title: Can I use Google's email-settings sendas API with oauth2
body: <p>I have a valid oauth2 access_token, that has been authorized with the '<a href="https://apps-apis.google.com/a/feeds/emailsettings/2.0/" rel="nofollow">https://apps-apis.google.com/a/feeds/emailsettings/2.0/</a>' scope.  I can successfully use this access_token to make requests against other profile api endpoints.</p>
  
  <p>I'm trying to fetch the list of email addresses the account has been verified to send as.  I'm using <a href="https://apps-apis.google.com/a/feeds/emailsettings/2.0/" rel="nofollow">https://apps-apis.google.com/a/feeds/emailsettings/2.0/</a>{domain}/{user}/sendas as the url, and passing the access token in the access_token param.   I'm getting an authorization error when attempting this.</p>
  
  <p>Is the emailsettings API supposed to be accessible via oauth2?  What am I doing wrong?</p>
