title: Android Push - Third party server can't log in Google GCM to be whitelisted
body: <p>I am trying to test the new Android GCM API. </p>
  
  <p>In the client side, everything goes good. The application can register and unregister itself properly.</p>
  
  <p>In the third party server I have issues. I am testing it using the Python example server that Google provides but it can't authorize the connection with Google GCM because the project is not whitelisted. I have tried to whitelist it through <a href="https://services.google.com/fb/forms/gcm/" rel="nofollow">this website</a> but it always returns a 500 error.</p>
  
  <p>Also, I don't want to use upstream messaging at this moment but just send messages from the server to the devices. Do I still need to be whitelisted? In that case, is there any other Google resource to do that?</p>
