Changes the date or the amount of one scheduled payment. No money moves.

A scheduled payment is a planned future collection on an instalment, subscription or metered order. It shows as one billing event in the order's payment timeline.

• A new scheduled_at sets the status back to scheduled. A declined payment is then collected on the new date.
• The date change is recorded on the order. The customer may get an email about the new date.
• A new amount is used for the next collection, in the payment's own currency. You can't change the currency.
• Fields you leave out stay as they are. An empty scheduled_payment changes nothing.
• status and failed_attempts are ignored if you send them. The request still succeeds.

You can change a payment that is scheduled, failed (soft declined) or rejected (hard declined). A payment that is complete, in review, merged, recovered, skipped or cancelled can't be changed.

To change the date or amount again, send another request.
