title: Scope validation is failing for pub/sub and calendars
body: <p>I have developed an enterprise application which uses gmail sync for users. Have also implemented webhooks via pub/sub. Currently, we are into production. But our pub/sub scopes are not approved by google.</p>
  
  <p>Scopes that used for pub/sub:</p>
  
  <ol>
  <li><a href="https://www.googleapis.com/auth/pubsub" rel="nofollow noreferrer">https://www.googleapis.com/auth/pubsub</a></li>
  </ol>
  
  <p>Have few other scopes issue as well:</p>
  
  <ol>
  <li><a href="https://www.googleapis.com/auth/calendar.events" rel="nofollow noreferrer">https://www.googleapis.com/auth/calendar.events</a></li>
  <li><a href="https://www.googleapis.com/auth/gmail.readonly" rel="nofollow noreferrer">https://www.googleapis.com/auth/gmail.readonly</a></li>
  </ol>
