Using googleOAuth without sessions: is it possible to send information about the user; whether he's a newly created user or an existing one, back to the client?

I'm using passport-google-oauth20 without sessions since this backend will be used for mobile too. When hitting the strategy callback I can either create a user if he doesn't exist and send that profile back, or if he does exists, simply send that user back.However, on the client side, I will be redirecting a user to different routes depending on whether he's a brand new user or an existing one. How can I send this info from the strategy callback, back to the client? Is this possible?
