UnityWebRequest Responds with 405

The response of 405 would lead me to believe that my method I’m calling in my web api isn’t set to accept post.

However, I can type the same url in fiddler and it works, but with Unity I get 405.

What am I doing wrong?

I’m using latest Unity 2017.

@nonlin: How do you know you are getting 405? Do you Debug.Log the response from UnityWebRequest?
I just realised this question is more than a year old… XD
