Add a parameter called InvocationStatus in the Authenticate method. This parameter receives an object of type ExternalServiceInvocationStatus, which we previously defined.
Define_Map For(*INPUT) Class(#ExternalServiceInvocationStatus) Name(#InvocationStatus) Pass(*BY_REFERENCE) Mandatory(*NULL)
And add the following code to read the status from the response object after #Request.DoGet:
* Get the request status
If (#InvocationStatus *IsNot *Null)
#InvocationStatus.FromHttpResponse( #Request.Response )
Endif
