AuthorizationReverse Class

The AuthorizationReverse class processes the IPCAuthorizationReverse method. It allows you to cancel a pre-authorized amount before the funds are captured — essentially releasing the hold on the customer’s card.

Use this when the transaction is no longer needed (e.g., canceled bookings, out-of-stock items, expired pre-auths).

$reverse->setOrderID('AUTH-ORDER-20250410')
        ->setCurrency('EUR')
        ->setAmount(50.00); // You can reverse full or partial amount

if ($reverse->validate()) {

    echo "Authorization successfully reversed.";
} else {
