This section describes API calls for working with Login. Set up your Login project in Publisher Account before sending requests.

You have access to the following Login project types in Publisher Account:

• Standard Login project
• Shadow Login project To find more information on it, see Cross-platform account feature.

Is a Login project that is used to store main accounts.

Is a Login project that is used to store platform accounts.

Is an account type that is created in a standard Login project and linked to platform accounts. The main account is used to identify the player on different platforms.

Is an account type that is created in a shadow Login project and connected to a definite publishing platform. The platform account can’t be linked to another platform account. Also, you can’t unlink the accounts from a main account.

Is a game platform that is used for game distribution (e.g. Steam, PlayStation, Xbox, etc.).

Login API supports the following token types:

• User token. It is used for sending requests to the following user resources:
  • profile
  • friends
  • attributes
• Server token. It is used for sending requests to application resources such as settings or user data. The following requests are available:
  • Create platform accounts
  • Get user data
  • Link accounts
  • Link user accounts via external ID

To get the token, send one of the following requests:

• user registration (JWT or OAuth 2.0)
• authentication by username and password (JWT, OAuth 2.0, or JWT auth by username and password)
• authentication via social networks (JWT or OAuth 2.0)
• silent authentication (JWT or OAuth 2.0)
• authentication via a social network access token
• authentication via a publishing platform

After JWT authentication, the user is redirected to the Callback URL with a token in a query-parameter: <Callback URL>?token=<User token (JWT)>.

After OAuth 2.0 protocol-based authentication, send the Generate JWT request to the Xsolla Login server to exchange the received code parameter for a user token (access_token).

Using a server token requires an OAuth 2.0 client for server authentication. We don’t have settings for this type of OAuth 2.0 clients in Publisher Account. Сontact your Account Manager to create a client.

To get a token, send a Generate JWT request with the grant_type=client_credentials parameter.

Every token has a JWT format and contains a definite information in a payload.

User JWT is a token received as a result of authentication or registration. A token payload contains information about the user and authentication call.

Getting a user token via the OAuth 2.0 protocol requires an OAuth 2.0 client. The user token is passed in the Authorization: Bearer <JWT> header.

A token will contain the main claims after authentication or email address confirmation. Presence of these claims does not depend on the user database and authentication call.

After successful authentication, every user has a JWT generated for them. Generated JWT is signed by a secret key. To make sure that a JWT is relevant and belongs to the user of your Login project, you should validate its value.

To validate a JWT:

1. Open your project in Publisher Account.
2. Click Login in the side menu and go to Login projects > your Login project > General settings.
3. In the Authorization block, copy the Secret key value.
4. Choose the library and connect it on the server side of your application.
5. Pass the secret key value to the validation function entry.
