PED adjust an existing Pre-auth
Pre-auths allow you to reserve funds in advance of a future transaction and can be generated whether the cardholder is present or the cardholder is not present. During this time, while no funds have actually left the customer's bank account, these reserved funds are unavailable to spend. You can view current pre-auths by navigating to Guest Journey, Billing, then GuestPay pre-auths. The pre-auth can be adjusted, completed or cancelled after generating the pre-auth. If no action is taken on the pre-auth, the reserved funds are automatically released back to the cardholder after 30 days or for Amex cards 7-10 days depending on the acquirer.
⚠️Important: Amex card pre-auths cannot be adjusted. This feature is not supported by AMEX.
To adjust an existing pre-auth, follow the steps below:
On the main screen, tap the Menu icon (3 horizontal lines) and select Adjustment.
Enter the new pre-auth total amount and select the Tick.
Enter the Auth code (located on the merchant receipt or shown on the MYST token under Transaction), and press Tick.
Enter the Sequence code (located on the merchant receipt or shown on the MYST token under Acquirer within Acquirer transaction ref), and press Tick.
Once successfully adjusted, the receipts will print. Keep these receipts as they will be needed for completion or cancellation.
You have up to 30 days, or for Amex cards 7-10 days depending on the acquirer, to complete the transaction before the reserved funds are automatically released back to the customer.
