Identify users

Introduction

If you have configured your application, you can start using GetSocial without any additional steps. GetSocial creates anonymous user by default, so you can access all the features right after SDK gets initialized.

Anonymous user is just a user, that has no identities added. User is created per device and stays there for next sessions. Anonymous users have default names like “User 12345678”, but you can easily change it.

Not supported by Web SDK

The Web SDK doesn’t have support for anonymous users. For security reasons, only trusted identities are allowed.

To check if user is anonymous:

Android

val isAnonymous = GetSocial.getCurrentUser()?.isAnonymous

iOS

let anonymous = GetSocial.currentUser().isAnonymous()

Unity

var anonymous = GetSocial.GetCurrentUser().IsAnonymous;

Flutter

var currentUser = await GetSocial.currentUser;
var isAnonymous = currentUser.isAnonymous;

React Native

const currentUser = await GetSocial.getCurrentUser();
const isAnonymous = currentUser.isAnonymous;

Identify user

If you have internal login system or use any social authentication, you should connect your account to GetSocial user, so you can retrieve the same GetSocial user from another devices or recover it once app was reinstalled or user was logged out.

To connect GetSocial user with yours, you should add your identity to GetSocial user.

Identities

An identity is some unique user data to identify them among other users. You can use any auth provider to create an identity (your custom login, facebook, twitter, google, github, etc). Each user may have any number of different identities, but only one of the same provider. It means that you may attach one facebook, one twitter and one custom identity, but you can not attach two facebook identities. Read more how to attach multiple identities.

To create an identity:

Android

// Create Facebook identity
val fbIdentity = Identity.facebook(fbAccessToken)

// Create Custom Identity
val custom = Identity.custom(providerId, userId, accessToken)

iOS

// Create Facebook identity
let fbIdentity = Identity.facebook(accessToken: fbAccessToken)

// Create Custom Identity
let custom = Identity.custom(providerId: providerId, userId: userId, accessToken: accessToken)

Unity

// Create Facebook identity
var fbIdentity = Identity.Facebook(fbAccessToken);

// Create Custom Identity
var customIdentity = Identity.Custom(providerId, userId, accessToken);

Flutter

// Create Facebook identity
var fbIdentity = Identity.facebook(fbAccessToken);

// Create Custom Identity
var customIdentity = Identity.custom(providerId, userId, accessToken);

React Native

// Create Facebook identity
const fbIdentity = Identity.createFacebookIdentity(accessToken);

// Create Custom Identity
const customIdentity = Identity.createCustomIdentity(providerId, userId, accessToken);

Web

// Create Facebook identity
const fbIdentity = GetSocialSDK.Identity.createFacebookIdentity(accessToken);

// Create Custom Identity
const customIdentity = GetSocialSDK.Identity.createCustomIdentity(providerId, userId, accessToken);

• providerId is a unique string defined by you for each provider (twitter, my_auth_system, gamecenter, etc).
• userId is a unique UserId for each user in the provided authentication system. So pair providerId-userId is unique for each user and helps GetSocial identify a user if them try to login from another device.
• accessToken is a string for security check, that could be some internal hash function in your app based on userId. If user is trying to authenticate again with the same providerId and userId, but different accessToken - GetSocial won’t allow to authenticate. accessToken can not be changed.

Add Identity

You have to add an identity to GetSocial user in the success callback of your authentication system.

Android

fun onLoginSuccess() {
    val userId = getCurrentUserId() // get user ID on your login provider
    val accessToken = calculateAccessTokenForUser(userId) // see the example of such a function below

    val identity = Identity.custom("my_auth_system", userId, accessToken)
    val currentUser = GetSocial.getCurrentUser()

    if (currentUser == null) {
        // you can't add identity before SDK is initialized
        return
    }

    currentUser.addIdentity(identity, {
        Log.d("CurrentUser", "Identity added successfully")
    }, { conflictUser: ConflictUser ->
        handleConflic(identity, conflictUser)
    }, { error: GetSocialError ->
        Log.d("CurrentUser", "Failed to add identity: $error")
    })
}

fun calculateAccessTokenForUser(userId: String): String {
    return ... // you should implement your function to be identical on all platforms
}

iOS

let userId = getCurrentUserId() // get user ID on your login provider
let accessToken = calculateAccessToken(userId) // see the example of such a function below
let identity = Identity.custom(providerId: "my_auth_system", userId: userId, accessToken: accessToken)
GetSocial.currentUser()?.addIdentity(identity, success: {
    print("Successfully logged into \(userId)")
}, conflict: { conflictUser in
    self.handleConflict(identity: identity, conflictUser: conflictUser)
}, failure: { error in
    print("Failed to log into \(userId)")
})

func calculateAccessToken(userId: String) -> String {
    return ... // you should implement your function to be identical on all platforms
}

Unity

var userId = GetCurrentUserId(); // get user ID on your login provider
var accessToken = CalculateAccessToken(userId); // generate access token. make sure token generation code returns the same result on every platform.
var identity = Identity.Custom("my_auth_system", userId, accessToken);
GetSocial.GetCurrentUser().AddIdentity(identity, () => {
    Debug.Log("Successfully logged into " + userId);
}, (conflictUser) => {
    HandleConflict(conflictUser);
}, (error) => {
    Debug.Log("Failed to log into " + userId);
});

string CalculateAccessToken(string userId)
{
    return ... // make sure token generation code returns the same result on every platform
}

Flutter

var userId = getCurrentUserId();  // get user ID on your login provider
var accessToken = calculateAccessToken(); // generate access token. make sure token generation code returns the same result on every platform.
var identity = Identity.custom('my_auth_system', userId, accessToken);
var user = await GetSocial.currentUser;
user.addIdentity(
    identity,
    () => { print('Successfully logged into ' + userId)},
    (conflictUser) => { handleConflict(conflictUser) },
    (error) => { print('Failed to log into ' + userId)});
}

String calculateAccessToken(String userId) {
    return ... // make sure token generation code returns the same result on every platform
}

React Native

const userId = getCurrentUserId();  // get user ID on your login provider
const accessToken = calculateAccessToken(); // generate access token. make sure token generation code returns the same result on every platform.
const identity = Identity.createCustomIdentity('my_auth_system', userId, accessToken);
const currentUser = await GetSocial.getCurrentUser();
currentUser.addIdentity(
    identity,
    () => { console.log('Successfully logged into ' + userId); },
    (conflictUser) => { handleConflict(conflictUser); },
    (error) => { console.log('Failed to log into ' + userId); });

func calculateAccessToken(String userId) {
    return ... // make sure token generation code returns the same result on every platform
}

Web

const userId = getCurrentUserId();  // get user ID on your login provider
const accessToken = calculateAccessToken(); // generate access token. make sure token generation code returns the same result on every platform.
const identity = GetSocialSDK.Identity.createCustomIdentity('my_auth_system', userId, accessToken);
const currentUser = GetSocialSDK.GetSocial.getCurrentUser();
currentUser.addIdentity(identity)
    .then(() => {
        console.log('Successfully logged as ' + userId);
    }, (error) => {
        if (typeof error === GetSocialSDK.ConflictUser) {
            handleConflict(conflictUser);
        } else {
            console.log('Failed to log into ' + userId);
        }
    });

Trusted Identities

A trusted identity is a an identity that GetSocial can verify and validate internally. We currently support 2 types of Trusted Identities: Custom (verified using a signed JSON Web Token) and Facebook (verified against their servers).

In the GetSocial Dashboard, you can also configure to only allow trusted identities. In this case, any identity that is not trusted will be rejected.

Add a Custom Trusted Identity

A Custom Trusted Identity is an identity that is added using a signed JSON Web Token. If you have your own backend, then this is the preferred way to add a custom identity, as it allows GetSocial to verify and trust the ID you are setting.

To add a trusted identity, you should generate, in your backend, a signed JWT using your App’s shared secret available in the GetSocial Dashboard.

The JWT header should be:

{
  "alg": "HS256",
  "typ": "JWT"
}

and the payload should include:

{
  "sub": "your-user-id",
  "iat": 15162390,
  "exp": 1632471472
}

The final JWT signed with your-shared-secret will look like this:

eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJzdWIiOiJ5b3VyLXVzZXItaWQiLCJpYXQiOjE1MTYyMzkwLCJleHAiOjE2MzI0NzE0NzJ9.rXJSgFXYSqf3zHsLQ_oZB5SYKE_PkXgnjMlAJpbnKbY

Don’t expose your shared secret in your app

The signed JWT should be generated in your backend and then shared to your app to prevent exposing the shared secret to the public.

Trusted identities on SDK v7.6.0 and earlier

Full support for trusted identities was added on SDK v7.6.1, however you can still add a Trusted Identity in older versions by creating a custom identity with your UserId and the JWT as token.

Android

fun onLoginSuccess() {
    val userId = getCurrentUserId() // get user ID on your login provider
    val accessToken = getJWTFromYourBackend()

    val identity = Identity.trusted("my_auth_system", accessToken)
    val currentUser = GetSocial.getCurrentUser()

    if (currentUser == null) {
        // you can't add identity before SDK is initialized
        return
    }

    currentUser.addIdentity(identity, {
        Log.d("CurrentUser", "Identity added successfully")
    }, { conflictUser: ConflictUser ->
        handleConflic(identity, conflictUser)
    }, { error: GetSocialError ->
        Log.d("CurrentUser", "Failed to add identity: $error")
    })
}

iOS

let userId = getCurrentUserId() // get user ID on your login provider
let accessToken = getJWTFromYourBackend()
let identity = Identity.trusted(providerId: "my_auth_system", accessToken: accessToken)
GetSocial.currentUser()?.addIdentity(identity, success: {
    print("Successfully logged into \(userId)")
}, conflict: { conflictUser in
    self.handleConflict(identity: identity, conflictUser: conflictUser)
}, failure: { error in
    print("Failed to log into \(userId)")
})

Unity

var userId = GetCurrentUserId(); // get user ID on your login provider
var accessToken = GetJWTFromYourBackend();
var identity = Identity.Trusted("my_auth_system", accessToken);
GetSocial.GetCurrentUser().AddIdentity(identity, () => {
    Debug.Log("Successfully logged into " + userId);
}, (conflictUser) => {
    HandleConflict(conflictUser);
}, (error) => {
    Debug.Log("Failed to log into " + userId);
});

Flutter

var userId = getCurrentUserId();  // get user ID on your login provider
var accessToken = getJWTFromYourBackend();
var identity = Identity.trusted('my_auth_system', accessToken);
var user = await GetSocial.currentUser;
user.addIdentity(
    identity,
    () => { print('Successfully logged into ' + userId)},
    (conflictUser) => { handleConflict(conflictUser) },
    (error) => { print('Failed to log into ' + userId)});
}

React Native

const userId = getCurrentUserId();  // get user ID on your login provider
const accessToken = getJWTFromYourBackend();
const identity = Identity.createTrustedIdentity('my_auth_system', accessToken);
const currentUser = await GetSocial.getCurrentUser();
currentUser.addIdentity(
    identity,
    () => { console.log('Successfully logged into ' + userId); },
    (conflictUser) => { handleConflict(conflictUser); },
    (error) => { console.log('Failed to log into ' + userId); }
);

Web

const userId = getCurrentUserId();  // get user ID on your login provider
const accessToken = getJWTFromYourBackend();
const identity = GetSocialSDK.Identity.createTrustedIdentity('my_auth_system', accessToken);
const currentUser = GetSocial.getCurrentUser();
currentUser.addIdentity(identity)
    .then(() => {
        console.log('Successfully logged as ' + userId);
    }, (error) => {
        if (typeof error === GetSocialSDK.ConflictUser) {
            handleConflict(error);
        } else {
            console.log('Failed to log into ' + userId);
        }
    });
);

Add Facebook Identity

To add a Facebook Identity, you should provide the token you got from Facebook SDK after user’s authentication.

This could be either a User Access Token or an Authentication Token if you are using Facebook Limited Login.

1. Integrate Facebook SDK into your app as described in the Official Guide for iOS, Android or Unity.

2. Add Facebook identity to GetSocial user. Sample code is below:

   Android

   val accessTokenTracker = object: AccessTokenTracker() {
       override fun onCurrentAccessTokenChanged(oldAccessToken: AccessToken, currentAccessToken: AccessToken) {
           stopTracking() // stop tracking facebook access token changes as we don't need it anymore
   
           val currentUser = GetSocial.getCurrentUser()
   
           if (currentUser == null) {
               // you can't add identity before SDK is initialized
               // you can save the token to use it later
               accessToken = currentAccessToken
               return
           }
   
           currentUser.addIdentity(Identity.facebook(currentAccessToken), {}, {}, {})
       }
   }
   accessTokenTracker.startTracking()
   
   LoginManager.getInstance().logInWithReadPermissions(this@MainActivity, listOf("email", "user_friends")) // we need "user_friends" permission to import list of Facebook friends to GetSocial Social Graph
   

   iOS

   let login = FBSDKLoginManager()
   login.loginBehavior = FBSDKLoginBehaviorBrowser
   
   /* we need "user_friends" permission to import list of Facebook friends to GetSocial Social Graph */
   login.logIn(withReadPermissions: ["email", "user_friends"], fromViewController: self, handler: { result, loginError in
       if loginError == nil && result?.isCancelled == nil {
           let identity = Identity.facebook(accessToken: result?.token.tokenString)
   
           GetSocial.currentUser().addIdentity(identity, success: {
               print("Successfully logged into FB")
           }, conflict: { conflictUser in
               self.handleConflict(for: identity, conflictUser: conflictUser)
           }, failure: { error in
               print("Failed to log into FB")
           })
       }
   })
   

   Unity

   FB.Init(() => {
       var permissions = new List<string>(){"public_profile", "user_friends"}; // We need "user_friends" permission to import list of Facebook friends to GetSocial Social Graph
       FB.LogInWithReadPermissions(permissions, result => {
           if (FB.IsLoggedIn) {
               var aToken = Facebook.Unity.AccessToken.CurrentAccessToken;
               var identity = Identity.Facebook(aToken.TokenString);
               GetSocial.GetCurrentUser().AddIdentity (identity, OnSuccess, OnError, OnConflict);
           } else {
               Debug.Log("User cancelled login");
           }
       });
   });
   

   Flutter

   var fbIdentity = Identity.facebook(fbAcessToken);
   var user = await GetSocial.currentUser;
   user.addIdentity(
       fbIdentity,
       () => { print('Successfully logged into ' + fbIdentity)},
       (conflictUser) => { handleConflict(conflictUser) },
       (error) => { print('Failed to log into ' + fbIdentity)});
   }
   

   React Native

   // We need "user_friends" permission to import list of Facebook friends to GetSocial Social Graph
   LoginManager.logInWithReadPermissions(['email', 'user_friends', 'public_profile']).then((result) => {
       if (result.isCancelled) {
           console.log('FB Login cancelled');
       } else {
           AccessToken.getCurrentAccessToken().then((token) => {
               if (token != null) {
                   const fbIdentity = Identity.createFacebookIdentity(token.accessToken);
                   const currentUser = await GetSocial.getCurrentUser();
                   currentUser.addIdentity(fbIdentity, () => {}, (conflictUser) => {}, (error) => {});
               }
           });
       }
   }, (error) => {
       console.log('FB login failed with error: ' + error);
   });
   

   Web

   // We need "user_friends" permission to import list of Facebook friends to GetSocial Social Graph
   FB.login(function (response) {
       if (response.status === 'connected') {
           const fbIdentity = GetSocialSDK.Identity.createFacebookIdentity(response.authResponse.accessToken);
           const currentUser = GetSocialSDK.GetSocial.getCurrentUser();
           currentUser.addIdentity(fbIdentity);
       } else {
           console.log('FB login failed with status: ' + response.status);
       }
   }, {scope: 'public_profile,email,user_friends'});
   

For Facebook, we will retrieve the list of Facebook friends and import them to Social Graph, so you can get list of user’s friends through GetSocial.

GetSocial doesn’t automatically sync your Facebook profile info

Don’t forget to sync the display name and avatar of the GetSocial user with the values from Facebook. You can do it with a batch update to make it in one call.

Add Username Identity

If your app identifies users publicly using both, a display name (ie John D.) and a username or handle (johndoe), then we recommend using the username identity provider. This provider can be used as a standalone, as a trusted identity, and/or in combination with other identities.

The benefits of using the username identity is that usernames are unique, can be used to authenticate a user and are also searchable (none of the other identity providers are) when finding users.

To add a username identity, you can just follow the steps to Add Identity or Add a Custom Trusted Identity but set username as the identity provider providerId and the user’s username as userId.

We suggest not including any prefix like @ or # in the user’s username and only add it in your UI when needed.

Handle Conflicts

Besides success and failure callbacks, addIdentity has conflict. Conflict happens when identity you’re trying to add is already attached to one of GetSocial users. It may happen when:

• User has already logged in on another device.
• User reinstalled the application.
• User cleared application data.

Depending on the user intention and your application logic, you can choose one of the following strategies to resolve the conflict.

Strategy 1: stay with current user and don’t add identity:

Android

fun handleConflict(identity: Identity, conflictUser: ConflictUser) {
    // Do nothing in onConflict and user will stay the same.
    // Identity won't be added to any of the users.
}

iOS

func handleConflict(identity: Identity, conflictUser: ConflictUser) {
    // Do nothing in onConflict and user will stay the same.
    // Identity won't be added to any of the users.
}

Unity

void HandleConflict(Identity identity, ConflictUser conflictUser)
{
    // Do nothing in onConflict and user will stay the same.
    // Identity won't be added to any of the users.
}

Flutter

handleConflict(Identity identity, ConflictUser conflictUser) {
    // Do nothing in onConflict and user will stay the same.
    // Identity won't be added to any of the users.
}

React Native

handleConflict(authIdentity, conflictUser) {
    // Do nothing in onConflict and user will stay the same.
    // Identity won't be added to any of the users.
}

Web

handleConflict(conflictUser) {
    // Do nothing and user will stay the same.
    // Identity won't be added to any of the users.
}

Strategy 2: switch to conflict user:

Android

fun handleConflict(identity: Identity, conflictUser: ConflictUser) {
    // Call switchUser to replace current user with conflict one and add identity to conflict user.
    // After the successful switch, current user and his referral data will be lost.
    // To save the data: 1. copy data to intermediate variables; 2. save in to the conflict user properties after the successful switch.
    GetSocial.switchUser(identity, { /** onSuccess **/ }, { /** onError **/ })
}

iOS

func handleConflict(identity: Identity, conflictUser: ConflictUser) {
    // Call switchUser to replace current user with conflict one and add identity to conflict user.
    // After the successful switch, current user and his referral data will be lost.
    // To save the data: 1. copy data to intermediate variables; 2. save in to the conflict user properties after the successful switch.
    GetSocial.switchUser(to: identity, success: {
        print("Successfully switched user")
    }, failure: { error in
        print("Failed to switch user")
    })
}

Unity

void HandleConflict(Identity identity, ConflictUser conflictUser)
{
    // Call switchUser to replace current user with conflict one and add identity to conflict user.
    // After the successful switch, current user and his referral data will be lost.
    // To save the data: 1. copy data to intermediate variables; 2. save in to the conflict user properties after the successful switch.
    GetSocial.SwitchUser(identity, completionCallback);
}

Flutter

handleConflict(Identity identity, ConflictUser conflictUser) {
    // Call switchUser to replace current user with conflict one and add identity to conflict user.
    // After the successful switch, current user and his referral data will be lost.
    // To save the data: 1. copy data to intermediate variables; 2. save in to the conflict user properties after the successful switch.
    GetSocial.switchUser(identity).then(...);
}

React Native

handleConflict(identity, conflictUser) {
    // Call switchUser to replace current user with conflict one and add identity to conflict user.
    // After the successful switch, current user and his referral data will be lost.
    // To save the data: 1. copy data to intermediate variables; 2. save in to the conflict user properties after the successful switch.
    GetSocial.switchUser(identity);
}

Web

handleConflict(conflictUser) {
    // Logout
    GetSocialSDK.Auth.logout();
    // or notify about the error
    console.log('This identity belongs to user: ', conflictUser.displayName);
}

Logout

If your users can log out of your app, you should log out of GetSocial user too. Otherwise it will stay the same and will have connection with another user that will login after.

Android

fun onLogoutSuccess() {
    // New anonymous will be created. If your current user is anonymous - it will be lost.
    GetSocial.resetUser({ /** onSuccess **/, /** onError **/ })
}

iOS

func onLogoutSuccess() {
    // New anonymous user will be created. If your current user is anonymous - it will be lost.
    GetSocial.resetUser(success: successCallback, failure: failureCallback)
}

Unity

void OnLogoutSuccess()
{
    // New anonymous will be created. If your current user is anonymous - it will be lost.
    GetSocial.ResetUser(OnSuccess, OnError);
}

Flutter

onLogoutSuccess() {
    // New anonymous will be created. If your current user is anonymous - it will be lost.
    GetSocial.resetUser().then(...);
}

React Native

onLogoutSuccess() {
    // New anonymous will be created. If your current user is anonymous - it will be lost.
    GetSocialUser.reset();
}

Web

onLogoutSuccess() {
    // The session is removed and it's not possible to use the GetSocial services anymore
    // For security purposes, there are no anonymous users in web
}

Subscribe to GetSocial user changes to be notified about logout events too.

Handle Multiple User Identities

You may want to connect multiple identities (login with Facebook and Google at the same time). It will allow to log into that user with different auth providers.

Your user may have any number of different identities attached for different login providers, but only one identity for each provider.

You already know how to add identity. Once it is successfully added, you can log in using that identity.

To remove identity from user:

Android

val providerId = "my_auth_system"
val currentUser = GetSocial.getCurrentUser()
if (currentUser == null) {
    // you can't remove identity before SDK is initialized
    return
}

currentUser.removeIdentity(providerId, { /** onSuccess **/, /** onError **/ })

iOS

let providerId = "my_auth_system"
GetSocialUser.removeIdentity(providerId: providerId, success: success, failure: failure)

Unity

var providerId = "my_auth_system";
var currentUser = GetSocial.GetCurrentUser();
if (currentUser == null)
{
    // you can't remove identity before SDK is initialized
    return
}
currentUser.RemoveIdentity(providerId, OnSuccess, OnError);

Flutter

var providerId = "my_auth_system";
var currentUser = await GetSocial.currentUser;
if (currentUser == null) {
    // you can't remove identity before SDK is initialized
    return
}
currentUser.removeIdentity(providerId).then(...);

React Native

const providerId = 'my_auth_system';
const currentUser = await GetSocial.getCurrentUser();
currentUser.removeIdentity(providerId).then(() => {
    console.log('Successfully remove identity');
}, (error) => {
    console.log('Failed remove identity, error:' + error);
});

Web

const providerId = 'my_auth_system';
const currentUser = GetSocialSDK.GetSocial.getCurrentUser();
currentUser.removeIdentity(providerId)
    .then(() => {
        console.log('Successfully remove identity');
    }, (error) => {
        console.log('Failed remove identity, error:', error);
    });

To get all user identities:

Android

val identities = GetSocial.currentUser()?.getIdentities()

iOS

let identities = GetSocial.currentUser()?.identities

Unity

var identities = GetSocial.GetCurrentUser().Identities;

Flutter

var currentUser = await GetSocial.currentUser
var identities = currentUser.identities;

React Native

const currentUser = await GetSocial.getCurrentUser();
const identities = currentUser.identities;

Web

const currentUser = GetSocialSDK.GetSocial.getCurrentUser();
const identities = currentUser.identities;

where key is providerId and value is userId for that provider.

Change Logged In User

If you want to switch from one logged in user to another, do Logout first and then Login with a new user.

Warning

Don’t forget to do the logout, it is important to keep your user connected with proper GetSocial user, so you will receive correct analytics and referral data.

Subscribe to User Lifecycle Changes

User change handler is invoked when:

• SDK got initialized;
• You successfully switched user as in Strategy 2 of Handle Conflict section;
• You successfully reset user.

Not provided by Web SDK

This listener is not provided by the Web SDK. There is no switchUser method and a listener for the initialization can be set with addOnInitializedListener.

Set your custom event handler somewhere on the start of your application:

Android

class MainActivity : AppCompatActivity() {

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)

        // Setup GetSocial
        val listenerId = GetSocial.addOnCurrentUserChangedListener { newUser: CurrentUser ->
            Log.d("CurrentUser", "Is user anonymous? ${newUser.isAnonymous}")
            Log.d("CurrentUser", "What's user's avatar? ${newUser.avatarUrl}")
