I am terribly confused on how one is to write a javascript client (non-gadget) to a private Google Spreadsheet using supported APIs? I have no difficulties getting an OAuth2 Drive API client going, but then there is no spreadsheet support!
https://developers.google.com/apis-explorer
This issue crudely asks for the spreadsheet API to appear on that page:
http://code.google.com/p/google-api-javascript-client/issues/detail?id=37
I am probably missing something obvious, so thank you for your kindness to help me...
Update:
Wow, this is kicking my behind! So, I am going down the path of attempting to take the access_token from the Oauth2 workflow and then set the gdata API Authorization header like so:
service = new google.gdata.client.GoogleService('testapp');
service.setHeaders({'Authorization': 'Bearer '+ access_token});
Unfortunately, chrome console shows that this header is not actually getting sent to google when I do something like
service.getFeed(url, cb, eb);
Uffff!
