Actually, I am also working on google API. I try to retrieve documents from my google docs. I found the Zend framework for G_data. It contain the API to access google docs. However, i am stucking with using the error message: `invalid token`. It makes me suspect that the API can only be used for Google Apps Premium edition. There are ways that you don't need o use the API. You just hard-core coding, this link show that: http://code.google.com/apis/spreadsheets/data/3.0/developers_guide_protocol.html#ListingSpreadsheets . However, I hvnt tried it yet coz I am not very good at sending POST and GET HTTP Request. If you know any way to work about it, please enlighten me.
