post https://api.payment.sandbox.coinify.com/v1/payment-intents//refunds//cancel
This endpoint allows you to cancel a previously created refund. It is only possible to cancel refunds before a destination address has been provided for it. Once the refund is in the destination_provided [state] (https://coinify.readme.io/reference/payment-intent-resource#merchantrefunds) it is not possible to cancel it.
Work in progress
