acquire-temporary-credential service #!optional callback-urlprocedure

This is the first step in the three step Redirection-Based Authorization defined in OAuth.

  1.  The client obtains a set of temporary credentials from the server
      (in the form of an identifier and shared-secret).  The temporary
      credentials are used to identify the access request throughout
      the authorization process.
        -- RFC 5849, Section 2

If you are speaking OAuth 1.0a or RFC 5849 then you must specify callback-url at this stage rather than at the authorize-resource-owner stage.
