# Refund callback

If you have configured callbacks, pawaPay will `POST` a callback to your configured callback URL for each refund when it reaches a final status.
Read more about [handling callbacks](/implementation#handling-callbacks) and [callback URLs](/using_the_api#callback-urls).

If you have not configured callbacks, you can always call our [Check Refund Status](/v1/api-reference/refunds/check-refund-status) endpoint to get the latest status and details of a specific refund request.

### Headers

  Following headers are only included if you have enabled signed callbacks.
