above example we used `PrivateKeyMemoryStorage` class, which implements `IPrivateKeyStorage` interface. In fact, any implementation of `IPrivateKeyStorage` could be used here - we don't restrict using own code at this point.

### 3.1.2 (Step 2) Create Registration Facade

Then create `RegistrationFacade` object:

    var environment = ConnectIdEnvironment.Beta;
    var clientCredentials = new ClientCredentials("clientId", "secretKey");
    var privateKeyStorage = new YourPrivateKeyStorage();
    var logger = new YourOwnLogger();

    var facade = new RegistrationFacade(environment, clientCredentials, privateKeyStorage, logger);

More about logging can be found here 2.3 Logger implementation.

### 3.1.3 (Step 3) Setup Service Bus listener

After creating facade, you can set up the background listener, which will listen and process new messages received from Connect Service Bus. This is the key element that every MA needs to implement. It allows all MAs to exchange persons’ details from their local systems via Service Bus in order to catch international duplicates and ensure that the same person will not be registered twice.

When `RegistrationFacade` and listener are running under the same application SDK uses `PersonDetailsMemoryCache`. This default implementation of the interface `IPersonDetailsCache` puts XML that is created in the response for Person details request to the cache. As a result method `RegisterPersonAndWaitForDetailsInCaseOfDuplicates` gets the XML from the cache as well.

Before starting listener implementation consider reading chapter 3.1.8 [Optional] Multi-server scenario as guidance in case when listener will be hosted as a separate web job. In that scenario own implementation of `IPersonDetailsCache` must be done.

When `BackgroundListener` receives a message with a request for person's details it will call a method `GetPersonDetails` on `PersonDetailsProvider` passing FIFA ID of a person. Therefore you have to provide implementation of `IPersonDetailsProvider` that makes a lookup (e.g. in your database) and returns a valid `PersonLocal` XML from FIFA Data Standard (http://data.fifaconnect.org). If for any reason record for a requested person is not found or cannot be returned, `PersonDetailsProvider` should return `null` or empty string.

Code snippet below shows how to provide sample PersonDetailsProvider.

    var provider = new YourPersonDetailsProvider();
    var listener = facade.ConfigureListener(provider);

    // start listening for new messages
    await listener.RunWithTimeout(TimeSpan.FromMinutes(10)).ConfigureAwait(false);

XML below is an example of data that should be returned by `PersonDetailsProvider`

    <?xml version="1.0" encoding="UTF-8"?>
    <PersonLocal xmlns="http://fifa.com/fc" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xmime="http://www.w3.org/2005/05/xmlmime" PersonFIFAId="105C3Z1" LocalFirstName="ΑΓΓΕΛΗΣ" LocalLastName="ΧΑΡΑΛΑΜΠΟΥΣ" LocalLanguage="gre" LocalCountry="CY" LocalSystemMAId="1234567" InternationalFirstName="ANGELIS" InternationalLastName="CHARALAMBOUS" Gender="male" DateOfBirth="1989-05-31" PlaceOfBirth="Larnaca" RegionOfBirth="Larnaca" CountryOfBirth="CY" Nationality="CY">
        <NationalIdentifier Identifier="GHKJKLD123132132" NationalIdentifierNature="PassportNumber" Country="CY" DateFrom="2010-08-13" DateTo="2020-08-13"/>
        <PlayerRegistration PersonFIFAId="105C3Z1" Status="active" OrganisationFIFAId="105C40I " RegistrationValidFrom="2003-04-11" RegistrationValidTo="2009-06-15" Discipline="Football" Level="amateur" RegistrationNature="Registration"/>
        <PlayerRegistration PersonFIFAId="105C3Z1" Status="active" OrganisationFIFAId="105C40I " RegistrationValidFrom="2009-06-16" Discipline="Football" Level="pro" RegistrationNature="Registration"/>
        <TeamOfficialRegistration PersonFIFAId="105C3Z1" Status="active" OrganisationFIFAId="105C40I" RegistrationValidFrom="2012-08-13" RegistrationValidTo="2014-08-13" Discipline="Futsal" TeamOfficialRole="Coach"/>
    </PersonLocal>

#### 3.1.3.1 Prepare data for XML serialization

SDK doesn't restrict any method of generating string with XML content. Recommended and by far the easiest method, however, is using `PersonLocalXmlSerializer` class, that we provided in SDK.

> Important note: The SDK does XML validation using an XSD schema. To learn more about correct setup, please refer to part "2.4 XSD schema for validation"

    var xsdFilesResolver = new XsdSchemasDirectoryResolver(@"C:\custom\directory\where\scenarios.xsd\is\located");
    var serializer = new PersonLocalXmlSerializer(xsdFilesResolver);

All that is required is to run the method `Serialize()` which takes `PersonLocal` object as an input. All required fields (in accordance with FIFA Data Standard) must be provided, otherwise any deficiencies will be detected during validation. This rule applies for all model classes used in XML serialization process. Check below example to see how to create `PersonLocal` object with required and optional fields.

    // creating an instance of the object
    // required fields
    var personLocal = new PersonLocal("ΧΑΡΑΛΑΜΠΟΥΣ", Gender.Male, ISO3166CountryCode.CY,
        new DateTime(1990, 11, 11), ISO316613CountryCode.CY, "Larnaca", ISO6392LanguageCode.Gre,
        ISO3166CountryCode.CY, "105C3Z1");

    // optional fields
    personLocal.LocalFirstName = "ΑΓΓΕΛΗΣ";
    personLocal.LocalSystemMAId = "1234567";
    personLocal.InternationalFirstName = "ANGELIS";
    personLocal.InternationalLastName = "CHARALAMBOUS";
    personLocal.RegionOfBirth = "Larnaca";
    personLocal.SecondNationality = ISO3166CountryCode.GR;
    personLocal.PopularName = "Angelis Angeli";

`PersonLocal` created this way contains general information of the person whose details will be sent to other MA. Another business context are registrations. Each registration type can be included in XML file by adding new elements to lists by following methods: `AddPlayerRegistration()`, `AddTeamOfficialRegistration()`, `AddMatchOfficialRegistration()` and `AddOrganisationOfficialRegistration()`. As all types are very similar to each other (as all extend `Registration` class), let's focus on how to set up `PlayerRegistration` and link it with `PersonLocal` object:

    // PersonDetailsRequest is available in GetPersonDetails() method of IPersonDetailsProvider interface
    var request = new PersonDetailsRequest("replyTo", "fifaId", "correlationId", null);
    var personFIFAId = request.UniqueFifaId;
    var clubOrMemberAssociationId = "105C40I";

    // creating an instance of the object
    var personLocal = new PersonLocal("ΧΑΡΑΛΑΜΠΟΥΣ", Gender.Male, ISO3166CountryCode.CY,
        new DateTime(1990, 11, 11), ISO316613CountryCode.CY, "Larnaca", ISO6392LanguageCode.Gre,
        ISO3166CountryCode.CY, personFIFAId);

    // create an instance of player registration
    var playerRegistration = new PlayerRegistration(personFIFAId, Status.Active, clubOrMemberAssociationId, new DateTime(2003, 4, 11),
        RegistrationLevel.Amateur, Discipline.Football, PlayerRegistrationNature.Registration);

    // optional fields
    playerRegistration.RegistrationValidTo = new DateTime(2006, 6, 15);
    playerRegistration.ClubTrainingCategory = ClubTrainingCategory.Category3;

    // include player registration in PersonLocal
    personLocal.AddPlayerRegistration(playerRegistration);

Another important field, which can be set in `PersonLocal` in similar way as registrations, is `Photo`. This property itself is not required, but when using it, a mandatory instance of `PictureEmbedded` class needs to be passed as a constructor argument. SDK gives two possibilities when preparing `PictureEmbedded` object: using byte[] array (`new PictureEmbedded(byte[] image)`) or using path to local file (`new PictureEmbedded(string localPath)`). Below example shows what's the approach here:

    // creating an instance of the object
    var personLocal = new PersonLocal("ΧΑΡΑΛΑΜΠΟΥΣ", Gender.Male, ISO3166CountryCode.CY,
        new DateTime(1990, 11, 11), ISO316613CountryCode.CY, "Larnaca", ISO6392LanguageCode.Gre,
        ISO3166CountryCode.CY, "105C3Z1");

    // add all mandatory fields
    var absolutePathToPhoto = "C:\\image.png";
    var picture = new PictureEmbedded(absolutePathToPhoto);

    // include photo in PersonLocal
    personLocal.Photo = new Photo(picture);

SDK supports following image formats: jpg, png, gif, tif, bmp. Please mind that the maximum size of a person details message sent through Service Bus is approximately 10MB. You might want to ensure that the size of the photo does not make the entire PersonLocal object exceed that limit. A reasonable boundary for a PNG file is 8MB.

`NationalIdentifier` and `LocalPersonName` are both optional in `PersonLocal` scope and there is no difference in rules with setting their properties comparing to other fields. See example of `NationalIdentifier` below:

    // creating an instance of the object
    var personLocal = new PersonLocal("ΧΑΡΑΛΑΜΠΟΥΣ", Gender.Male, ISO3166CountryCode.CY,
            new DateTime(1990, 11, 11), ISO316613CountryCode.CY, "Larnaca", ISO6392LanguageCode.Gre,
            ISO3166CountryCode.CY, "105C3Z1");

    // create an instance of player registration
    var nationalIdentifier = new NationalIdentifier("9876543210", NationalIdentifierNature.PassportNumber, ISO3166CountryCode.CY);

    // optional fields
    nationalIdentifier.Description = "NationalIdentifier test description";
    nationalIdentifier.DateFrom = new DateTime(2003, 4, 11);
    nationalIdentifier.DateTo = new DateTime(2004, 6, 1);

    // include national identifier in PersonLocal
    personLocal.AddNationalIdentified(nationalIdentifier);

#### 3.1.3.2 Serialize XML document

After `PersonLocal` object is created, you need to pass it to `Serialize()` method of `PersonLocalXmlSerializer` service. Under the hood, this method creates XML string and executes validation against FIFA Data Standard. In case validation fails, `XmlSerializationException` will be thrown giving a message with all possible issues that were found during validation. As all of this happens in background listener, you should implement a proper error handling when catching the exception, so to get notified in case when XML response was not generated. Note that in case of exception thrown, MA that was asking for person details, won't receive a correct answer, so it's important to keep data structure valid and try to limit number of exceptions.

    // creating an instance of the object
    var personLocal = new PersonLocal("ΧΑΡΑΛΑΜΠΟΥΣ", Gender.Male, ISO3166CountryCode.CY,
        new DateTime(1990, 11, 11), ISO316613CountryCode.CY, "Larnaca", ISO6392LanguageCode.Gre,
        ISO3166CountryCode.CY, "105C3Z1");

    var xmlSerializer = new PersonLocalXmlSerializer();

    String xmlString = null;
    try {
        xmlString = xmlSerializer.Serialize(personLocal);
    }
    catch (XmlSerializationException e) {
        var validationErrors = e.XmlValidationErrors;
        // handle serialization exception
    }

#### 3.1.3.3 (Optional) XML validation

As `PersonLocalXmlSerializer` includes XML validation, there is no need of running additional validation over it. But, in case of internal unit tests or when instead of our helper tool, custom solution produces XML content, it is possible to check whether output is compliant with FIFA Data Standard. To achieve that, use `XsdSchemaValidator` as on following example:

    //Invalid xml string
    var xmlString = "xmlString";
    var xsdSchemaValidator = new XsdSchemaValidator();
    var validationResult = xsdSchemaValidator.Validate(xmlString);

    if (!validationResult.IsValid) {
        // handle validation errors
        var validationErrors = validationResult.ValidationFailures;
    }

> Important note: Alternatively you can use a custom `IDirectoryResolver` for providing custom path to `\Resources\Xsd\scenarios.xsd` file location. To achieve that you need to create a class implementing `IDirectoryResolver` and use overloaded constructor `XsdSchemaValidator(IDirectoryResolver xsdDirectoryResolver)`.

#### 3.1.3.4 (Optional) Clean-up of old messages

When configuring the listener, an implementation of `ICacheCleanJob` can be provided, that will run alongside the listener and take care of the removal of old messages. You can use the default implementation provided by the SDK (`PersonDetailsCacheCleanJob`) or create your own.

    var provider = new YourPersonDetailsProvider();
    var cleanJobSettings = new PersonDetailsCacheCleanJobSettings(facadeSettings.PersonDetailsCache);
    var cleanJob = new PersonDetailsCacheCleanJob(cleanJobSettings); /* or YourOwnCleanJob */

    /* Please see section 6.1.1 for reference. If TMS integration is not within the scope of your integration, please provide a null value instead */
    var tmsHandlers = TmsFacadeHandlersFactory.CreateMessageHandlers(responsesCache);
    var listener = facade.ConfigureListener(provider, tmsHandlers, cleanJob);

### 3.1.4 (Step 4) [Optional] Subscribe to other events from Connect Service Bus

Additionally an instance of the `BackgroundListener` class exposes the following events:

- `PersonDetailsRequestReceived`
- `PersonDetailsReceived`
- `GenericMessageReceived`
- `ServiceBusExceptionEvent`

These events are automatically raised by the listener. You can use them to register your own event handlers and provide additional logic for handling received messages.

    listener.PersonDetailsReceived += details =>
    {
        // do something with those details
    };

    listener.GenericMessageReceived += message =>
    {
        var bytes = message.Content;
        var actionName = message.Action;
    };

If a message received from Connect Service Bus is processed properly by all registered handlers (no exceptions are thrown), then the message is marked as processed and deleted from the Connect Service Bus queue. In case any handler throws an exception, a message will not be deleted from the Connect Service Bus but will be scheduled for later processing. `BackgroundListener` will try to process this message, but after a series of unsuccessful handles, a message will be moved to a dead messages queue, which will be monitored by FIFA Connect ID Helpdesk.

### 3.1.5 (Step 5) Register a new person

First create a person you want to register:

    var organisationId = "id";

    // setup player name(s)
    var personNames = new List<PersonName>
    {
        new PersonName("John", "Doe")
    };

    // setup birthdate
    var dateOfBirth = new DateTime(1990, 10, 12);
    var person = new PersonType
    {
        DateOfBirth = dateOfBirth
    };

    // setup registrations
    var registration = new PlayerRegistrationType
    {
        OrganisationFIFAId = organisationId,
        Status = "active",
        Level = "Pro",
        Discipline = "Football",
        RegistrationNature = "Registration"
    };

    person.PlayerRegistrations = new List<PlayerRegistrationType>
    {
        registration
    };

    // finally create PersonData
    var personData = new PersonData(personNames, person);

Then try to register a person using Registration Facade. The code snippet below shows an example handling (writing to console) of both scenarios, i.e. successful registration and potential duplicates found.

    /* A record identifier in your database or any other key that is unique for a person.
    This data will be stored hashed and cannot be decrypted.
    For further information please consult section 3.1.5.2 Idempotency */
    string personLocalId = "";
    TimeSpan timeout = TimeSpan.FromSeconds(10);

    var result = await facade.RegisterPersonAndWaitForDetailsInCaseOfDuplicates(
        personData, timeout, personLocalId).ConfigureAwait(false);

    if (result.IsSuccessful)
    {
        Console.WriteLine($"Person successfully registered with unique FIFA ID: {result.UniqueFifaId}.");
    }
    else {
        Console.WriteLine("Duplicates found.");

        foreach (var duplicateWithDetails in result.PersonDuplicateWithDetails)
        {
            var idOfDuplicatedPerson = duplicateWithDetails.Duplicate.PersonFifaId;
            var proximityScore = duplicateWithDetails.Duplicate.ProximityScore;
            var duplicatedPersonRegistrationDate = duplicateWithDetails.Duplicate.PersonRegistrationContext.RegistrationDate;

            // In order to determine which record is primary, it is recommended to consider the original registration date.
            // The following article provides more information: https://support.id.ma.services/support/solutions/articles/7000080785-merging-how-to-decide-which-record-is-primary

            var dataReceived = duplicateWithDetails.PersonDetails == null
                ? "<detailed person data not received from other MA - timeout>"
                : duplicateWithDetails.PersonDetails.XmlData;

            Console.WriteLine($"FIFA ID: {idOfDuplicatedPerson}, score: {proximityScore}, registration date: {duplicatedPersonRegistrationDate:d}, FIFA Data XML: {dataReceived}");
        }
    }

Service Bus listener must be up and running to receive person details. There may be cases where a person has no registrations, but still appears on the list of duplicates as FIFA Data Standard does not require any registrations to construct a valid object. Connect Id stores computed hashes, but has no way of knowing which MA to ask for the details, so as a result null XML will be returned. In addition to that, for every potential duplicate there will be a hash score computed, ranging from 0 (no resemblance) to 1 - exact match. Your system should be prepared to handle duplicates, considering both the possibility of receiving incomplete data and the value of the hash score.

##### Troubleshooting

Please keep in mind that, especially in the Beta environment, some of the listeners of other Member Associations might not be working. The method waits a specified period of time for the details to arrive and returns without them afterwards.

If you are certain that both your and the other MA's listener are up and running and you still do not receive person details, make sure that a valid implementation of `IPersonDetailsCache` is used. More on the subject can be found in the chapter 3.1.8.

Detailed explanation of handling forementioned issues can be found under this FAQ article.

#### 3.1.5.1 Handling multiple names (local, international and maiden/birth names)

SDK provides support for registering a person with multiple names. Two scenarios will usually require such a feature:

- registering a person for which local spelling differs from international spelling (e.g. from a non-Latin alphabet country)
- registering a person with both last name and maiden name

Before registering a person, you need to create a list of pairs of names (`List<PersonName>`) . The following example shows the most sophisticated scenario when a single person has both: local name, international name and maiden name provided. Although two pairs of names will be used in minority of cases and three pairs hardly ever, the example is instructive.

    var internationalFirstName = "Olga";
    var internationalLastName = " Terekhova";
    var localFirstName = "Ольга";
    var localLastName = "Терехова";
    var localMaidenName = "Бори́совна";

    var personInternationalName = new PersonName(internationalFirstName, internationalLastName);
    var personLocalName = new PersonName(localFirstName, localLastName);
    var personMaidenName = new PersonName(localFirstName, localMaidenName);

    // setup player name(s)
    var personNames = new List<PersonName>();

    personNames.Add(personInternationalName);
    personNames.Add(personLocalName);
    personNames.Add(personMaidenName);

These names must then be used to populate object of type `Fifa.ConnectId.Sdk.Core.XmlParser.Models.PersonData`.

#### 3.1.5.2 Idempotency (recommended)

Idempotency ensures that the same record is saved only once even when multiple registration requests are sent. To ensure that the same record is not registered in the system twice we recommend to pass person local identifier when registering person (Person local id can be a record identifier in your database or any other key that is unique for a person). Local identifier will be useful in case of retries on the client side (e.g. due to network issues or occasional client time-outs). It is sent and stored on the server in a hashed form (SHA-512 is used by default by SDK) and cannot be decrypted.

If you choose not to take advantage of the idempotency mechanism, you should expect that in rare situations FIFA_ID will be created on/by the server but you will not receive it on the client. Should this happen, the next time you try to register the same person, you will receive a duplicate pointing to your Member Association, but without any details (as your listener will not be able to provide details for the person which FIFA_ID you have not received).

##### Using person local identifier

The only thing that you need to do to start using idempotency mechanism is to pass additional parameter (local person identifier) to `ForceRegisterPerson` or `RegisterPersonAndWaitForDetailsInCaseOfDuplicates` methods on `RegistrationFacade`. Based on the method that is used the system behaves as follows:

- when using `RegisterPersonAndWaitForDetailsInCaseOfDuplicates`
  Take a look at the following example:

    var personLocalIdentifier = "Person Local Id";
    var result = await facade.RegisterPersonAndWaitForDetailsInCaseOfDuplicates(personData, TimeSpan.FromSeconds(10), personLocalIdentifier).ConfigureAwait(false);

In the example above, the `RegisterPersonAndWaitForDetailsInCaseOfDuplicates` will check it there is no other registration with the same person local identifier. If the registration with the same person local identifier exists, it will be returned as a result. There will be no second registration nor the update of an existing one. If there is no registration with the same person local identifier, the method will run the default logic of searching for duplicates and registering a new person. Person local identifier will be stored on the server in the hashed form for the newly created record.

Please note, that the use of the `ForceRegisterPerson` does not change the behaviour, i.e. a new person will not be created if the same person local identifier is used.

##### Custom hashing method for encrypting local identifier

Optionally, you are allowed to change a default mechanism (SHA-512 hashing) of encrypting local identifier. Code snippet below presents how to do that by implementing `IHashedPersonProcessor` interface. Provided implementation needs to be passed to `RegistrationFacadeSettings` class when creating registration facade. Please take a look at the following example:

    public class CustomHashedPersonHashingMechanismProcessor : IHashedPersonProcessor
    {
        public HashedPersonType Process(HashedPersonType hashedPersonType)
        {
            var localPersonIdHash = "Make hashing here";
            return new HashedPersonType(hashedPersonType.NameHashes, hashedPersonType.Person, localPersonIdHash);
        }
    }

    var settings = new RegistrationFacadeSettings()
    {
        HashedPersonProcessor = new CustomHashedPersonHashingMechanismProcessor()
    };

    var facade = new RegistrationFacade(connectIdEnvironment, clientCredentials, privateKeyStorage, logger, settings);

### 3.1.6 Update person

First create two persons and register them:

    // setup player name(s)
    var person1Names = new List<PersonName>
    {
        new PersonName("John", "Doe")
    };
    var person2Names = new List<PersonName>
    {
        new PersonName("John", "Kowalsky")
    };

    // setup birthdate
    var dateOfBirth = new DateTime(1990, 10, 12);
    var person = new PersonType
    {
        DateOfBirth = dateOfBirth,
        Gender = "male"
    };

    // setup registrations
    var registration = new PlayerRegistrationType
    {
        OrganisationFIFAId = organisationId,
        Status = "active",
        Level = "Pro",
        Discipline = "Football",
        RegistrationNature = "Registration"
    };

    person.PlayerRegistrations = new List<PlayerRegistrationType>
    {
        registration
    };

    // finally create PersonData
    var person1Data = new PersonData(person1Names, person);
    var person2Data = new PersonData(person2Names, person);

    //register two different players
    facade.ForceRegisterPerson(person1Data);
    facade.ForceRegisterPerson(person2Data);

Then try to update second person using Registration Facade with names of first person. The code snippet below shows an example handling (writing to console) of both scenarios, i.e. successful update and potential duplicates found. Please note that this operation will throw an `InvalidClientDataException` if you lack the permissions to perform it (the player has active registrations, none of which belongs to your MA).

    var result = await facade.UpdatePersonAndWaitForDetailsInCaseOfDuplicates(personId, TimeSpan.FromSeconds(10), names, dateOfBirth, gender).ConfigureAwait(false);

    if (result.IsSuccessful)
    {
        Console.WriteLine($"Person updated successfully.");
    }
    else
    {
        Console.WriteLine("Duplicates found.");

        foreach (var duplicateWithDetails in result.PersonDuplicateWithDetails)
        {
            var idOfDuplicatedPerson = duplicateWithDetails.Duplicate.PersonFifaId;
            var proximityScore = duplicateWithDetails.Duplicate.ProximityScore;
            var duplicatedPersonRegistrationDate = duplicateWithDetails.Duplicate.PersonRegistrationContext.RegistrationDate;

            // In order to determine which record is primary, it is recommended to consider the original registration date.
            // The following article provides more information: https://support.id.ma.services/support/solutions/articles/7000080785-merging-how-to-decide-which-record-is-primary

            var dataReceived = duplicateWithDetails.PersonDetails == null
                ? "<detailed person data not received from other MA - timeout>"
                : duplicateWithDetails.PersonDetails.XmlData;

            Console.WriteLine($"FIFA ID: {idOfDuplicatedPerson}, score: {proximityScore}, registration date: {duplicatedPersonRegistrationDate:d}, FIFA Data XML: {dataReceived}");
        }
    }

### 3.1.7 [Optional] Get person duplicates (without registering)

If you need to get list of duplicates for a person, method `GetDuplicates` can be used. This methods looks for duplicates in Connect ID service. If any duplicate is found requests for person details are sent to relevant MAs. It is possible to look for duplicates only within specific organisations by providing `organisationsIds` argument.

    var foundDuplicates = await facade.GetDuplicates(personData, TimeSpan.FromSeconds(10)).ConfigureAwait(false);

    if (foundDuplicates.Count > 0)
    {
        Console.WriteLine("Duplicates found.");

        foreach (var duplicateWithDetails in foundDuplicates)
        {
            var idOfDuplicatedPerson = duplicateWithDetails.Duplicate.PersonFifaId;
            var proximityScore = duplicateWithDetails.Duplicate.ProximityScore;
            var duplicatedPersonRegistrationDate = duplicateWithDetails.Duplicate.PersonRegistrationContext.RegistrationDate;

            // In order to determine which record is primary, it is recommended to consider the original registration date.
            // The following article provides more information: https://support.id.ma.services/support/solutions/articles/7000080785-merging-how-to-decide-which-record-is-primary

            var dataReceived = duplicateWithDetails.PersonDetails == null
                ? "<detailed person data not received from other MA - timeout>"
                : duplicateWithDetails.PersonDetails.XmlData;

            Console.WriteLine($"FIFA ID: {idOfDuplicatedPerson}, score: {proximityScore}, registration date: {duplicatedPersonRegistrationDate:d}, FIFA Data XML: {dataReceived}");
        }
    }

#### 3.1.7.1 [Optional] Get person duplicates by FIFA identifier

To get the list of duplicates for a registered person, use method `GetDuplicatesExceptTrustedKnownDuplicates`. To ignore duplicates marked as known duplicate by trusted organisations, please provide optional `trustedOrganisationsIds` argument.

    const string personFifaId = "105C40T";
    var result = await facade.GetDuplicatesExceptTrustedKnownDuplicates(personFifaId, TimeSpan.FromSeconds(10)).ConfigureAwait(false);
    var foundDuplicates = result.Duplicates;
    var personRegistrationContext = result.RequestedPersonRegistrationContext;
    var registrationDate = personRegistrationContext.RegistrationDate; // can be used to compare with a duplicate's registration date

    foreach (var duplicateWithDetails in foundDuplicates)
    {
        var idOfDuplicatedPerson = duplicateWithDetails.Duplicate.PersonFifaId;
        var proximityScore = duplicateWithDetails.Duplicate.ProximityScore;
        var duplicatedPersonRegistrationDate = duplicateWithDetails.Duplicate.PersonRegistrationContext.RegistrationDate;

        // In order to determine which record is primary, it is recommended to consider the original registration date.
        // The following article provides more information: https://support.id.ma.services/support/solutions/articles/7000080785-merging-how-to-decide-which-record-is-primary

        var dataReceived = duplicateWithDetails.PersonDetails == null
            ? "<detailed person data not received from other MA - timeout>"
            : duplicateWithDetails.PersonDetails.XmlData;

        Console.WriteLine($"FIFA ID: {idOfDuplicatedPerson}, score: {proximityScore}, registration date: {duplicatedPersonRegistrationDate:d}, FIFA Data XML: {dataReceived}");
    }

### 3.1.8 Advanced listener configuration

If your infrastructure for the application using SDK consists of multiple servers or your listener and registration facade are running in separate processes, then additional configuration is required.

One of the most important things to consider when choosing the way you want to host your listener is that it requires a shared storage between all instances of the SDK. The request has to be matched with response at some point. In order for this correlation to work, an ID of the request message (so called Correlation Id) needs to be stored and later retrieved by our code. For example, when sending the requests like: `RegisterPersonAndWaitForDetailsInCaseOfDuplicates` or `GetDuplicates` the Correlation Id is created for them. Once the information is back from another NRS or ConnectID it also contains the same Correlation Id - this way the listener knows which response should be matched with the request.

By default, this matching is done in the memory and you don't need to code anything. However, it may not always be true, especially when hosting the listener in the cloud (e.g. as Azure WebJob) or when having multiple instances of NRS system (and in effect: multiple instances of the SDK). In such case, some additional configuration is required. SDK defines the `IPersonDetailsCache` interface, which must be implemented by the client of the SDK and passed into `RegistrationFacadeSettings`.

Examples of implementation of `IPersonDetailsCache` are:

- SQL database - shared state is stored in SQL table (MySQL, SQL Server, Oracle)
- cache server - shared state is stored in cache server (e.g. Redis)
- shared disk - shared state is stored as a set of files which are stored on a shared drive (e.g. using Samba protocol)

Code snippet below presents how to register `YourSharedStorage` in `RegistrationFacade`:

    var settings = new RegistrationFacadeSettings
    {
        PersonDetailsCache = new YourSharedStorage()
    };

    var facade = new RegistrationFacade(environment, clientCredentials, logger, settings);

In the above example `YourSharedStorage` implements mentioned `IPersonDetailsCache` interface by providing three methods:

- `void Put(PersonDetails personDetails)` - inserts records in shared storage
- `PersonDetails GetByCorrelationId(String correlationId)` - gets record from shared storage by id. If there is no entry associated with the given id, this method should return a `null` value
- `void DeleteOlderThan(Duration duration)` - for cleanup purposes it deletes old records

    public interface IPersonDetailsCache
    {
        /// <summary>
        /// Puts person details into storage mechanism.
        /// </summary>
        void Put(PersonDetails personDetails);

        /// <summary>
        /// Get person details with given correlation id from storage mechanism.
        /// </summary>
        PersonDetails GetByCorrelationId(string correlationId);

        /// <summary>
        /// Deletes the entries from storage mechanism that are older than given date.
        /// </summary>
        void DeleteOlderThan(TimeSpan duration);
    }

### 3.1.8.1 [Optional] Best practices for hosting Listener as Azure WebJob

- How to use an SSL certificate in your application code in Azure App Service
- Use settings.job file with { "is_in_place": true} setting
- In Application Settings set `Always On` setting to `On`
- If you use Entity Framework remember to Initialize EF Context after Listener restart
- Remember about `IPersonDetailsCache` from `3.1.8` point in documentation

### 3.1.9 Deserialize XML with person details

When running operations that could possibly return person’s duplicates (such us registering persons, updating persons, etc.), methods will return responses with list of `PersonDuplicateWithDetails`. `PersonDetails` that have been received here contains an XML content, which is available in `XmlData` property. At this point application can store all details in local database (or handle them in a different way - depending on a need), so that it is possible to compare person being processed with their potential duplicates.

Optionally, after receiving XML string from `XmlData`, you may parse it into object. This can be done with a custom implementation, however the suggested solution here is to use `PersonLocalXmlSerializer` class (provided by our SDK) and its `Deserialize()` method returning `PersonLocal` object. Take a look at the following example:

    var xmlSerializer = new PersonLocalXmlSerializer();

    try
    {
        var personLocal = xmlSerializer.Deserialize(personDuplicateWithDetails.PersonDetails.XmlData);
    }
    catch (XmlDeserializationException ex)
    {
        var xmlContent = ex.Xml;
        var innerException = ex.InnerException;
    }

### 3.1.10 Known limitations of Registration Facade

#### Available operations

Registration Facade covers scenario of person registration/update/search, but for other functionalities FIFA ID Client described in the next chapter must be used.

In particular FIFA Connect ID Client must be used for:

- force registration of a person
- getting person data from FIFA Connect ID Directory
- all operations on organisation and facility

#### Concurrent requests

Currently there is no request throttling in API, but it's recommended not to exceed 10 concurrent connections. Too many requests to API may result in requests time outs. In case you plan to do a batch import of person records, please contact support team so that the infrastructure can be scaled up accordingly.

## 3.2 Using FIFA Connect ID Client

This chapter discusses all operations on a Person entity, e.g. Registration, Update, Merge, etc. It is different from chapter 3.1 Using Registration Facade in that operations described here do not involve a duplicate check. A developer who wants to perform a duplicate check via Service Bus should either refer to chapter 3.1 or implement communication via Service Bus by themselves.

### 3.2.1 Creating a client

The entry point of the SDK is `FifaConnectIdClient`. With a single instance of this class all the requests can be made. In order to authenticate to the service you have to provide a set of client credentials.

Note that in most cases you don't need to create `FifaConnectIdClient` instance. Having `RegistrationFacade` object, you can get the client as shown in below example:

    var client = facade.ConnectIdClient;

#### 3.2.1.1 Basic instance

    var environment = ConnectIdEnvironment.Beta;
    var credentials = new ClientCredentials("clientId", "secretKey");
    var logger = new YourOwnLogger();

    var client = new FifaConnectIdClient(environment, credentials, logger);

where environment is an instance of type `ConnectIdEnvironment`. It provides information about the service to make request to.

#### 3.2.1.2 Actor

In addition you can provide information about the current user interacting with the Registration System. This can be accomplished by providing implementation of `IActorResolver` interface. Such actor resolver could be much more advanced than `SimpleActorResolver` provided as a default implementation. In case of web application, actor could be fetched from current web request context.

    IActorResolver actorResolver = new SimpleActorResolver("John Doe");
    var client = new FifaConnectIdClient(environment, clientCredentials, logger, actorResolver);

#### 3.2.1.3 Creating custom environment instance

As there are some pre-defined environments defined in the `ConnectIdEnvironment` class, it's also possible to create a custom instance using environment code. In order to achieve that, environment code needs to be provided to the static factory method.

    var environmentCode = "envcode";
    var environment = ConnectIdEnvironment.Create(environmentCode);

Use one of the existing environments:

Environment | Environment code
--- | ---
Integration | int
Hotfix | hfix
Beta | beta
Preproduction | prep
Production | prod

### 3.2.2 Registering a person

In order to register a person in FIFA Connect ID service, provide a `PersonData` object. Here is an example, that registers a person:

    var names = new[]
    {
       new PersonName("ΑΓΓΕΛΗΣ", "ΧΑΡΑΛΑΜΠΟΥΣ"), // local name
       new PersonName("ANGELIS", "CHARALAMBOUS") // international name
    };

    var person = new PersonType
    {
       DateOfBirth = new DateTime(1980, 10, 10),
       // fill up registrations
    };

    var personData = new PersonData(names, person);

    /* A record identifier in your database or any other key that is unique for a person.
    This data will be stored hashed and cannot be decrypted.
    For further information please consult section 3.1.5.2 Idempotency */
    string personLocalId = "";

    try
    {
       var uniqueFifaId = await client.RegisterPersonAsync(personData, personLocalId);
    }
    catch (ValidationException)
    {
        // provided data did not pass validation
    }
    catch(AuthenticationException ex)
    {
        // invalid client credentials
    }
    catch(UnauthorizedException ex)
    {
        // unauthorized
    }
    catch (InvalidClientDataException ex)
    {
       // data sent to the service was invalid
       var details = ex.BadRequestResponse;
    }
    catch (FifaDuplicatedPersonFoundException ex)
    {
       // possible duplicates were found
       var duplicates = ex.GetDuplicatesResponseType.Duplicates;
    }
    catch (TooManyRequestsException ex)
    {
        // call rate limit was exceeded
        var retryAfterInSeconds = ex.RetryAfter;
    }
    catch (FifaConnectIdException ex)
    {
       // some other error occurred, see the details
       var operationResponse = ex.HttpOperationResponse;
    }

#### 3.2.2.1 Person bulk registration

In order to register persons in parallel you can use Task Parallel Library. Please note that in order to optimize costs of test environment we keep it small-scale. Let us know upfront if you plan to test bulk registration, so we can scale up the environment. Additionally we recommend not exceeding 20 concurrent registrations to avoid performance degradation of the service. Take a look at the following example:

    var database = new LocalDatabase();
    var players = database.Players.Where(x => x.FifaId == null);

    players
        .AsParallel()
        .WithDegreeOfParallelism(10)
        .ForAll(player =>
        {
            PersonData personData = CreatePerson(player);
            string fifaId = client.RegisterPersonAsync(personData).Result;

            database.UpdateFifaId(player.Id, fifaId);
        });

### 3.2.3 Force registration

To force the registration process (proceed even if potential duplicates are found):

    /* A record identifier in your database or any other key that is unique for a person.
    This data will be stored hashed and cannot be decrypted.
    For further information please consult section 3.1.5.2 Idempotency */
    string personLocalId = "";

    try
    {
        var uniqueFifaId = await client.ForceRegisterPersonAsync(personData, personLocalId);
    }
    catch (ValidationException)
    {
        // provided data did not pass validation
    }
    catch(AuthenticationException ex)
    {
        // invalid client credentials
    }
    catch(UnauthorizedException ex)
    {
        // unauthorized
    }
    catch (InvalidClientDataException ex)
    {
        // data sent to the service was invalid
        var details = ex.BadRequestResponse;
    }
    catch (TooManyRequestsException ex)
    {
        // call rate limit was exceeded
        var retryAfterInSeconds = ex.RetryAfter;
    }
    catch (FifaConnectIdException ex)
    {
        // some other error occurred, see the details
        var operationResponse = ex.HttpOperationResponse;
    }

### 3.2.4 Getting person data

This method will throw `FifaPersonMergedException` when you try to get data for a person that has been previously merged (refer to section 3.2.5 Merging/unmerging persons). The exception will contain data about requested person together with primary person id. To get the information associated with the specified FIFA ID such as a date of birth or list of person's registrations:

    try
    {
        var uniqueFifaId = "BVGE8T6";
        var person = await client.GetPersonAsync(uniqueFifaId);
    }
    catch (ValidationException)
    {
        // provided data did not pass validation
    }
    catch(AuthenticationException ex)
    {
        // invalid client credentials
    }
    catch(UnauthorizedException ex)
    {
        // unauthorized
    }
    catch (InvalidClientDataException ex)
    {
        // data sent to the service was invalid
        var details = ex.BadRequestResponse;
    }
    catch (FifaEntityNotFoundException ex)
    {
        // could not find the person
        var operationResponse = ex.HttpOperationResponse;
    }
     catch (FifaEntityDeletedException ex)
    {
        // person has been deleted
        var operationResponse = ex.HttpOperationResponse;
    }
    catch (FifaPersonMergedException ex)
    {
        // requested person has been merged
        var person = ex.RequestedEntity;
        var primaryPersonId = ex.PrimaryEntityId;
    }
    catch (TooManyRequestsException ex)
    {
        // call rate limit was exceeded
        var retryAfterInSeconds = ex.RetryAfter;
    }
    catch (FifaConnectIdException ex)
    {
        // some error occurred, see the details
        var operationResponse = ex.HttpOperationResponse;
    }

### 3.2.5 Merging/unmerging persons

To merge two persons into a single one use `MergePersonsAsync` method available on `FifaConnectIdClient`. As a result, the primary person data will be kept. No more operations should be executed on the secondary person. Attempt to get secondary person's data will result in 301 error code. Please refer to section 3.2.4 Getting person data. This operation can end with conflict error under specific conditions. It can happen when previous merge/unmerge operation is not yet completed on the same persons. As a result `FifaConflictException` will be thrown and client should retry operation later.

You can find more information on the subject in our portal.

Here is an example how to merge persons:

    try
    {
        var person = await client.MergePersonsAsync(primaryPersonId, secondaryPersonId).ConfigureAwait(false);
    }
    catch (ValidationException)
    {
        // provided data did not pass validation
    }
    catch (AuthenticationException ex)
    {
        // invalid client credentials
        var details = ex.HttpOperationResponse;
    }
    catch (UnauthorizedException ex)
    {
        // unauthorized
        var details = ex.HttpOperationResponse;
    }
    catch (InvalidClientDataException ex)
    {
        // data sent to the service was invalid
        var details = ex.BadRequestResponse;
    }
    catch (FifaConflictException ex)
    {
        // a conflicting operation is currently in progress
        var details = ex.Response;
    }
    catch (FifaEntityNotFoundException ex)
    {
        // could not find one of specified persons
        var operationResponse = ex.HttpOperationResponse;
    }
    catch (TooManyRequestsException ex)
    {
        // call rate limit was exceeded
        var retryAfterInSeconds = ex.RetryAfter;
    }
    catch (FifaConnectIdException ex)
    {
        // some error occurred, see the details
        var operationResponse = ex.HttpOperationResponse;
    }

In order to revert merge operation call `UnmergePersonsAsync` method with the same arguments.

### 3.2.6 Getting duplicates

To get a list of people a person may be duplicated with:

    try
    {
        var potentialDuplicates = await client.GetDuplicatesAsync(personData);

        foreach (var duplicate in potentialDuplicates)
        {
            var idOfDuplicatedPerson = duplicate.PersonFifaId;
            var proximityScore = duplicate.ProximityScore;
            var duplicatedPersonRegistrationDate = duplicate.PersonRegistrationContext.RegistrationDate;

            // In order to determine which record is primary, it is recommended to consider the original registration date.
            // The following article provides more information: https://support.id.ma.services/support/solutions/articles/7000080785-merging-how-to-decide-which-record-is-primary
        }
    }
    catch (ValidationException)
    {
        // provided data did not pass validation
    }
    catch(AuthenticationException ex)
    {
        // invalid client credentials
    }
    catch(UnauthorizedException ex)
    {
        // unauthorized
    }
    catch (InvalidClientDataException ex)
    {
        // data sent to the service was invalid
        var details = ex.BadRequestResponse;
    }
    catch (TooManyRequestsException ex)
    {
        // call rate limit was exceeded
        var retryAfterInSeconds = ex.RetryAfter;
    }
    catch (FifaConnectIdException ex)
    {
        // some error occurred, see the details
        var operationResponse = ex.HttpOperationResponse;
    }

This method is expected to be used rarely, e.g. in cases when Registration System chooses to do a duplicate check without the registration. It is possible to look for duplicates only within specific organisations by providing `organisationsIds` argument.

#### 3.2.6.1 Getting duplicates by FIFA identifier

To get a list of people a registered person may be duplicated with:

    try
    {
        const string personFifaId = "105C408";
        var duplicates = await client.GetDuplicatesExceptTrustedKnownDuplicates(personFifaId).ConfigureAwait(false);

        var requestedPersonRegistrationContext = response.RequestedPersonRegistrationContext;
        var registrationDate = requestedPersonRegistrationContext.RegistrationDate; // can be used to compare with a duplicate's registration date

        foreach (var duplicate in response.Duplicates)
        {
            var idOfDuplicatedPerson = duplicate.PersonFifaId;
            var proximityScore = duplicate.ProximityScore;
            var duplicatedPersonRegistrationDate = duplicate.PersonRegistrationContext.RegistrationDate;

            // In order to determine which record is primary, it is recommended to consider the original registration date.
            // The following article provides more information: https://support.id.ma.services/support/solutions/articles/7000080785-merging-how-to-decide-which-record-is-primary
        }

    catch (ValidationException)
    {
        // provided data did not pass validation
    }
    catch (InvalidClientDataException ex)
    {
        // data sent to the service was invalid
        var details = ex.BadRequestResponse;

    {
        // some error occurred, see the details
        var operationResponse = ex.HttpOperationResponse;
    }

To ignore known duplicates registered by specific organisations, please provide optional `trustedOrganisationsIds` argument.

### 3.2.7 Add/Update registrations

It is possible to update an existing person record (provided that we know the person's FIFA ID) by adding or editing its registrations. In order to do that, use the class `AddRegistrationsRequestType` or `UpdateRegistrationsRequestType` (depending on the operation) and fill information about the registrations. Note, that each person always contains four collections of registrations:

- player registrations
- match official registrations
- team official registrations
- organisation official registrations

In the examples below, only player registrations are used - the other 3 collections remain empty (they are not set).

> Important note: Operation that results in Member Association (OrganisationFifaId) being changed for a given registration constitutes a transfer in ConnectId. Only one transfer at the same time is allowed. If you want to perform multiple transfers, please call `AddRegistrations` or `UpdateRegistrations` methods separately for each transfer.

#### 3.2.7.1 Add registrations

Note that in the example below a registration is added in a National Association and not in a Club. This is not a coincidence - FIFA Connect ID Service, although allowed to store Clubs in general, is not allowed to store persons' assignments to Clubs. Server will return an error should the Client try to register a person within a Club.

    const string personId = "105C408";
    const string organisationId = "105KYBB";

    var exampleRegistration = new PlayerRegistrationType();
    exampleRegistration.Level = "Pro";
    exampleRegistration.Discipline = "Football";
    exampleRegistration.RegistrationNature = "Registration";
    exampleRegistration.OrganisationFIFAId = organisationId;
    exampleRegistration.Status = "Active";

    var personRegistrations = new PersonRegistrationsType();
    personRegistrations.PlayerRegistrations = new List<PlayerRegistrationType>();
    personRegistrations.PlayerRegistrations.Add(exampleRegistration);

    var request = new AddRegistrationsRequestType(personId, personRegistrations);

    try
    {
        var personType = await client.AddRegistrations(request, false).ConfigureAwait(false);
    }
    catch (ValidationException)
    {
        // provided data did not pass validation
    }
    catch(AuthenticationException ex)
    {
        // invalid client credentials
    }
    catch(UnauthorizedException ex)
    {
        // unauthorized
    }
    catch (InvalidClientDataException ex)
    {
        // data sent to the service was invalid
        var details = ex.BadRequestResponse;
    }
    catch (FifaEntityNotFoundException ex)
    {
        // could not find the person
        var operationResponse = ex.HttpOperationResponse;
    }
    catch (TooManyRequestsException ex)
    {
        // call rate limit was exceeded
        var retryAfterInSeconds = ex.RetryAfter;
    }
    catch (FifaConnectIdException ex)
    {
        // some error occurred, see the details
        var operationResponse = ex.HttpOperationResponse;
    }

#### 3.2.7.2 Update registrations

In order to execute a request we need to know the registrations we want to update and their new values. Note that the order of registrations is important. Operation will try to change the first item in "old" list with the first item in the "new" list, etc.

"Old" list should contain only those registrations, which you want to update. For example, when person has four registrations and you want to update only two of them, you just need to provide these two.

    const string personId = "105C408";
    const string organisationId = "105KYBB";

    var person = await client.GetPersonAsync(personId).ConfigureAwait(false);

    var oldPersonRegistrations = new PersonRegistrationsType();
    oldPersonRegistrations.PlayerRegistrations = person.PlayerRegistrations;

    var newPlayerRegistration = new PlayerRegistrationType();
    newPlayerRegistration.Level = "Pro";
    newPlayerRegistration.Discipline = "Football";
    newPlayerRegistration.RegistrationNature = "Registration";
    newPlayerRegistration.Status = "Active";
    newPlayerRegistration.OrganisationFIFAId = organisationId;

    var newPersonRegistrations = new PersonRegistrationsType();
    newPersonRegistrations.PlayerRegistrations.Add(newPlayerRegistration);

    var request = new UpdateRegistrationsRequestType(personId,
        oldPersonRegistrations,
        newPersonRegistrations
    );

    try
    {
        var personType = await client.UpdateRegistrations(request, false).ConfigureAwait(false);
    }
    catch (ValidationException)
    {
        // provided data did not pass validation
    }
    catch(AuthenticationException ex)
    {
        // invalid client credentials
    }
    catch(UnauthorizedException ex)
    {
        // unauthorized
    }
    catch (InvalidClientDataException ex)
    {
        // data sent to the service was invalid
        var details = ex.BadRequestResponse;
    }
    catch (FifaEntityNotFoundException ex)
    {
        // could not find the person
        var operationResponse = ex.HttpOperationResponse;
    }
    catch (TooManyRequestsException ex)
    {
        // call rate limit was exceeded
        var retryAfterInSeconds = ex.RetryAfter;
    }
    catch (FifaConnectIdException ex)
    {
        // some error occurred, see the details
        var operationResponse = ex.HttpOperationResponse;
    }

Please note that each time an operation succeed, you will receive an object of class `PersonType` containing the current status of a person with all their registrations. This feature may be used for troubleshooting but also to synchronize the local data with a central DB (ID Directory).

Also note that errors are not thrown if you perform an operation which would result in the object not changing its state. For example, if you want to add a registration for a Football Player, Amateur in France, and such a registration already exists, error will not be thrown and the operation will succeed.

#### 3.2.7.3 Remove registrations

We do not provide SDK method for removing registrations. Correct operation here would be updating registration by setting its status to inactive (deactivation). If you are certain that a registration should be removed (e.g. it has been added by mistake), please contact our Helpdesk.

### 3.2.8 Updating a person

Note, that when updating the name of a person, you need to specify all pairs of names. For example if you originally registered a person with both local and international name, you need to specify both pairs even if you are changing only one name. Connect ID is only able to replace an existing set of names with a new set. The reason for this is personal data protection, which allows the service to store hashes but not names.

To update a person associated with the specified FIFA ID:

    try
    {
        var names = new List<PersonName>();
        names.Add(new PersonName("first name", "last name"));

        var updatedPerson = await client.UpdatePersonAsync("105C40T", names, new DateTime(1995, 01, 01), "male").ConfigureAwait(false);
    }
    catch (ValidationException)
    {
        // provided data did not pass validation
    }
    catch (AuthenticationException ex)
    {
        // invalid client credentials
        var details = ex.HttpOperationResponse;
    }
    catch (FifaDuplicateOfRegisteredPersonFoundException ex)
    {
        var duplicates = ex.GetDuplicatesResponseType.Duplicates;
        var registrationDate = ex.GetDuplicatesResponseType.RequestedPersonRegistrationContext.RegistrationDate;
    }
    catch (UnauthorizedException ex)
    {
        // unauthorized
        var details = ex.HttpOperationResponse;
    }
    catch (InvalidClientDataException ex)
    {
        // data sent to the service was invalid or the MA lacks permission to perform the operation
        var details = ex.BadRequestResponse;
    }
    catch (FifaEntityNotFoundException ex)
    {
        // could not find the person
        var operationResponse = ex.HttpOperationResponse;
    }
    catch (TooManyRequestsException ex)
    {
        // call rate limit was exceeded
        var retryAfterInSeconds = ex.RetryAfter;
    }
    catch (FifaConnectIdException ex)
    {
        // some error occurred, see the details
        var operationResponse = ex.HttpOperationResponse;
    }

### 3.2.9 Adding registrations handled by external system (SystemId)

By default, all registrations are stored in a single national registration system. It is however possible to connect additional system to FIFA Connect ID services. As an example we may consider the [main] national registration system being responsible for Amateur players only and an additional, external system – for Professionals. In such a setup it is important that Connect ID is able to properly route requests for player details sent by other MAs via Service Bus.

In order for this routing to work correctly, an external system, for each of registrations it manages (professional ones), must provide its unique identifier (System ID).

System ID can be set by using `SystemId` property. See below example:

    var organisationId = "105C8LX";
    var systemId = "105C8LX_SystemName";
    var newPlayerRegistration = new PlayerRegistrationType();

    newPlayerRegistration.Level = "Pro";
    newPlayerRegistration.Discipline = "Football";
    newPlayerRegistration.RegistrationNature = "Registration";
    newPlayerRegistration.Status = "Active";
    newPlayerRegistration.OrganisationFIFAId = organisationId;
    newPlayerRegistration.SystemId = systemId; // The system identifier is created and passed along with the access credentials.

There is no need of setting System ID if registration is added by a default system. In this case the `<null>` value should be used.

### 3.2.10 Bulk deactivating registrations

It is possible to bulk deactivate a set of given registrations using `BulkDeactivateRegistrations` method, which is available in `FifaConnectIdClient` class. As an input method takes a list of person registrations that will be deactivated. Only listed registrations will be deactivated - all other registrations that exist in the context of a given person will be left unchanged. Each registration needs to represent the current state (including status), otherwise server won't recognize it and will return error message that registration doesn't exist. One deactivation request can have up to 500 registrations in total (player, match official, team official and organisation official). Below you can find an example of bulk deactivation usage:

    var personsToDeactivate = new List<PersonDeactivateType>();

    try
    {
        //create a request based on a list of persons (e.g. taken from your database)
        foreach (var person in persons)
        {
            var personId = person.PersonId;
            var playerRegistrations = person.PlayerRegistrations;
            var teamOfficialRegistrations = person.TeamOfficialRegistrations;

            //You can take a subset of registrations that should be deactivated
            var playerRegistrationsToDeactivate = new List<PlayerRegistrationType>
            {
                playerRegistrations[0],
                playerRegistrations[2]
            };

            var teamOfficialRegistrationToDeactivate = new List<TeamOfficialRegistrationType>
            {
                teamOfficialRegistrations[3]
            };

            var personToDeactivate = new PersonDeactivateType(person.PersonId,
                new PersonRegistrationsType(playerRegistrationsToDeactivate,
                    // deactivate all Match Official Registrations
                    person.MatchOfficialRegistrations,
                    teamOfficialRegistrationToDeactivate,
                    //No organisation official registrations will be deactivated
                    new List<OrganisationOfficialRegistrationType>()));
        }

        var response = await client
            .BulkDeactivateRegistrations(new BulkDeactivateRegistrationsRequestType(personsToDeactivate))
            .ConfigureAwait(false);

        // Get persons for whom at least one registration has failed during deactivation
        var failedRegistrations = response.Results.Where(result => result.Success == false).ToList();
    }
    catch (ValidationException)
    {
        // provided data did not pass validation
    }
    catch (InvalidClientDataException ex)
    {
        // data sent to the service was invalid
        var details = ex.BadRequestResponse;
    }
    catch (TooManyRequestsException ex)
    {
        // call rate limit was exceeded
        var retryAfterInSeconds = ex.RetryAfter;
    }
    catch (FifaConnectIdException ex)
    {
        // some error occurred, see the details
        var operationResponse = ex.HttpOperationResponse;
    }

`BulkDeactivateRegistrations` method returns `BulkDeactivateRegistrationsResponseType`. It has property `Results`, which is an array of `BulkDeactivateRegistrationsResult`. Each instance of `BulkDeactivateRegistrationsResult` contains information about a status of specific person oriented operation. Possible properties are: `PersonId`, `Success`, `Exception`. In case when deactivation will fail for given person, `Success` will be set as `false` and additional information will be provided in `Exception`.

Please note that bulk deactivation is a heavy operation that affects server resources. Before running it please

- make sure that you notified Support Team (support.id@fifa.org), so we could scale up the system
- implement a retry logic in case of timeouts as bulk deactivation operation is idempotent

### 3.2.11 Data holders

Every member association that has or used to have a certain person's registration is known to be their DATA HOLDER. If Connect ID Service is aware of all data holders of a given FIFA_ID, it is able to properly build electronic player's passport and send notifications about data changes.

However, in some scenarios newly integrated MA may not be automatically registered as a data holder of a person. This will happen e.g. if they try to register an inactive player, they find a duplicate (because that player is active elsewhere) and simply store the FIFA_ID of a duplicate in their NRS. Connect ID Service will not be aware that MA just became a data holder of that person.

Therefore, an additional mechanism of data holding declaration had been introduced. MA can now claim to be a data holder of a given FIFA_ID and be included in the data holders list. To claim that your MA is person's data holder, `FifaConnectIdClient.RegisterAsDataHolderOfPerson` method should be called.

    try
    {
        await client.RegisterAsDataHolderOfPerson(personFifaId).ConfigureAwait(false);
    }
    catch (ValidationException)
    {
        // provided data did not pass validation
    }
    catch (AuthenticationException ex)
    {
        // invalid client credentials
        var details = ex.HttpOperationResponse;
    }
    catch (UnauthorizedException ex)
    {
        // unauthorized
        var details = ex.HttpOperationResponse;
    }
    catch (InvalidClientDataException ex)
    {
        // data sent to the service was invalid
        var details = ex.BadRequestResponse;
    }
    catch (FifaPersonMergedException ex)
    {
        // requested person has been merged
        var person = ex.RequestedEntity;
        var primaryPersonId = ex.PrimaryEntityId;
    }
    catch (FifaEntityNotFoundException ex)
    {
        // could not find the person
        var operationResponse = ex.HttpOperationResponse;
    }
    catch (FifaEntityDeletedException ex)
    {
        // person has been deleted
        var operationResponse = ex.HttpOperationResponse;
    }
    catch (FifaConnectIdException ex)
    {
        // some error occurred, see the details
        var operationResponse = ex.HttpOperationResponse;
    }

The method is idempotent i.e. can be called multiple times without any negative side-effects. It is important to note that the method only enqueues your registration request. The actual processing happens in the background. The implications are twofold: 1. The call will return as soon as the request is accepted. 2. It may take some time for the system to process the request

In order to confirm that your request has been processed, you can call another method `FifaConnectIdClient.GetDataHoldersOfPerson(string personFifaId)` which returns the list of systems who are Data Holders of the given person FIFA_ID. After successful processing, the list should contain your NRS' ID. However, it is not recommended to call it after every call to `RegisterAsDataHolderOfPerson`.

## 3.3 Sharing Person's details with any system over the Service Bus

You can share the details of any person with another system over the Service Bus. It is important for you to agree on the message type that will be used both by the sender and the recipient.

### 3.3.1 Sending PersonLocal object

You can send a PersonLocal object to any system using an instance of `PersonLocalSender`. Please note that the `messageType` argument has be to agreed with the receiving system so that they can register a handler for it. You can find more information on the subject in our portal.

    var xsdFilesResolver = new XsdSchemasDirectoryResolver(@"C:\custom\directory\where\scenarios.xsd\is\located");
    var personLocalSender = new PersonLocalSender(registrationfacade.ServiceBusClient, xsdFilesResolver);

    var recipient = "105C3ZB_CSRS";
    var messageType = "expected-message-type";
    var personLocal = new PersonLocal("ΧΑΡΑΛΑΜΠΟΥΣ", Gender.Male, ISO3166CountryCode.CY,
        new DateTime(1990, 11, 11), ISO316613CountryCode.CY, "Larnaca", ISO6392LanguageCode.Gre,
        ISO3166CountryCode.CY, "105C3Z1");

    try
    {
        await personLocalSender.SendAsync(personLocal, recipient, messageType).ConfigureAwait(false);
    }
    catch (XmlSerializationException ex)
    {
        // handle serialization exception
    }
    catch (ValidationException ex)
    {
        // provided data did not pass validation
    }
    catch (AuthenticationException ex)
    {
        // invalid client credentials
        var details = ex.HttpOperationResponse;
    }
    catch (InvalidClientDataException ex)
    {
        // data sent to the service was invalid
        var details = ex.BadRequestResponse;
    }
    catch (QueueNotFoundException ex)
    {
        // invalid recipient
    }
    catch (UnauthorizedException ex)
    {
        // unauthorized
        var details = ex.HttpOperationResponse;
    }
    catch (FifaConnectIdException ex)
    {
        // some error occurred, see the details
        var operationResponse = ex.HttpOperationResponse;
    }

### 3.3.2 Receiving PersonLocal object

In order to receive Person's details sent by another system over the Service Bus (according to section 3.3.1) you need to register an extra message handler for the agreed message type. Our SDK will take care of validation and deserialization of the message.

All you need to provide is an implementation of your own handler that will be invoked when the PersonLocal object is received.

    using Fifa.ConnectId.Sdk.Core.XmlParser.DataStandard;
    using Fifa.ConnectId.Sdk.MessageHandlers;

    public class PersonLocalReceivedHandler : IPersonLocalReceivedHandler
    {
        public void Handle(PersonLocal personLocal, string sender)
        {
            // TODO: implement handle() method.
        }
    }

When configuring the Listener add an extra message handler:

    var personLocalReceivedHandler = new PersonLocalReceivedHandler();
    var messageType = "expected-message-type";
    var personLocalMessageHandler = new PersonLocalMessageHandler(personLocalReceivedHandler, messageType, xsdFilesResolver);

    // add new message handlers to the collection of existing ones
    messageHandlers.Add(personLocalMessageHandler);

    registrationfacade.ConfigureListener(personDetailsProvider, messageHandlers, cleanJob);

# 4.Organisation

## 4.1 Registering an organisation

To register a new organisation:

    var organisation = new OrganisationLocalType
    {
        Status = "active",
        OrganisationNature = "WorldFederation",
        // fill up all required data according to FIFA Data Standard
    };

    try
    {
        var uniqueFifaId = await client.RegisterOrganisationAsync(organisation).ConfigureAwait(false);
    }
    catch (ValidationException)
    {
        // provided data did not pass validation
    }
    catch (AuthenticationException)
    {
        // invalid client credentials
    }
    catch (UnauthorizedException)
    {
        // unauthorized
    }
    catch (InvalidClientDataException ex)
    {
        // data sent to the service was invalid
        var details = ex.BadRequestResponse;
    }
    catch (FifaDuplicatedOrganisationFoundException ex)
    {
        // possible duplicates were found
        var duplicates = ex.GetOrganisationDuplicatesResponse.Duplicates;
    }
    catch (TooManyRequestsException ex)
    {
        // call rate limit was exceeded
        var retryAfterInSeconds = ex.RetryAfter;
    }
    catch (FifaConnectIdException ex)
    {
        // some other error occurred, see the details
        var operationResponse = ex.HttpOperationResponse;
    }

If duplicated organisation is found then `FifaDuplicatedOrganisationFoundException` will be thrown. In order to resolve conflict and register new organisation use optional `force` parameter as presented below:

    bool force = true;
    string organisationFifaId = await client.RegisterOrganisationAsync(organisation, force).ConfigureAwait(false);

## 4.2 Getting organisation data

To get the organisation data associated with the specified FIFA ID use `GetOrganisationAsync` method. This method will throw `FifaOrganisationMergedException` when you try to get data for an organisation that has been previously merged and deactivated (refer to section "Merging organisations"). The exception will contain data about requested organisation together with primary organisation id.

    try
    {
        var uniqueFifaId = "BVGE8TG";
        var organisation = await client.GetOrganisationAsync(uniqueFifaId).ConfigureAwait(false);
    }
    catch (ValidationException)
    {
        // provided data did not pass validation
    }
    catch (AuthenticationException ex)
    {
        // invalid client credentials
        var response = ex.HttpOperationResponse;
    }
    catch (UnauthorizedException ex)
    {
        // unauthorized
        var response = ex.HttpOperationResponse;
    }
    catch (InvalidClientDataException ex)
    {
        // data sent to the service was invalid
        var details = ex.BadRequestResponse;
    }
    catch (FifaEntityNotFoundException ex)
    {
        // could not find the organisation
        var operationResponse = ex.HttpOperationResponse;
    }
    catch (FifaOrganisationMergedException ex)
    {
        // requested organisation has been merged and is inactive
        var organisation = ex.RequestedEntity;
        var primaryOrganisationId = ex.PrimaryEntityId;
    }
    catch (TooManyRequestsException ex)
    {
        // call rate limit was exceeded
        var retryAfterInSeconds = ex.RetryAfter;
    }
    catch (FifaConnectIdException ex)
    {
        // some error occurred, see the details
        var operationResponse = ex.HttpOperationResponse;
    }

## 4.3 Merging/unmerging organisations

To merge two organisations into a single one use `MergeOrganisationsAsync` method available on `FifaConnectIdClient`. This operation will only work for clubs. In addition you can only merge those that belong to the same member association that you are a member of. As a result of this operation, secondary organisation status will be set to `inactive`. This affects getting secondary organisation data in the future. Please refer to section 4.2 Getting organisation data. Here is an example how to merge organisations:

    try
    {
        var organisation = await client.MergeOrganisationsAsync(primaryOrganisationId, secondaryOrganisationId).ConfigureAwait(false);
    }
    catch (ValidationException)
    {
        // provided data did not pass validation
    }
    catch (AuthenticationException ex)
    {
        // invalid client credentials
        var details = ex.HttpOperationResponse;
    }
    catch (UnauthorizedException ex)
    {
        // unauthorized
        var details = ex.HttpOperationResponse;
    }
    catch (InvalidClientDataException ex)
    {
        // data sent to the service was invalid
        var details = ex.BadRequestResponse;
    }
    catch (FifaConflictException ex)
    {
        // a conflicting operation is currently in progress
        var details = ex.Response;
    }
    catch (FifaEntityNotFoundException ex)
    {
        // could not find one of specified organisations
        var operationResponse = ex.HttpOperationResponse;
    }
    catch (TooManyRequestsException ex)
    {
        // call rate limit was exceeded
        var retryAfterInSeconds = ex.RetryAfter;
    }
    catch (FifaConnectIdException ex)
    {
        // some error occurred, see the details
        var operationResponse = ex.HttpOperationResponse;
    }

In order to revert merge operation call `UnmergeOrganisationsAsync` method with the same arguments.

## 4.4 Updating an organisation

To update the organisation data use `UpdateOrganisationAsync` method.

    try
    {
        var organisationId = "BVGE8TG";
        var organisation = await client.GetOrganisationAsync(organisationId).ConfigureAwait(false);

        // modify data
        organisation.Status = "inactive";
        organisation.Email = "some@other.email";

        var updatedOrganisation = await client.UpdateOrganisationAsync(organisation).ConfigureAwait(false);
    }
    catch (ValidationException)
    {
        // provided data did not pass validation
    }
    catch (AuthenticationException ex)
    {
        // invalid client credentials
        var details = ex.HttpOperationResponse;
    }
    catch (UnauthorizedException ex)
    {
        // unauthorized
        var details = ex.HttpOperationResponse;
    }
    catch (InvalidClientDataException ex)
    {
        // data sent to the service was invalid
        var details = ex.BadRequestResponse;
    }
    catch (FifaEntityNotFoundException ex)
    {
        // could not find the organisation
        var operationResponse = ex.HttpOperationResponse;
    }
    catch (FifaDuplicatedOrganisationFoundException ex)
    {
        // possible duplicates were found
        var duplicates = ex.GetOrganisationDuplicatesResponse.Duplicates;
    }
    catch (TooManyRequestsException ex)
    {
        // call rate limit was exceeded
        var retryAfterInSeconds = ex.RetryAfter;
    }
    catch (FifaConnectIdException ex)
    {
        // some error occurred, see the details
        var operationResponse = ex.HttpOperationResponse;
    }

If duplicated organisation is found then `FifaDuplicatedOrganisationFoundException` will be thrown. In order to resolve conflict and update organisation use optional `force` parameter.

## 4.5 Searching for an organisation

### 4.5.1 Search using 'FindOrganisations' method

It takes `FindOrganisationsRequestType` as a parameter that aggregates search criteria. It's possible to search by international and local names, parent organisation, organisation nature, address and last modification date. This method takes into consideration date and time when making a query using `ModifiedFromDateTime` and `ModifiedToDateTime`.

    try
    {
        var request = new FindOrganisationsRequestType
        {
            InternationalName = "Barcelona",
            ModifiedFromDateTime = DateTime.UtcNow.AddDays(-5),
            ModifiedToDateTime = DateTime.UtcNow,
            OfficialAddress = new SearchAddressType
            {
                Country = "ES",
                Town = "Barcelona"
            },
            NumberOfResults = 5
        };

        var client = facade.ConnectIdClient;
        var response = await client.FindOrganisations(request).ConfigureAwait(false);
        var foundOrganisations = response.Organisations;
    }
    catch (ValidationException)
    {
        // provided data did not pass validation
    }
    catch (AuthenticationException ex)
    {
        // invalid client credentials
        var details = ex.HttpOperationResponse;
    }
    catch (UnauthorizedException ex)
    {
        // unauthorized
        var details = ex.HttpOperationResponse;
    }
    catch (TooManyRequestsException ex)
    {
        // call rate limit was exceeded
        var retryAfterInSeconds = ex.RetryAfter;
    }
    catch (InvalidClientDataException ex)
    {
        // data sent to the service was invalid
        var details = ex.BadRequestResponse;
    }

## 4.6 Get organisation duplicates

To get a list of duplicates for an organisation use `GetOrganisationDuplicatesAsync` method. This method looks for similar organisations already registered in FIFA Connect ID Service.

    try
    {
        var organisation = new OrganisationLocalType
        {
            Status = "active",
            InternationalName = "Organisation name",
            OrganisationNature = "Club",
            // fill up all required data according to FIFA Data Standard
        };

        var foundDuplicates = await client.GetOrganisationDuplicatesAsync(organisation).ConfigureAwait(false);
    }
    catch (ValidationException)
    {
        // provided data did not pass validation
    }
    catch (AuthenticationException ex)
    {
        // invalid client credentials
        var details = ex.HttpOperationResponse;
    }
    catch (UnauthorizedException ex)
    {
        // unauthorized
        var details = ex.HttpOperationResponse;
    }
    catch (InvalidClientDataException ex)
    {
        // data sent to the service was invalid
        var details = ex.BadRequestResponse;
    }
    catch (TooManyRequestsException ex)
    {
        // call rate limit was exceeded
        var retryAfterInSeconds = ex.RetryAfter;
    }
    catch (FifaConnectIdException ex)
    {
        // some error occurred, see the details
        var operationResponse = ex.HttpOperationResponse;
    }

## 4.7 Get National Associations onboarded status

To get a list with onboarded statuses (has any persons or suborganisations registered) for specific National Associations use `GetNationalAssociationsOnboardedStatus` method. It takes `NationalAssociationsOnboardedRequestType` as a parameter which should contain list of strings with National Associations FIFA IDs.

    try
    {
        var request = new NationalAssociationsOnboardedRequestType{
            NationalAssociationsFifaIds = new List<string>{"BVGE8TG","AHAR8SV"}
        };
        var response = await client.GetNationalAssociationsOnboardedStatus(request).ConfigureAwait(false);
    }
    catch (ValidationException)
    {
        // provided data did not pass validation
    }
    catch (AuthenticationException ex)
    {
        // invalid client credentials
        var details = ex.HttpOperationResponse;
    }
    catch (UnauthorizedException ex)
    {
        // unauthorized
        var details = ex.HttpOperationResponse;
    }
    catch (InvalidClientDataException ex)
    {
        // data sent to the service was invalid
        var details = ex.BadRequestResponse;
    }
    catch (FifaEntityNotFoundException ex)
    {
        // could not find the organisation
        var operationResponse = ex.HttpOperationResponse;
    }
    catch (TooManyRequestsException ex)
    {
        // call rate limit was exceeded
        var retryAfterInSeconds = ex.RetryAfter;
    }
    catch (FifaConnectIdException ex)
    {
        // some error occurred, see the details
        var operationResponse = ex.HttpOperationResponse;
    }

To get a list with onboarded statuses for all National Associations use `GetAllNationalAssociationsOnboardedStatus` method.

    try
    {
        var response = await client.GetAllNationalAssociationsOnboardedStatus().ConfigureAwait(false);
    }
    catch (AuthenticationException ex)
    {
        // invalid client credentials
        var details = ex.HttpOperationResponse;
    }
    catch (UnauthorizedException ex)
    {
        // unauthorized
        var details = ex.HttpOperationResponse;
    }
    catch (TooManyRequestsException ex)
    {
        // call rate limit was exceeded
        var retryAfterInSeconds = ex.RetryAfter;
    }
    catch (FifaConnectIdException ex)
    {
        // some error occurred, see the details
        var operationResponse = ex.HttpOperationResponse;
    }

## 4.8 Get Member Association of a child organisation (e.g. a club)

Some MAs (Member Associations) may have a multi-level structure of children organisations, e.g. teams, clubs, schools, regions, etc. In many cases, however, there is a need to find out to which MA a given organisation (e.g. a club) belongs to. To get FIFA ID and short name of that MA use `GetMemberAssociationForFifaId` method with the organisation's FIFA ID as input.

Note, that in order to retrieve the full name of the MA, call `GetOrganisationAsync` passing FIFA ID of the MA.

    try
    {
        var uniqueFifaId = "BVGE8TG";
        var memberAssociation = await client.GetMemberAssociationForFifaId(uniqueFifaId).ConfigureAwait(false);
    }
    catch (FifaEntityNotFoundException ex)
    {
        // could not find the memberAssociation
        var operationResponse = ex.HttpOperationResponse;
    }
    catch (InvalidClientDataException ex)
    {
        // provided organisation id is not valid
        var details = ex.BadRequestResponse;
    }
    catch (FifaConnectIdException ex)
    {
        // some error occurred, see the details
        var operationResponse = ex.HttpOperationResponse;
    }
    catch (AuthenticationException ex)
    {
        // invalid client credentials
        var response = ex.HttpOperationResponse;
    }
    catch (UnauthorizedException ex)
    {
        // unauthorized
        var response = ex.HttpOperationResponse;
    }
    catch (TooManyRequestsException ex)
    {
        // call rate limit was exceeded
        var retryAfterInSeconds = ex.RetryAfter;
    }
    catch (ValidationException)
    {
        // provided data did not pass validation
    }

# 5. Facility

## 5.1 Registering a facility

To register a new facility:

    var facility = new FacilityLocalType()
    {
        Status = "active",
        InternationalName = "Wembley Stadium",
        OrganisationFIFAId = "BVGE8TG"
        // fill up all required data according to FIFA Data Standard
    };

    try
    {
        var uniqueFifaId = await client.RegisterFacilityAsync(facility).ConfigureAwait(false);
    }
    catch (ValidationException)
    {
        // provided data did not pass validation
    }
    catch (AuthenticationException ex)
    {
        // invalid client credentials
    }
    catch (UnauthorizedException ex)
    {
        // unauthorized
    }
    catch (InvalidClientDataException ex)
    {
        // data sent to the service was invalid
        var details = ex.BadRequestResponse;
    }
    catch (FifaDuplicatedFacilityFoundException ex)
    {
        // possible duplicates were found
        var duplicates = ex.GetFacilityDuplicatesResponse.Duplicates;
    }
    catch (TooManyRequestsException ex)
    {
        // call rate limit was exceeded
        var retryAfterInSeconds = ex.RetryAfter;
    }
    catch (FifaConnectIdException ex)
    {
        // some other error occurred, see the details
        var operationResponse = ex.HttpOperationResponse;
    }

If duplicated facility is found then `FifaDuplicatedFacilityFoundException` will be thrown. In order to resolve conflict and register new facility use optional `force` parameter.

## 5.2 Getting facility data

To get the facility data associated with the specified FIFA ID:

    try
    {
        var uniqueFifaId = "105C40T";
        var facility = await client.GetFacilityAsync(uniqueFifaId).ConfigureAwait(false);
    }
    catch (ValidationException)
    {
        // provided data did not pass validation
    }
    catch(AuthenticationException ex)
    {
        // invalid client credentials
    }
    catch(UnauthorizedException ex)
    {
        // unauthorized
    }
    catch (InvalidClientDataException ex)
    {
        // data sent to the service was invalid
        var details = ex.BadRequestResponse;
    }
    catch (FifaEntityNotFoundException ex)
    {
        // could not find the facility
        var operationResponse = ex.HttpOperationResponse;
    }
    catch (TooManyRequestsException ex)
    {
        // call rate limit was exceeded
        var retryAfterInSeconds = ex.RetryAfter;
    }
    catch (FifaConnectIdException ex)
    {
        // some error occurred, see the details
        var operationResponse = ex.HttpOperationResponse;
    }

## 5.3 Updating a facility

To update the facility data use `UpdateFacilityAsync` method.

    try
    {
        var facilityId = "105C40T";
        var facility = await client.GetFacilityAsync(facilityId).ConfigureAwait(false);

        // set the data to update
        facility.Email = "some@other.email";
        facility.Status = "inactive";

        var updatedFacility = await client.UpdateFacilityAsync(facility).ConfigureAwait(false);
    }
    catch (ValidationException)
    {
        // provided data did not pass validation
    }
    catch (AuthenticationException ex)
    {
        // invalid client credentials
        var details = ex.HttpOperationResponse;
    }
    catch (UnauthorizedException ex)
    {
        // unauthorized
        var details = ex.HttpOperationResponse;
    }
    catch (InvalidClientDataException ex)
    {
        // data sent to the service was invalid
        var details = ex.BadRequestResponse;
    }
    catch (FifaEntityNotFoundException ex)
    {
        // could not find the facility
        var operationResponse = ex.HttpOperationResponse;
    }
    catch (FifaDuplicatedFacilityFoundException ex)
    {
        // possible duplicates were found
        var duplicates = ex.GetFacilityDuplicatesResponse.Duplicates;
    }
    catch (TooManyRequestsException ex)
    {
        // call rate limit was exceeded
        var retryAfterInSeconds = ex.RetryAfter;
    }
    catch (FifaConnectIdException ex)
    {
        // some error occurred, see the details
        var operationResponse = ex.HttpOperationResponse;
    }

If duplicated facility is found then `FifaDuplicatedFacilityFoundException` will be thrown. In order to resolve conflict and update facility use optional `force` parameter.

## 5.4 Searching for a facility

To search for a facility use `FindFacilities` method. It takes `FindFacilitiesRequestType` as a parameter that aggregates search criteria. It's possible to search by international and local names, parent facility, organisation, and address.

    try
    {
        var request = new FindFacilitiesRequestType
        {
            InternationalName = "Camp Nou",
            ModifiedFromDateTime = DateTime.UtcNow.AddDays(-5),
            ModifiedToDateTime = DateTime.UtcNow,
            OfficialAddress = new SearchAddressType
            {
                Country = "ES",
                Town = "Barcelona"
            },
            NumberOfResults = 5
        };

        var response = await client.FindFacilities(request).ConfigureAwait(false);
        var foundFacilities = response.Facilities;
    }
    catch (ValidationException)
    {
        // provided data did not pass validation
    }
    catch (AuthenticationException ex)
    {
        // invalid client credentials
        var details = ex.HttpOperationResponse;
    }
    catch (UnauthorizedException ex)
    {
        // unauthorized
        var details = ex.HttpOperationResponse;
    }
    catch (TooManyRequestsException ex)
    {
        // call rate limit was exceeded
        var retryAfterInSeconds = ex.RetryAfter;
    }
    catch (InvalidClientDataException ex)
    {
        // data sent to the service was invalid
        var details = ex.BadRequestResponse;
    }

## 5.5 Get facility duplicates

To get a list of duplicates for a facility use `GetFacilityDuplicatesAsync` method. This method looks for similar facilities already registered in FIFA Connect ID service.

    try
    {
        var facility = new FacilityLocalType
        {
            Status = "active",
            InternationalName = "Facility name",
            // fill up all required data according to FIFA Data Standard
        };

        var foundDuplicates = await client.GetFacilityDuplicatesAsync(facility).ConfigureAwait(false);
    }
    catch (ValidationException)
    {
        // provided data did not pass validation
    }
    catch (AuthenticationException ex)
    {
        // invalid client credentials
        var details = ex.HttpOperationResponse;
    }
    catch (UnauthorizedException ex)
    {
        // unauthorized
        var details = ex.HttpOperationResponse;
    }
    catch (InvalidClientDataException ex)
    {
        // data sent to the service was invalid
        var details = ex.BadRequestResponse;
    }
    catch (TooManyRequestsException ex)
    {
        // call rate limit was exceeded
        var retryAfterInSeconds = ex.RetryAfter;
    }
    catch (FifaConnectIdException ex)
    {
        // some error occurred, see the details
        var operationResponse = ex.HttpOperationResponse;
    }

# 6. [Optional] Transfer Matching System (TMS) integration

This chapter is directed only to MAs who have TMS integration in their scope. Please note, that this chapter focuses on the technical implementation only and does not give details about business scenarios that different methods should be used in. For the latter, check our support portal.

## 6.1 Create TMS facade

In order to integrate with TMS, you need to instantiate a dedicated facade object that will serve as an entry point for all TMS-related operations.

    var serviceBusClient = registrationFacade.ServiceBusClient;
    ILogger logger = new YourOwnLogger();
    ICachePollingResponseAwaitersFactory responseAwaiterFactory = new CachePollingResponseAwaitersFactory();
    var responsesCache = new CorrelationIdBasedInMemoryCache<MessageReceived>(TimeSpan.FromMinutes(10));

    TmsFacade tmsFacade = new TmsFacade(serviceBusClient, logger, responseAwaiterFactory, responsesCache);

### 6.1.1 Configure listener

TMS Facade relies on the registration facade for listening for incoming reponses from TMS. In order to hook TMS facade into the existing listener infrastruture, you add a new argument to the current `configureListener` call:

    var tmsMessageHandlers = TmsFacadeHandlersFactory.CreateMessageHandlers(responsesCache);
    registrationFacade.ConfigureListener(personDetailsProvider, tmsMessageHandlers);

### 6.1.2 Advanced configuration

When running the listener in a separate process, you need to provide a shared storage for incoming confirmation messages. For more information on the subject please refer to section 3.1.8 Advanced listener configuration. Below are the interfaces that need to be implemented: - `ICorrelationIdBasedItemProvider<MessageReceived>` - Used by the TMS facade to get records from shared storage by id. If there is no entry associated with the given id, `null` value should be returned - `ICorrelationIdBasedItemContainer<MessageReceived>` - Used by the TMS message handlers factory to put records into the shared storage

An implementation stub:

    public class DomesticTransferConfirmationSharedStorage :
        ICorrelationIdBasedItemContainer<MessageReceived>,
        ICorrelationIdBasedItemProvider<MessageReceived>
    {
        public void Put(string correlationId, MessageReceived itemToCache)
        {
            throw new NotImplementedException();
        }

        public MessageReceived GetByCorrelationId(string correlationId)
        {
            throw new NotImplementedException();
        }
    }

## 6.2 Add person to TMS

In order to add a person to TMS, you need to build a `PersonLocal` object and pass it to `AddPlayer` method. `PersonLocal` type is compliant with FIFA Data Standard.

    var personLocal = new PersonLocal(
        "ΧΑΡΑΛΑΜΠΟΥΣ", Gender.Male, ISO3166CountryCode.CY, new DateTime(1990, 11, 11)ISO316613CountryCode.CY,
        "Larnaca", ISO6392LanguageCode.Gre, ISO3166CountryCode.CY, "1XDZR79");
    try
    {
        string correlationId = await tmsFacade.AddPlayer(personLocal).ConfigureAwait(false);
    }
    catch (TmsOperationException ex)
    {
        // issue occurred during TMS operation
        var details = ex.InnerException;
    }

Notice that in this scenario you don't wait for TMS to answer. `correlationId` does not prove that the message has been picked up by TMS, only that it has been successfully sent. Although `correlationId` is not required for any further processing, we recommend that you log it.

## 6.3 Update person in TMS

In order to update a person to TMS, you need to build a `PersonLocal` object and pass it to `UpdatePlayer` method. `PersonLocal` type is compliant with FIFA Data Standard.

    var personLocal = new PersonLocal(
        "ΧΑΡΑΛΑΜΠΟΥΣ", Gender.Male, ISO3166CountryCode.CY, new DateTime(1990, 11, 11)ISO316613CountryCode.CY,
        "Larnaca", ISO6392LanguageCode.Gre, ISO3166CountryCode.CY, "1XDZR79");
    try
    {
        string correlationId = await tmsFacade.UpdatePlayer(personLocal).ConfigureAwait(false);
    }
    catch (TmsOperationException ex)
    {
        // issue occurred during TMS operation
        var details = ex.InnerException;
    }

Notice that in this scenario you don't wait for TMS to answer. `correlationId` does not prove that the message has been picked up by TMS, only that it has been successfully sent. Although `correlationId` is not required for any further processing, we recommend that you log it.

## 6.4 Send Domestic Transfer Declaration

Sending a declaration is fairly straightforward:

    //create person local
    var personFifaId = "1XDZR79";
    var personLocal = new PersonLocal(
    "ΧΑΡΑΛΑΜΠΟΥΣ", Gender.Male, ISO3166CountryCode.CY, new DateTime(1990, 11, 11), ISO316613CountryCode.CY,
    "Larnaca", ISO6392LanguageCode.Gre, ISO3166CountryCode.CY, personFifaId
    );

    //add player registration
    personLocal.AddPlayerRegistration(new PlayerRegistration(
    personFifaId,
    Status.Active,
    "103C3AB",
    new DateTime(2020,10,10),
    RegistrationLevel.Pro,
    Discipline.Football,
    PlayerRegistrationNature.Registration ));

    //create declaration
    var engagingClub = new Club("ARZI7RL", "Q8ZZ8RT", "Engaging Club International Name");
    var releasingClub = new Club("HNIUE01", "SW8FJ2P", "Releasing Club International Name");
    var playerLevelInEngagingClub = RegistrationLevel.Pro;
    var playerLevelInReleasingClub = RegistrationLevel.Amateur;
    var messageId = "Information uniquely identifying this particular declaration";
    var sellOnFee = SellOnFee.No; // if no information is available, set to SellOnFee.NotAvailable
    var declaration = new DomesticTransferDeclaration(messageId, personLocal, engagingClub, releasingClub,
    new DateTime(2027, 11, 11), playerLevelInEngagingClub, playerLevelInReleasingClub, TransferNature.Permanent, sellOnFee);

    //add conditional transfer fees
    var recipientClub = new Club("HNIUE01", "SW8FJ2P", "Transfer Fee Club International Name");

    var conditionalTransferFeeDetails = new TransferFeeDetails(156, ISO4217CurrencyCode.AED, new DateTime(2020, 1, 1), recipientClub);
    declaration.AddConditionalTransferFee(new ConditionalTransferFee(conditionalTransferFeeDetails)
    {
    Condition = "specify condition"
    });

    //add fixed transfer fees

    //add release buyout transfer fees

    //populate the declaration with data

    try
    {
    long tmsTransferId = await tmsFacade
        .DeclareDomesticTransferAndWaitForTransferId(declaration, TimeSpan.FromSeconds(60))
        .ConfigureAwait(false);
    }
    catch (TmsOperationException operationException)
    {
    // Errors when trying to send message to TMS. Check inner exception for details
    var details = operationException.Message;
    var innerException = operationException.InnerException;
    }
    catch (DeclarationRejectedException declarationRejectedException)
    {
    // TMS rejected the declaration. See the reason for details:
    var rejectionReason = declarationRejectedException.Reason;
    }
    catch (ResponseNotReceivedException ex)
    {
    // Possible reasons:
    // 1. TMS has not responded within the timeout (consider increasing the timeout)
    // 2. responsesCache is not populated by the listener (see section 6.1.1)
    var details = ex.Message;
    }
    catch (Exception ex)
    {
    // Something else went wrong
    var details = ex.Message;
    }

TMS facade sends the declaration to the Service Bus. TMS is expected to read the declaration and send a Domestic Transfer Confirmation back with a TMS Transfer ID. The facade waits for a given period of time for the response. Should the response not arrive, ResponseNotReceivedException exception is thrown. Once the confirmation is received you have to store the `tmsTransferId`. It will be required for sending Proof Of Payment message later on. Should TMS consider the request invalid, `DeclarationRejectedException` will be thrown with a message from TMS providing the reason of the rejection.

## 6.5 Send Proof of Payment

In order to send a Proof of Payment to TMS, you need to build a `ProofOfPayment` object and pass it to `ProvePaymentAndWaitForPaymentId` method. Please mind that all properties are obligatory.

    var paymentDetails = new PaymentDetails(156, ISO4217CurrencyCode.AED, new DateTime(2020, 1, 1));
    var club = new Club("105KYBB", "105C6FI", "Organisation name");
    var messageId = "Information uniquely identifying this particular payment, e.g. bank transfer id";

    var proofOfPayment = new ProofOfPayment(messageId, PaymentType.FixedTransferFee, 1234, paymentDetails, club);

    try
    {
        long tmsPaymentId = await tmsFacade
            .ProvePaymentAndWaitForPaymentId(proofOfPayment, TimeSpan.FromSeconds(60))
            .ConfigureAwait(false);
    }
    catch (TmsOperationException operationException)
    {
        // Errors when trying to send message to TMS. Check inner exception for details
        var details = operationException.Message;
        var innerException = operationException.InnerException;
    }
    catch (DeclarationRejectedException declarationRejectedException)
    {
        // TMS rejected the declaration. See the reason for details:
        var rejectionReason = declarationRejectedException.Reason;
    }
    catch (ResponseNotReceivedException ex)
    {
        // Possible reasons:
        // 1. TMS has not responded within the timeout (consider increasing the timeout)
        // 2. responsesCache is not populated by the listener (see section 6.1.1)
        var errorDetails = ex.Message;
    }
    catch (Exception ex)
    {
        // Something else went wrong
        var errorDetails = ex.Message;
    }

TMS facade sends the proof to the Service Bus. TMS is expected to read the proof and send a Proof Of Payment Confirmation back with a TMS Payment ID. The facade waits for a given period of time for the response. Should the response not arrive, `ResponseNotReceivedException` exception is thrown. Should TMS consider the request invalid, `DeclarationRejectedException` will be thrown with a message from TMS providing the reason of the rejection. As of August 2020 there is no requirement to store `tmsPaymentId`. We recommend you log it as a confirmation that the message has been sent & received successfully.

## 6.6 Send First Pro Registration

Sending a registration is fairly straightforward:

    var personLocal = new PersonLocal(
        "ΧΑΡΑΛΑΜΠΟΥΣ", Gender.Male, ISO3166CountryCode.CY, new DateTime(1990, 11, 11), ISO316613CountryCode.CY,
        "Larnaca", ISO6392LanguageCode.Gre, ISO3166CountryCode.CY, "1XDZR79"
    );
    var proRegistration = new PlayerRegistration(
        "1XDZR79", Status.Active, "105C6FI", new DateTime(2021, 03, 31),
        RegistrationLevel.Pro, Discipline.Football, PlayerRegistrationNature.Registration
    );
    personLocal.PlayerRegistration.Add(proRegistration);

    var club = new Club("105KYBB", "105C6FI", "Organisation name");
    var messageId = "Information uniquely identifying this particular registration";
    var firstProRegistration = new FirstProRegistration(messageId, personLocal, club, ClubStatus.Active, true);
    try
    {
        long tmsFirstRegistrationId = await tmsFacade
            .DeclareFirstProRegistrationAndWaitForRegistrationId(firstProRegistration, TimeSpan.FromSeconds(60))
            .ConfigureAwait(false);
    }
    catch (TmsOperationException operationException)
    {
        // Errors when trying to send message to TMS. Check inner exception for details
        var details = operationException.Message;
        var innerException = operationException.InnerException;
    }
    catch (DeclarationRejectedException declarationRejectedException)
    {
        // TMS rejected the declaration. See the reason for details:
        var rejectionReason = declarationRejectedException.Reason;
    }
    catch (ResponseNotReceivedException ex)
    {
        // Possible reasons:
        // 1. TMS has not responded within the timeout (consider increasing the timeout)
        // 2. responsesCache is not populated by the listener (see section 6.1.1)
        var details = ex.Message;
    }
    catch (Exception ex)
    {
        // Something else went wrong
        var details = ex.Message;
    }

# 7. [Optional] Automatic notifications

Certain business operations in FIFA Connect ID trigger notifications. For each notification type a subscription can be created, so that when a notification is triggered, then a message is sent out. Two message types are supported: email & service bus. For the complete business documentation, list of notification types and methods to subscribe, please refer to Connect ID Notifications article.

In order to subscribe for a particular notification type, please get in touch with support.

Service bus messages are particularly interesting in the context of the SDK as it enables receiving them in an automated way. Under the hood, a service bus notification message is an XML document exchanged via the service bus infrastructure. The SDK handles the XML deserialization & validation and exposes an extension point you can hook into in order to process the message.

In order to use notification messages in your system, you need to implement an interface defined by the SDK and configure the listener to handle the messages.

## 7.1 Configuring listener

In order to take advantage of notifications, additional message handlers must be added when configuring the listener. Custom business logic can be invoked by implementing a notification handler interface and passing it as a constructor paramerter to the corresponding message handler.

A stub implementation of a custom notification message handler:

    public class CustomPersonMergedNotificationHandler : IPersonMergedNotificationHandler
    {
        public void Execute(PersonMergedNotification personMergedNotification)
        {
            throw new NotImplementedException();
        }
    }

The example below assumes that TMS integration is implemented:

    var tmsHandlers = TmsFacadeHandlersFactory.CreateMessageHandlers(responsesCache);
    var notificationHandlers = new List<IMessageHandler>
    {
        //list of notification message handlers
        new PersonMergedMessageHandler(new CustomPersonMergedNotificationHandler()),
        new PersonNameChangedMessageHandler(new CustomPersonNameChangedNotificationHandle()),
        new DateOfBirthChangedMessageHandler(new CustomDateOfBirthChangedNotificationHandler()),
        new GenderChangedMessageHandler(new CustomGenderChangedNotificationHandler())
    };
    var messageHandlers = tmsHandlers.Concat(notificationHandlers);
    registrationFacade.ConfigureListener(personDetailsProvider, messageHandlers);

## 7.2 PersonMergedNotification

This notification is created when a person ("secondary") is merged into another person ("primary"). The secondary person FIFA ID is no longer active. With this notification message you can automate the process of updating your data. If you store any data for the secondary person, after the merge, you should replace the secondary person FIFA ID with the primary person FIFA ID in your NRS.

### 7.2.1 Contents

The message contains the following information:

- Primary Person FIFA ID - Primary FIFA ID from the respective merge operation
- Secondary Person FIFA ID - Secondary FIFA ID from the respective merge operation
- Actor Name - Who performed the merge operation
- Operation Timestamp - When the merge operation was performed

### 7.2.2 Handler interface

SDK exposes `IPersonMergedNotificationHandler` interface which can be used to process a notification, e.g. update the FIFA ID in an internal NRS' database.

## 7.3 PersonNameChangedNotification

This notification is created when a change of a person name is made using update. If you store any data for the person, after the change, you might want to update a record in your DB. Due to the fact that ConnectId does not store user name, there is no information on what was the name before and after a change. To get new data of the modified record you can concact the NRS that triggered the notification.

### 7.3.1 Contents

The message contains the following information: - PersonFIFAId - Id of a person that is a subject to the change - Actor Name - Who performed the merge operation - Operation Timestamp - When the merge operation was performed

### 7.3.2 Handler interface

SDK exposes `IPersonNameChangedNotificationHandler` interface which can be used to process a notification.

## 7.4 GenderChangedNotification

This notification is created when a change of a person gender is made using update. If you store any data for the person, after the change, you might want to update a record in your DB.

### 7.4.1 Contents

The message contains the following information: - PersonFIFAId - Id of a person that is a subject to the change - Before - Gender before the change - After - Gender after the change - Actor Name - Who performed the merge operation - Operation Timestamp - When the merge operation was performed

### 7.4.2 Handler interface

SDK exposes `IGenderChangedNotificationHandler` interface which can be used to process a notification, e.g. update the person data in an internal NRS' database.

## 7.5 DateOfBirthChangedNotification

This notification is created when a change of a person date of birth is made using update. If you store any data for the person, after the change, you might want to update a record in your DB.

### 7.5.1 Contents

The message contains the following information: - PersonFIFAId - Id of a person that is a subject to the change - Before - Date of birth before the change - After - Date of birth after the change - Actor Name - Who performed the merge operation - Operation Timestamp - When the merge operation was performed

### 7.5.2 Handler interface

SDK exposes `IDateOfBirthChangedNotificationHandler` interface which can be used to process a notification, e.g. update the person data in an internal NRS' database.
