I'm doing a POST request to `https://api.stackexchange.com/2.2/users/<id>/inbox` to get the users' inbox items.  
However I'm getting a 400 error on the request, and a JSON body saying it was a 404 error `"this method cannot be called this way"` and `"error_name: no method"`.

I've form encoded the parameters, and set the content-type to `form-urlencoded`.

Here's the request in fiddler:
