  <p>From the link above I add the email scope</p>
  
  <pre><code>https://www.googleapis.com/auth/plus.me
  https://www.googleapis.com/auth/userinfo.email
  </code></pre>
  
  <p>But I dont understand the following</p>
  
  <p><em>Once you have a valid OAuth token, you can use it to make API calls to the Email Display API endpoint:
  <a href="https://www.googleapis.com/userinfo/email" rel="noreferrer">https://www.googleapis.com/userinfo/email</a>
  If the token is not valid, a 401 error will be returned.  If the token is valid, then the user's Email address will be returned.  The API will also return a boolean value to indicate whether Google has verified that the user owns that Email address.  However most installed applications will ignore that value.</em></p>
