We're developing a system whereby the user will be sign-up and have a 3 month trial without entering card details. Once the trial period is up they get sent an e-mail asking them to come back and register card details in order to setup a recurring payment in order to continue accessing the site.
Is it possible to configure recurring payments with Braintree such that we don't provide a card for the trial period and then configure one upon notification that it has expired?
Thanks!
