OpenID and Google.GData.AccessControl.dll in C#

I am designing a web site to use OpenId and Google is one of the main providers I have selected. What I would like to do is use Google's Calendar & Contacts (possibly docs) as a backing store for each individual user. In other words, if the user on my site wants to have access to a Contacts List, Calendar, etc they must register their Google account. Then they can add/edit/delete to their heart's content as it is their info. (And yes, I have a specific idea in mind for where I am going, just need to figure out how to tie OpenID to GData.)

Has anyone written a tie in between OpenID/OAuth and using the Google APIs?

Solution

  • After a lot of digging in to this problem I have 2 ways of solving this.

    1. Use OpenID and on the user's profile, have them enter their google credentials (works but not a great solution)
    2. Use OAuth. This requires registering your domain with google and getting a key to use with OAuth. Once you set that up it is easy to access a end user's data stores on google.

    Look at google's OAuth 1.0 for Web Applications.

    Also look at OAuth-OpenID: You’re Barking Up the Wrong Tree if you Think They’re the Same Thing for a good overview of OpenID vs OAuth.
