preauthExpireLogic	number	Field for the logic of blocking payment with pre-authorization 0 - If there is no request for confirmation or cancellation, payment will be confirmed upon expiration of the lock on the side of the acquirer bank (~114 hours after creating the payment) 1 - If there is no request for confirmation or cancellation, payment will be cancelled upon expiration of the lock on the side of the acquirer bank (~114 hours after creating the payment). If the parameter is not used, the payment will be cancelled after the expiration date.
