Trigger a charge on an active ADHOC subscription. The API call initiates the payment — the actual payment outcome (success, failure, or cancellation) is delivered asynchronously via webhooks, at which point the order and payment records are created in the system.
This endpoint only supports ADHOC subscriptions. The subscription must have an active mandate before a recurring payment can be triggered.
Amount to charge for this recurring execution. If not provided, the subscription’s billing_amount is used. Must be less than or equal to the subscription’s billing_amount.
