How to use the Google Analytics API with Zend OAuth?

I never post on forums, so I hope that I don't break your code. But I have a question about the capabilities of Zend OAuth.

I tried to use it to get feeds from the Google Analytics API, but I just can't get it to work.

I have an OAuth input that works fine, and I can use it with Google Docs, no problem. But Zend has not come with Google Analytics support yet.

Now I will post my code, and if anyone finds out how to get a feed from Google Analytics using the Zend OAuth functions, I would appreciate it - and there really is not enough information on the Internet on this topic

In addition, I write it as a Wordpress plugin, so ignore all get_option and update_option, etc. Imagine using Session instead :)

EDIT: Oh, and one more thing. Google Analytics uses this type of URL to retrieve feeds: https://www.google.com/analytics/feeds/data?ids=ga%3A0000000&metrics=ga%3Apageviews&start-date=2011-05-09&end-date=2011-05- 23 & max-results = 50

   $consumerKey = 'XXX';
   $secret = 'XXX';

   require_once 'Zend/Loader.php';
   Zend_Loader::loadClass( 'Zend_Gdata_HttpClient' );
   Zend_Loader::loadClass( 'Zend_Gdata_Docs' );
   Zend_Loader::loadClass( 'Zend_Gdata_Spreadsheets' );
   Zend_Loader::loadClass( 'Zend_Oauth_Consumer' );
   Zend_Loader::loadClass( 'Zend_Http_Client' );
   Zend_Loader::loadClass( 'Zend_Gdata_Gbase' );

   // set your Google consumer key / secret 
   $CONSUMER_KEY       = $consumerKey;
   $CONSUMER_SECRET    = $secret;
   $RETURN_TO = 'http://' . $_SERVER['HTTP_HOST'] . $_SERVER['SCRIPT_NAME'];

   // Multi-scoped token.
   // Sorry! I'm using the analytics scope at this particular place in the code. In the bottom of this code though, there some request code that needs the Google Docs scope. If you want a working example for Google Docs, change this scope accordingly.
   $SCOPES = array(
      'https://www.google.com/analytics/feeds/',
   );

   $oauthOptions = array(
      'requestScheme'       => Zend_Oauth::REQUEST_SCHEME_HEADER,
      'version'             => '1.0',
      'consumerKey'          => $CONSUMER_KEY,
      'consumerSecret'       => $CONSUMER_SECRET,
      'signatureMethod'       => 'HMAC-SHA1',
      'callbackUrl'          => $RETURN_TO,
      'requestTokenUrl'       => 'https://www.google.com/accounts/OAuthGetRequestToken',
      'userAuthorizationUrl'    => 'https://www.google.com/accounts/OAuthAuthorizeToken',
      'accessTokenUrl'       => 'https://www.google.com/accounts/OAuthGetAccessToken'
   );

   if ( trim( $accessToken ) == '' ) {
      $consumer = new Zend_Oauth_Consumer( $oauthOptions );

      echo 'yes 1';
      update_option( 'ni_trends_google_request_token', serialize( $consumer->getRequestToken( array( 'scope' => implode( ' ', $SCOPES ) ) ) ) );
      $approvalUrl = $consumer->getRedirectUrl( array( 'hd' => 'default' ) );
      echo '<a href="' . $approvalUrl . '">Grant access</a>';

      if ( trim( $accessToken ) == '' ) {
         update_option( 'ni_trends_google_access_token', serialize( $consumer->getAccessToken( $_GET, unserialize( $requestToken ) ) ) );
      }

      update_option( 'ni_trends_google_request_token', '' );
   }

   $accessToken = unserialize( $accessToken );

   // This is where I run into trouble. This is for Google Docs, and it working (although I have the Analytics Scope configured at the moment) - but how do I make my request and fetch the feed from Google Analytics?
   $httpClient = $accessToken->getHttpClient($oauthOptions);
   $client = new Zend_Gdata_Docs($httpClient, "yourCompany-YourAppName-v1");
   $feed = $client->getDocumentListFeed();
   echo "<pre>";
   echo "<ul>\n";
   foreach ($feed->entries as $entry) {
      echo "<li>$entry->title </li>\n";
   }
   echo "</ul>\n";
   echo "</pre>\n";

EDIT: Solved it as follows:

$accessToken = unserialize( $accessToken );

    $client = $accessToken->getHttpClient( $oauthOptions );
    $client->resetParameters();

    $parameters = array(
        'ids' => 'ga:26870853',
        'metrics' => 'ga:pageviews',
        'start-date' => '2010-01-08',
        'end-date' => '2011-05-22',
        'max-results' => '50'
    );

    $client->setUri('https://www.google.com/analytics/feeds/data');

    $client->setParameterGet($parameters);

    $client->setMethod(Zend_Http_Client::GET);

    $response = $client->request();

    print_r( $response );

    exit();
