You say they work in the web browser. This leads me to believe that the endpoints are accepting GET requests rather than POST, since GET is what you do when you type in a URL into the address bar. And by the way, your commented code also looks like a GET with a querystring. Are you sure you should be posting to the endpoints? Try it with UnityWebRequest.Get just to be sure.
