Xsolla API uses basic access authentication. All requests to API must contain the Authorization: Basic <your_authorization_basic_key> header, where your_authorization_basic_key is the project_id:api_key pair encoded according to the Base64 standard.

Go to Xsolla Publisher Account to find values of the parameters:

• project_id on the All projects > Project ID page
• api_key on the Company settings > API key tab.

You can use merchant_id instead of project_id. It doesn't affect functionality. To find merchant_id, go to Company settings > Company > Merchant ID.

By default, the Xsolla Login User JWT (Bearer token) is used for authorization. You can try calling this endpoint with a test Xsolla Login User JWT token: Bearer eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJleHAiOjE5NjIyMzQwNDgsImlzcyI6Imh0dHBzOi8vbG9naW4ueHNvbGxhLmNvbSIsImlhdCI6MTU2MjE0NzY0OCwidXNlcm5hbWUiOiJ4c29sbGEiLCJ4c29sbGFfbG9naW5fYWNjZXNzX2tleSI6IjA2SWF2ZHpDeEVHbm5aMTlpLUc5TmMxVWFfTWFZOXhTR3ZEVEY4OFE3RnMiLCJzdWIiOiJkMzQyZGFkMi05ZDU5LTExZTktYTM4NC00MjAxMGFhODAwM2YiLCJlbWFpbCI6InN1cHBvcnRAeHNvbGxhLmNvbSIsInR5cGUiOiJ4c29sbGFfbG9naW4iLCJ4c29sbGFfbG9naW5fcHJvamVjdF9pZCI6ImU2ZGZhYWM2LTc4YTgtMTFlOS05MjQ0LTQyMDEwYWE4MDAwNCIsInB1Ymxpc2hlcl9pZCI6MTU5MjR9.GCrW42OguZbLZTaoixCZgAeNLGH2xCeJHxl8u8Xn2aI.

You can use the Pay Station access token as an alternative.

When selling a cart with games or physical goods, you can call the endpoint without authorization. To do this:

• add a unique identifier to the x-unauthorized-id parameter in the header for games and physical goods
• add user’s email to the x-user parameter (Base64 encoded) in the header for games.
