I am using Nintex Workflow 2013 (18.104.22.168) with SharePoint 2013 on Windows Server 2008R2.
What I am trying to do is to use a Web Request action make a call to our products' (Ephesoft Enterprise) REST APIs.
If I run a test against an online test API site, with no credentials needed, this tests OK.
I then move on to the REST APIs from the Ephesoft product. I first do a test outside of Nintex to make sure I can connect and get the expected results. Once I have authenticated, I see the results I expect.
When I then go into Nintex Workflow, and run the same kind of test (same URL, same credentials I used outside of Nintex), I receive a 405 Method Not Allowed error.
My first thought is, how does Nintex send the credentials, as if I send in bad credentials, I expect the same result.
