patch https://api.sandbox.cleeng.com/3.1/payments//cancel
To cancel a payment, you use a payment resource.
Payments at Cleeng are a reference to the actual payment that happens at the payment gateway or in-app store.
To cancel a payment, make a PATCH request to the /3.1/payments/{paymentId}/cancel endpoint where paymentId is the reference of the payment you want to cancel.
Please note that you can use this endpoint to cancel a payment that has been authorized but not captured yet. (For more information about payment authorization and capture, see here).
Cancelling a payment means that the payment is not processed any further.
