Manage PayPal payment
Manage PayPal transactions
Manage paymentsAfter the successful charge or authorize transaction, you can perform additional operations on the payment resource. Some of the important ones are described in the following section.
For a full reference of managing payments, go to relevant server-side integration documentation page: Manage API resources (direct API calls), Manage API resources (PHP SDK), or Manage API resources (Java SDK).
Cancel before money receipt (reversal)
To reduce or cancel a reservation on the customer account, perform a cancel on the initial transaction. An example of reversal would be unblocking the reserved amount on the customer account after they returned a rented car.
POST https://api.unzer.com/v1/payments/s-pay-1/authorize/cancels
{
"amount" : "20.00"
}
$unzer = new Unzer('s-priv-xxxxxxxxxx');
$payment = $unzer->fetchPayment('s-pay-1');
$unzer->cancelAuthorizationByPayment($payment, 20.00);
Unzer unzer = new Unzer("s-priv-xxxxxxxxxx");
Authorization authorization = unzer.fetchAuthorization('s-pay-1');
Cancel cancel = authorization.cancel();

You can refund up to the amount of the received payment. To do this, make a cancel transaction on charge(s) received via notification.

{
"amount" : "20.00",

}
$unzer = new Unzer('s-priv-xxxxxxxxxx');
$charge = $unzer->fetchChargeById('s-pay-1', 's-chg-1');
$cancel = $charge->cancel();
Unzer unzer = new Unzer("s-priv-xxxxxxxxxx");
Cancel cancel = unzer.cancelCharge("s-pay-1", "s-chg-1");
