Cancel pre-auth (or cancel pre-authorization) is the process of releasing a temporary hold on funds placed on a customer's payment method before the final transaction is completed.Important Notes:
You can only cancel a pre-authorization if the transaction is still pending; if the pre-auth has already been completed or previously cancelled, it cannot be cancelled again.
Each transaction’s pre-authorization can be cancelled only once.
Once the cancellation is successfully processed, the transaction status will update to "CANCELLED."
For ABA PAY and Card transactions, funds are instantly released back to the payer, whereas for KHQR transactions, the funds will be refunded to the payer.
