A transaction is eligible for a refund only after it has been successfully paid. Multiple partial refunds are allowed, but the total refunded amount must not exceed the original transaction amount. For multiple partial refunds, only one refund request for the same transaction may be in progress at any given time; the next refund can only be initiated after the current one has been completed.
This is a synchronous issuance API. Upon successful order issuance, the API will immediately return the Acquiring Refund Result Resource (including core order information such as order number, amount, and initial status).
In addition, if the order status changes subsequently (e.g., from READY to PAID, FAILED, or REFUNDED), the system will send a webhook notification to the merchant’s pre-configured webhook endpoint. The notification payload follows the structure defined in the Acquiring Order Webhook Data Resource.
