title: Zend_Gdata and OAuth
body: <p>I successfully retrieved token key / secret after applying Google Hybrid Protocol (OpenID + OAuth).</p>
  
  <p>Then I'm looking into Zend documentation here:
  <a href="http://framework.zend.com/manual/en/zend.gdata.html" rel="nofollow">http://framework.zend.com/manual/en/zend.gdata.html</a></p>
  
  <p>... and into Calendar API example here:
  <a href="http://code.google.com/googleapps/marketplace/tutorial_php.html#Integrate-OAuth" rel="nofollow">http://code.google.com/googleapps/marketplace/tutorial_php.html#Integrate-OAuth</a></p>
  
  <p>They mention about AuthSub method supported by Zend_Gdata library
  (especially in Zend_Gdata_HttpClient class form what I can see).</p>
  
  <p>But I cannot figure out how to use my key/secret tokens retrieved by Hybrid method in order to access calendar feeds.</p>
  
  <p>Example mentioned above uses AuthSub authentication, while Google recommends to switch to OAuth if possible and where possible, instead of using AuthSub.</p>
  
  <p>Any ideas? Thanks.</p>
