Access Tokens

Access token in the Amazon Pay API authenticate merchants requesting user information. This token, specific to clients and users, enable Amazon Pay to identify which user's details to share with the requesting merchant. They are essential for securely accessing customer consented data, ensuring precise data transmission, and maintaining privacy protection.

Obtain Access Tokens

You can obtain an access token by calling the Access Token API.

There are two ways to call the API:

  • If you are a new merchant, use the Auth grant from the client-side SDK.

  • If you are an existing merchant, use the refresh token if you already have the refresh token.

The Access Token API returns a token pair called access_token and refresh_token. The access token must be used in all the other APIs as a user identifier.
