Permissions in JWT always empty

Help
1

Hi there,
i’m trying to secure my API with RBAC.

On Auth0 dashboard i’ve created an Web-App and an API, authorize the App to use this API,
added some permissions to the API and enabled RBAC Setting,
image
created a role with a permission of the API,
assigned this role to a user,
logged in to the App with this user.
As this App retrieved a token for this API from endpoint /oauth/token with params:

{
  "client_id":"<app-id>",
  "client_secret":"<app-secret>",
  "audience":"https://test.app/api/test",
  "grant_type":"client_credentials"
}

, the permissions claim of the returned JWT is empty. What is wrong or is any configuration missing?

The JWT is like this:

{
  "alg": "RS256",
  "typ": "JWT",
  "kid": "********"

  "iss": "https://***.auth0.com/",
  "sub": "**************@clients",
  "aud": "https://test.app/api/test",
  "iat": 1624679108,
  "exp": 1624679168,
  "azp": "**************",
  "gty": "client-credentials",
  "permissions": []
}

Hi @pinalto,

Welcome to the Community!

When you request a token with the client credentials grant, you are not requesting the token on behalf of a user. That grant is used for machine-to-machine (M2M) access.

To get the permissions associated with the user’s roles in the token, you will need to log in as the user. Try logging in as the user with one of our sample apps.
