# App-only token
Use this approach if you want an access token to have app-only context. In this case, EmbedFAST will use an app-only token for authentication and retrieve user identification from the ‘embedfast-user-id’ header parameter to use for authorization (access control and validation).
{% hint style="info" %}
**Note:**
* The EmbedFAST Admin API **does not** support this approach.
* The EmbedFAST User (Client) API can use this approach if you need to integrate with any available authentication providers.
