#More information

This section gives additional information about certain parameters. See the following list for details:

refundRequestId:

Alipay uses the refundRequestId parameter for idempotency control. For example, if the refund request with the refundRequestId of 201811291907410200070000001111 has been successfully processed by Alipay, when the merchant uses the same refundRequestId to refund, Alipay returns a result of refund success.
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 is U.

refundId

The parameter can be used for the refund inquiry.

#Result

#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 merchant can call Refund Result Inquiry 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= REFUND_WINDOW_EXCEED). If the refund is still needed 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. Merchant can retry with the same refundRequestId.
