Refund a Payment

Suggest Edits

Refunds allow you to refund a previous transaction to the original instrument from where the purchase was made.

How it works

Utilising our refunds feature you are able to refund an amount up to the value of the full transaction amount utilising the original payment transaction ID and reference number.

Multiple refunds are able to be processed on the transaction up to the original transaction amount.

Refunds can only be processed on payments made using the purchase flow or after a transaction using the pre-authorisation flow has been completed.

Refund a Payment

Using the transactionId and optionally the paymentTransactionRef from a payment you are able to refund a transaction up to the amount of the original transaction. You can simply call this method with the transactionId and all subtransactions will be refunded for their full amounts or you can specify the sub-transactions paymentTransactionRef and the amount you wish to refund the transaction for.
