Introduction

Via a refund an amount previously charged via the authorization or the capture request is credited (e.g. to the customer's credit card or the customer's account).

The payment request that is booked in the transaction account during this request is negative and therefore reduces the amount of the total payment request sum. This request can only be carried out if the balance of the transaction account is settled.
