I tried using google docs sample in the Zend Gdata demos and got the following error :
Fatal error: Uncaught exception 'Zend_Gdata_App_HttpException' with

I am using Zend library for the first time and am unable to figure out how Authorization works here. Please help

Answer 1

I'm not sure if this is fixed in the latest version of the Zend library but I went and updated this file in my Zend install:
library/Zend/Gdata/Docs.php
The constants around line 62 needed to be updated to change the http to https which now look like this in my install:
const DOCUMENTS_LIST_FEED_URI = 'https://docs.google.com/feeds/documents/private/full';
const DOCUMENTS_FOLDER_FEED_URI = 'https://docs.google.com/feeds/folders/private/full';
const DOCUMENTS_CATEGORY_SCHEMA = 'https://schemas.google.com/g/2005#kind';
const DOCUMENTS_CATEGORY_TERM = 'https://schemas.google.com/docs/2007#folder';
That did the trick.

You must use https instead of http if you want to connect to GoogleDocs, which is stated in the error message you are getting: Expected response code 200, got 403 403.4 SSL required. The parts of the message are interpreted like this:
Expected response code 200: the called method expect the http response code to be 200
got 403: the actual received http code
403.4 SSL required: a short description to the code
Look at List of HTTP status codes to get more information.
The examples from the Zend Framework: Documentation: Using Google Documents List Data API - Zend Framework Manual aren't up-to-date and should be like this:
$feed = $docs->getDocumentListFeed(
'https://docs.google.com/feeds/documents/private/full/-/document');
