  Request: POST /payments/{paymentPspReference}/refunds
  Summary: Refund a captured payment
  Description: Refunds a payment that has been [captured](https://docs.adyen.com/api-explorer/#/CheckoutService/latest/post/payments/{paymentPspReference}/captures), and returns a unique reference for this request. You get the outcome of the request asynchronously, in a [**REFUND** webhook](https://docs.adyen.com/online-payments/refund#refund-webhook).

You can refund either the full captured amount or a part of the captured amount. You can also perform multiple partial refunds, as long as their sum doesn't exceed the captured amount.

> Some payment methods do not support partial refunds. To learn if a payment method supports partial refunds, refer to the payment method page such as [cards](https://docs.adyen.com/payment-methods/cards#supported-cards), [iDEAL](https://docs.adyen.com/payment-methods/ideal), or [Klarna](https://docs.adyen.com/payment-methods/klarna). 

If you want to refund a payment but are not sure whether it has been captured, use the [`/payments/{paymentPspReference}/reversals`](https://docs.adyen.com/api-explorer/#/CheckoutService/latest/post/payments/{paymentPspReference}/reversals) endpoint instead.

For more information, refer to [Refund](https://docs.adyen.com/online-payments/refund).
