title: In GCM: Does API Project account have to be the same as Google Play Store account?
body: <p>I have a backend for sending GCM push notifications that uses an API-project (sender_id) created under my google-account. It works great with an app published under my Google Play Store account (same google-account as API-project).</p>
  
  <p>Now I have to publish an app for a friend under his Google Play Store account, and I would like to use the same sender_id I use in my own app (that way I do not need changes on my backend).</p>
  
  <ul>
  <li>Is this possible? Can his app under his Google Play Store account use a sender_id (API-project) created with a different google-account than Google Play Store google-account?</li>
  <li>If the answer is positive: is there any possibility that Google requires in the future that API-project and Google Play Store have to be in the same google-account? (for security reasons, for example)</li>
  </ul>
  
  <p>Thanks!</p>
