OAuth, OpenID and the Google Data APIs

With a properly generated authentication token, your web apps can
securely consume and create content in Google applications. This talk
will provide you with the concepts and tools you need to get started
with OAuth and the Google Data APIs. We’ll show you when and where to
use the APIs, code some example apps, and demonstrate how they all
integrate with Google APIs and other developer products.

We’ll also discuss how to setup you web app to let visitors sign in
using their Google user accounts. Federated Login, based on the OpenID
standard, frees users from having to set up separate login accounts
for different web sites, and frees web site developers from the task
of implementing login authentication measures. Lastly, we’ll show how
applications that adopt OpenID and integrate with the Google Data APIs
can be listed in the Google Apps Marketplace and made easily
discoverable by over 25 million users and 2 million business that use
Google Apps.
