Lock for Android v2 Delegation API


After a successful authentication, you can request credentials to access third party apps like Firebase or AWS that are configured in your Auth0 App's Add-On section. In order to do that you need to make a request to our Delegation API using a valid JWT.

Here's an example

Auth0 auth0 = new Auth0("YOUR_CLIENT_ID", "YOUR_AUTH0_DOMAIN");
AuthenticationAPIClient client = new AuthenticationAPIClient(auth0);
String apiType = "firebase";
String token = //Your Auth0 ID Token of the logged in User
client.delegationWithIdToken(token, apiType)
  .start(new BaseCallback<Map<String, Object>, AuthenticationException>() {
        public void onSuccess(Map<String, Object> payload) {
            //Your Firebase token will be in payload

        public void onFailure(AuthenticationException error) {
            //Delegation call failed

The delegation response is a generic Map since the structure of it will depend of the api_type used for delegation

The only two parameters required are id_token and api_type, the former is the token returned by Auth0 after a successful authentication, the latter specifies the API credentials we want to retrieve, and these are its supported values:

  • app: Your Auth0 application. This will get a new JWT token.
  • aws: Amazon Web Services API.
  • azure_sb: Windows Azure Service Bus.
  • firebase: Firebase API.
  • salesforce_api: Salesforce API.
  • salesforce_sandbox_api: Salesforce Sandbox API.
  • sap_api: SAP OData.
  • wams: Windows Azure Mobile Services.
