title: Where is doc of available scopes of Google OAuth 2.0 API?
body: <p>I am looking for a list of all possible scope values for use with the Google OAuth 2.0 enabled API's, such as:</p>
  
  <pre><code>https://www.googleapis.com/auth/urlshortener
  https://www.googleapis.com/auth/tasks
  </code></pre>
  
  <p>I got lost in the Google API docs and can't find a page containing such information.  Where can I find it?</p>
  
  <p>Thanks.</p>
