title: Google contacts import using oauth2.0
body: <p>What possible ways to import google contacts using python and <strong>oauth2.0</strong> exists?</p>
  
  <p>We successfully got credentials, and our application requests access to contacts, but after getting credentials I can't find way to discover contacts api. </p>
  
  <p>So things like:</p>
  
  <pre><code> from apiclient.discover import build
   import httplib2
   http = httplib2.Http()
   #Authorization
   service = build("contacts", "v3", http=http) 
  </code></pre>
  
  <p>Gives us <code>UnknownApiNameOrVersion</code> exception. 
  It looks like Contacts API not in list of supported APIs for apiclient. </p>
  
  <p>I'm looking for alternative ways. </p>
