It's possible to create authentication for my API clients using auth0?

Hi @marcelo.aimone,

Welcome to the Auth0 Community!

Yes, your use case is possible. :raised_hands:

  1. Call Your API Using the Client Credentials Flow.
  2. Use API-A(Management API) to create users.
  3. Use API-A(Management API) to create API-B with reduced scope.
  4. For users to use API-B and authenticate through API-A, this requires authentication through two separate audiences. First, authenticate the users using the authorization code flow against API-A. Once that’s complete, you can silently authenticate the user against API-B to get a new set of tokens for API-B.

Let me know if you have any questions.

Thanks,
Rueben
