Glossary

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.

Rate limits

Are the restrictions applied by Xsolla API on the frequency of access by a user within a defined timeframe.

Standard Login project

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

Shadow Login project

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

Main account

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.

Platform account

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.

Publishing platform

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

Authentication

Login API supports the following token types:

Authentication schemes

You can determine whether an API call is client or server-side by the scheme of authentication:

  • Client-side — are called without authentication or with the Authorization header: Bearer <user_JWT> header, where <user_JWT> — is the user token.
  • Server-side API calls for implementing the user flow — are called with the header: X-SERVER-AUTHORIZATION: <server_JWT>, where <server_JWT> — is the server token.

Getting a user token

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

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).

Getting a server token

To get a server token:

  1. Set up server OAuth 2.0 client.
  2. Generate server JWT.

Set up server OAuth 2.0 client

  1. Open your project in Publisher Account and go to the Login section.
  2. Click Configure in the panel of a Login project.
  3. Go to the Security block and select the OAuth 2.0 section.
  4. Click Add OAuth 2.0 Client.
  5. Check the Server (server-to-server connection) box.
  6. Specify Token lifetime.
  7. Click Connect.
  8. Copy and save the client ID and secret key.

Generate server JWT

On the back end of your application, implement a method to get the server JWT using the Generate JWT API call. The request must contain the following parameters:

  • grant_type is the type of getting JWT, pass the client_credentials value.
  • client_secret is the secret key that is received when you set up the server OAuth 2.0 client.
  • client_id is the client ID received when you set up the server OAuth 2.0 client.

Rate limits

To prevent Xsolla system overloads and protect against sudden spikes in incoming traffic, Xsolla limits the number of requests received by the Xsolla API within a specified period of time. If the limit is exceeded, the Xsolla API returns an HTTP response with the 429 status code.

Rate limits vary by method, IP-address, authentication scheme, and other factors.

Rate limits for server-side methods are applied to methods with server-side authentication — methods that are called with the X-SERVER-AUTHORIZATION: <server_JWT> header, where <server_JWT> is the server token.

Rate limits for client-side methods are applied to methods without authentication or with client-side authentication — methods that are called with the Authorization: Bearer <user_JWT> header, where <user_JWT> is the user token.

Example of a method with server-side authentication: Example of a method with server-side authentication Example of a method with client-side authentication: Example of a method with server-side authentication

Rate limits for client-side methods do not change and are necessary to prevent brute-force attacks. The maximum request rate for server-side methods is higher than for client-side methods. You can refer to the recommendations on how to manage rate limits in the documentation.

Note In certain cases, it is possible to adjust the rate limits by request. To request the rate limits adjustment, contact your Customer Success Manager or email csm@xsolla.com.

JWT structure

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

User JWT

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.

Main claims

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.

 
Claim Type Required Description
exp Unix Timestamp Yes Date and time of token expiration. Default expiration time is 24 hours. You can change expiration time for every Login project.
iss string Yes Service that signed the token: https://login.xsolla.com.
iat Unix Timestamp Yes Date and time of giving the token.
sub string (UUID) Yes User ID written on the Xsolla Login server side.
groups array Yes

The list of groups the user is in. Every group is written in the following format:

  • xsolla_login — login via username/email and password.
  • social — social login
  • email — passwordless login via one-time code received by email.
