Introduction

It is recommended that merchants verify if an order is eligible for a refund before processing it, to avoid duplicate refunds or order in non-refundable statuses (e.g., in payment processing).
If the status does not support a refund, an error code will be returned. See Return Code List for details.

Refund order supported all token and network for payment.
