Hi again!
I'm now getting the following response on Postman:
The server cannot service the request because the media type is unsupported.
My request is exactly how you described above, and I'm sending it as application/xml, in a POST request. I noticed, however, that my password contains special characters (#, %, !, $); do you think this is causing the problem?
