# Refunds

A [captured](https://docs.commercelayer.io/core-api-reference/captures) payment can be refunded, either totally or partially. The total refund amount cannot exceed the amount captured — if it’s equal to the amount captured the refund will be full, if it’s less the refund will be partial:

* In case of a **partial refund**, the related order's payment status is moved to `partially_refunded` and a new successful refund transaction is created.
* In case of a **full refund**, the order status is moved to `cancelled`, its payment status to `refunded`, and a new successful refund transaction is created.

A refund process can be initiated via trigger attribute either from an [order](https://docs.commercelayer.io/core-api-reference/orders) or from a [return](https://docs.commercelayer.io/core-api-reference/returns#refunding-from-a-return). The response you get when you fetch a refund contains all the information and messages provided by the [payment gateway](https://docs.commercelayer.io/core-api-reference/payment_gateways).

If a refund gets stuck (for any reason) on our platform but succeeds on the payment gateway, you can [unblock](https://docs.commercelayer.io/core-api-reference/transactions#unblocking-stuck-transactions) it by passing the `_forward` trigger attribute.
