Create pre-authorization

Pre-authorization (pre-auth) allows you to place a temporary hold on a card for predetermined time periods. The pre-authorized amount is available to capture or refund.
Example: Hotels and car rental companies authorize the initial cost of the service but may capture a different amount where additional charges are required if a guest uses the hotel minibar or a rental car is damaged.
The pre-auth validity depends on the transaction and card type.
Example: Pre-auth for Mastercard^® expires in 30 days and for Visa^® in 7 days.
