Modifications

Refund a captured payment

Refunds a payment that has previously been captured, returning a unique reference for this request. Refunding can be done on the full captured amount or a partial amount. Multiple (partial) refunds will be accepted as long as their sum doesn't exceed the captured amount. Payments which have been authorised, but not captured, cannot be refunded, use the /cancel method instead.

Some payment methods/gateways do not support partial/multiple refunds. A margin above the captured limit can be configured to cover shipping/handling costs.

For more information, refer to Refund.

This endpoint is inactive and is no longer supported for new integrations.

If you are building a new integration, use the Checkout API /payments/{paymentPspReference}/refunds endpoint instead.

If you have an existing integration using this endpoint, reach out to your Adyen contact and migrate to the Checkout API.

The Checkout API enables your online payments integration to accept all supported payment methods, use the latest features, and access more benefits.
