It is possible to refund credit card transactions. In fact, this works much the same way as refunding an iDEAL transaction.
It is also possible to only partly refund a transaction, for instance, when the customer has returned part of an order, or when part of the order cannot be delivered. In that case, you fill out the amount to be refunded to the customer. In these cases, the transaction costs will be applied.
Please take note: a credit card refund cannot be undone.
The refund option can be found in your transactions overview. Look up the transaction and click on 'refund'.
