AuthenticateHandoff

Authenticate the user with a custom Authentication Handoff.

Error Handling Example

public void FailureCallback(int statusCode, int reasonCode, string statusMessage, object cbObject) {
    switch (reasonCode) {
        case ReasonCodes.MISSING_IDENTITY_ERROR: { // Identity does not exist (and client has orphaned profileId)

            // Reset profileId and re-authenticate
            BrainCloudClient.Get().AuthenticationService.ResetStoredProfileId();
            BrainCloudClient.Get().AuthenticationService.AuthenticateEmail(email, password, true);
            break;
        }
        case ReasonCodes.SWITCHING_PROFILES: { // Identity belongs to a different profile

            // Reset profileId and re-authenticate
            BrainCloudClient.Get().AuthenticationService.ResetStoredProfileId();
            BrainCloudClient.Get().AuthenticationService.AuthenticateEmail(email, password, forceCreate);
            break;
        }
        case ReasonCodes.MISSING_PROFILE_ERROR: { // Identity does not exist

            // The account doesn't exist - create it now.
            BrainCloudClient.Get().AuthenticationService.AuthenticateEmail(email, password, true);
            break;
        }
        case ReasonCodes.TOKEN_DOES_NOT_MATCH_USER: { // User auth information is incorrect

            // Display a dialog telling the user that the password provided was invalid,
            // and invite them to re-enter the password.
            // ...
            break;
        }
        default: { // Uncaught reasonCode

            // Log the error for debugging later
            // ...
            break;
        }
    }
}

Usage

http://localhost:3000

C#

SuccessCallback successCallback = (response, cbObject) =>
{
    Debug.Log(string.Format("Success | {0}", response));
};
FailureCallback failureCallback = (status, code, error, cbObject) =>
{
    Debug.Log(string.Format("Failed | {0}  {1}  {2}", status, code, error));
};

_bc.AuthenticationService.AuthenticateHandoff(
    handoffId, securityToken, successCallback, failureCallback);

C++

const char* handoffId = "handoffId";
const char* securityToken = "securityToken";

_bc->getAuthenticationService()->authenticateHandoff(
    handoffId,
    securityToken,
    this);

Objective-C

NSString* handoffId = @"handoffId";
NSString* securityToken = @"securityToken";
BCCompletionBlock successBlock;      // define callback
BCErrorCompletionBlock failureBlock; // define callback

[[_bc authenticationService]
        authenticateHandoff:handoffId
              securityToken:securityToken
            completionBlock:successBlock
       errorCompletionBlock:failureBlock
                   cbObject:nil];

Java

String handoffId = "handoffId";
String securityToken = "securityToken";
this; // implements IServerCallback

_bc.getAuthenticationService().authenticateHandoff(handoffId, securityToken, this);

public void serverCallback(ServiceName serviceName, ServiceOperation serviceOperation, JSONObject jsonData)
{
    System.out.print(String.format("Success | %s", jsonData.toString()));
}
public void serverError(ServiceName serviceName, ServiceOperation serviceOperation, int statusCode, int reasonCode, String jsonError)
{
    System.out.print(String.format("Failed | %d %d %s", statusCode,  reasonCode, jsonError.toString()));
}

JavaScript

var handoffId = "handoffId";
var securityToken = "securityToken";

_bc.authentication.authenticateHandoff(handoffId, securityToken, result =>
{
    var status = result.status;
    console.log(status + " : " + JSON.stringify(result, null, 2));
});

Dart

var  handoffId = "handoffId";
var  securityToken = "securityToken";

ServerResponse result = await _bc.authenticationService.authenticateHandoff(handoffId:handoffId, securityToken:securityToken);

if (result.statusCode == 200) {
    print("Success");
} else {
    print("Failed ${result.error['status_message'] ?? result.error}");

Common Error Code

Status Codes

Code	Name	Description
40206	MISSING_IDENTITY_ERROR	The identity does not exist on the server and forceCreate was false [and a profileId was provided - otherwise 40208 would have been returned]. Will also occur when forceCreate is true and a saved [but un-associated] profileId is provided. The error handler should reset the stored profile id (if there is one) and re-authenticate, setting forceCreate to true to create a new account. A common cause of this error is deleting the user's account via the Design Portal.
40207	SWITCHING_PROFILES	Indicates that the identity credentials are valid, and the saved profileId is valid, but the identity is not associated with the provided profileId. This may indicate that the user wants to switch accounts in the app. Most often an app will pop-up a dialog confirming that the user wants to switch accounts, and then reset the stored profileId and call authenticate again.
40208	MISSING_PROFILE_ERROR	Returned when the identity cannot be located, no profileId is provided, and forceCreate is false. The normal response is to call Authenticate again with forceCreate set to true.
40217	UNKNOWN_AUTH_ERROR	An unknown error has occurred during authentication.
40307	TOKEN_DOES_NOT_MATCH_USER	The user's password is incorrect.
