title: Authenticating for two endpoints apis
body: <p>I'm building a small app using javaScript.
  I have two endpoints apis I'm trying to use in the app - each one of them is used by other apps that don't need the other api (so I don't want to combine them into one big api).</p>
  
  <p>I can't find a way to Oauth2 authenticate for both of them using two different client_ids.
  Is it possible? If so, how?</p>
  
  <p>It seems like gapi.auth supports only one token etc.</p>
  
  <p>Thanks.</p>
