More information
This section gives additional information about the key parameter. See the following list for details:
- refundRequestId:
The refund can be full or partial. A transaction can have multiple refunds as long as the total refund amount is less than or equal to the original transaction amount. If being out of the refund window, the refund request will be declined. Use the same refundRequestId to retry a refund in case of timeout or when the returned resultStatus isU. - refundId:
The parameter can be used for the refund inquiry.
Result process logic
For different request results, different actions are to be performed. See the following list for details:
- If the value of result.resultStatus is
S, for synchronous refund, the refund succeeds. For an asynchronous refund, the refund request is processed successfully and the merchant can call the inquiryPayment interface to query the refund result. - If the value of result.resultStatus is
F, the refund fails. Usually, the failure is caused by a refund initiated outside the refund window (result. resultCode=FREFUND_WINDOW_EXCEED). If the refund still needs to be processed, manual intervention is needed. - If the value of result.resultStatus is
U, the result is unknown. Processing failure might occur due to system or network issues. The merchant can retry with the same refundRequestId.
