I've a free plan among some other plans. when user signup with Free Plan I create the Account in RECURLY without subscription & Billing Information. When user tries to upgrade to some paid plan. I create a subscription. But with subscription, I also need to set the Billing account token in 1 Request, How i can do that in Recurly using Ruby on rails.
if account.present && subscription.blank?
recurly_result =subscription.update_attributes(subscription attributes & Account billing token)
end
