google app - gdata4ruby

Hi,

I am integrating google app -docs and calender and for that I am using authsub API and gem gdata .My existing user will sign up with google account for google service so I need to sent custom variable like user id with authsub request URL and response is token.Is it possible to get token along with custom variable(user id)?

Thank you

Here is a tutorial (its sinatra) about getting oauth token from google apps.
