OmniAuth::Strategies::GoogleOauth2AccessToken is simply a Rack middleware.

A brief example, using the middleware in a Rails application at config/initializers/omniauth.rb:
Rails.application.config.middleware.use OmniAuth::Builder do
provider :google_oauth2_access_token, ENV['GOOGLE_CLIENT_KEY'], ENV['GOOGLE_CLIENT_SECRET']
endRequest the access_token to the provider, then login via ajax GET/POST call to /auth/google_oauth2_access_token/callback while providing access_token parameter.
