title: Is "Authorized redirect URI" mandatory when setting up a new clientId under google developers console?
body: <p>The authorized redirect URI is used by google to do a callback to pass the authorization token.</p>
  
  <p>It is also used for validation by google. So when receiving the actual oauth request, google checks to see if the callback url given in the request is same as "Authorized redirect URI" and if not it throws error.</p>
  
  <p>My requirement is to prevent google from doing this validation as I want to be able to pass different callback urls at run time . I tried giving the "authorized redirect URI" as empty, but that doesn't work. Any suggestions ?</p>
