Overview

The API endpoints for the live and sandbox servers are:

Live: https://api.peachpayments.com/v1/checkout/refund
Sandbox: https://testapi.peachpayments.com/v1/checkout/refund

Perform a refund against a successful payment by referencing the unique payment ID provided in the payment status request or in the successful payment webhook.

Perform the refund by sending a POST request over HTTPS to the API endpoint. The POST request must contain the authentication parameters, the initial payment ID, the payment type (RF), refund amount, and currency.

The content-type header must be `application/x-www-form-urlencoded` or `application/json`. # Parameters
