Is it possible to use Google Apps Marketplace with Oauth2 and OpenID

Question

I have website which uses Oauth2 for communication with Google APIs. And it works fine. Now i need to make it "Google Marketplace compliant" to be listed there. Googles docs says about Oauth or Federated Login, but it doesn't precised if Oauth2 works too.

Does anyone has experience in such integration? May i keep Oauth2 and add OpenID to work with Marketplace, or i have to rework it for Federated Login?

Thanks!

Answer 1

When you list your app in the marketplace, you will get a consumer key and secret which you can use for 2-Legged OAUTH for every google apps domain that installed your app. So the answer is YES.

Answer 2

The answer is NO as of July 9, 2012. Google is in the process of adding OAuth2 for Apps Marketplace https://developers.google.com/identity-toolkit/v1/marketplace#oauth2
