Yes the URL is valid. The: {“error”:{“message”:“SOMETHING WRONG WRONG 404 - Not found.”}}
you see is just something I put there for default if you are trying to make a request that I did not set up. Entering the URL in the browser is making a GET request that I did not set anything for so it defaults to my generic response of 404 not found text. If you make a POST request to that URL though something different will happen. It would run the function I posted previously.
