Transaction Refund

caution

Transaction Refund can only be performed when a transaction has been charged/settled and is in a CHARGE state. Any transaction which is not yet settled/charged should be cancelled via the Transaction Reversal function.

You will encounter scenario where it is required to refund a consumer; Either for the full transaction amount in the case of a return of goods, or in some cases for a reduced amount such as a gesture of goodwill. Our Gateway solution allows you to manage this yourself using the tokenId, but this requires additional integration effort.

To simplify the process, our Checkout solution has the ability for a merchant to perform a refund against the transaction id, removing the requirement to store the consumers tokenId. The refund request can be for any value up to the value of the original transaction. Only one refund can be processed against each id and therefore if additional refunds are required to be made these will have to be completed using the token, via the the Gateway.
