Release v1.2.3 (Part 1) - Cancel at end of Pay Period
One feature that many users have asked for is the ability to delay the cancellation of subscriptions until the end of the pay period. This especially comes in handy when you have a product that customers pay for in advance.
You can now accomplish this in Chargify via the Admin Interface as well as the API. For more info, check out the relevant docs:
Cancellation UI: http://docs.chargify.com/cancellation
Subscription Update API: http://docs.chargify.com/api-subscriptions (see the cancel_at_end_of_period option for updates)
