Note: Subscriptions do not process transactions in real-time. Creating a subscription transaction successfully does not guarantee that subscription payments will process through your account successfully. Subscription transactions process at approximately 2:00 a.m. PST on scheduled payment dates. Therefore, the first scheduled transaction is not sent to the customer’s bank for authorization until approximately 2:00 a.m. PST on the start date that you specify when you create the subscription in your account. If you create a subscription with a start date that equals the creation date, the first scheduled payment does not process until after 2:00 a.m. the following day. If you wish to validate your customer’s payment information before creating their subscription in your account, use one of the real-time transaction processing methods available through the API.

Navigate to, here we can find all API documentation. But before using this API, we have to set up “ SDK”  as per your programming language.

We can also download it from here:
