Having a bit of trouble figuring this one out. How would you verify a user is who they say they are, when they are using your RESTful api and Google + Login for initial auth, while keeping your API stateless. This is what I have thought up:

The issue is, what does the user send to my RESTful api server after my server has gotten its long term tokens.
I'm probably missing something very obvious here
