Imgur API (400 Error)

To whom it may concern, Am I missing something? Trying to do a simple post to Imgur via their API. My HTML

Second: I requested the Imgur API to do something before authorizing myself. They tell you to do this RIGHT in the [documentation][1], so there's really no excuse to sidestep this. Thus, all I needed to do to authorize is, first, do an $http.get('https://api.imgur.com/oauth2/authorize?client_id=<client_id>&response_type=<response_type>').then(function(data){ console.log(awesomeImgurData); });
