Refund

Overview

This page will show you how to initiate a refund. A refund should be used once the transaction you are refunding has settled. If you are trying to cancel a transaction that is still in the currently open batch, you should void the transaction instead. By default, this endpoint will perform a full refund on a given transaction. However, partial refunds are possible by including the optional amount parameter field.

The API endpoint is as follows:

POST /api/v2/transactions
