Cancel after payment (refund)

You can refund up to the amount of the received payment. To do this you have to make a cancel transaction on the charge transaction.


  "amount" : "12.450",
  "paymentReference": "Test cancel transaction"
$unzer = new Unzer('s-priv-xxxxxxxxxx');
$charge = $unzer->fetchChargeById('s-pay-1', 's-chg-1');
$cancel = $charge->cancel();
Unzer unzer = new Unzer(new HttpClientBasedRestCommunication(), "s-priv-xxxxxxxxxx");
Charge charge = unzer.fetchChargeById("s-pay-1", "s-chg-1");
Cancel cancel = charge.cancel();
