Returns a credential

Credentials are a pair of a unique identifier and a matching
shared secret.  OAuth defines three classes of credentials:
client, temporary, and token, used to identify and authenticate
the client making the request, the authorization request, and
the access grant, respectively.
  -- RFC 5849

You will need to turn your app token and app secret into a credential.

If you store token credentials persistently then you can recombine the identifier and secret with this procedure.
