  description: "Registered users get an authentication GUID by email after they accept the web services agreement. The docs say: 'We will process your application and e-mail you an authentication GUID (Globally Unique Identifier) which is required to access the ABN Lookup web services.' The GUID is sent as a request element (authenticationGuid / authenticationGUID) on every SOAP or HTTP GET/POST method, and as the guid parameter on the JSONP services."

  errors:
  - The GUID entered is not recognised as a Registered Party
  - The party identified by this GUID has not been registered for the requested service
note: There is no OAuth, so no scopes artifact. The credential is a long-lived shared GUID, not a signed token.
