I have been using DocuSign SOAP Based API calls to create and send envelopes and am using legacy authentication method in which I can specify email address and password of the DocuSign user who is going to create envelopes.
One our client have multiple DocuSign account with the same user. When I setup an authentication header thru the SOAP based API call, I do not have a way to specify which account I am making API calls against.
How do I make sure that I am making API calls against the specific account?
