Subscription FAQs

1. How can we identify the subscription plan the user paid for - from the webhook response? ANS: The payment code returned in the webhook response would be the same as the code on the subscription link.

2. If a subscription charge attempt fails, will it be retried in the next billing cycle? ANS: Yes, until the number of expected payment cycles is completed— we retry in the next billing cycle.
