Hi all, I’m new to Auth0 and to this forum so I apologize in advance if I ask any naive questions. Is there a way to modify the scopes returned in an access token? I tried using rules but rules seem to only apply to user logins. I want to add additional scopes based on the pesence of a scope requested. ---

Hi Joe. Rules don’t execute on a client-credentials exchange (machine-to-machine flows), but you can [use a hook](https://auth0.com/docs/api-auth/tutorials/client-credentials/customize-with-hooks) to accomplish the same purpose. ---
