External Authentication Appnet Web Api

I am using https://github.com/EddyVerbruggen/cordova-plugin-googleplus for external authentication in a mobile app. In response from google I get the following:

obj.email          // 'email@gmail.com'
obj.userId         // user id
obj.displayName    // 'My Name'
obj.idToken        // idToken that can be exchanged to verify user identity.
obj.serverAuthCode // Auth code that can be exchanged for an access token and refresh token for offline access

      

        
        
        
      

    

I am interested in taking this answer and posting it to my .Net Web API for user registration / login.

I was wondering how I would format the HTTP request from my client and what the method in AccountController.cs would look like to handle the request correctly and pass back a local token that will be used throughout the rest of the application.
