I am trying to create an application with DocuSign Connect. In DocuSign Connect I have enabled Include Basic Authentication Header, but still I am not able to make a call on the URL provided. 

I checked the logs on the server and the request reached the server but was rejected because of invalid credentials.

I am able to make a call to the URL from postman with the same username and password. Am I missing some settings here? Is DocuSign not sending the authentication in the header as “Basic <Credentials>” or is it doing something else?

Thanks in advance.
