Create unreferenced refund

Use this method to create an unreferenced refund. An unreferenced refund is a refund that isn’t linked to a bank transfer payment. **Note:** If you have the paymentId of the payment you want to refund, use our [Refund Payment](https://docs.payroc.com/api/schema/bank-transfer-payments/refunds/refund) method. If you use our Refund Payment method, our gateway sends the refund amount to the customer’s original payment method and links the refund to the payment. In the request, you must provide the customer’s payment method and information about the order including the refund amount. In the response, our gateway returns information about the refund and a refundId, which you need for the following methods: - [Retrieve refund](https://docs.payroc.com/api/schema/bank-transfer-payments/refunds/retrieve) – View the details of the refund. - [Reverse refund](https://docs.payroc.com/api/schema/bank-transfer-payments/refunds/reverse-refund) – Cancel the refund if it’s in an open batch.
