      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. 

      Responses for different cases

      This section provides responses for different cases of failed refunds.

      1. The refund currency is inconsistent with the transaction currency.

      The refund currency needs to be consistent with the transaction currency, otherwise an error is returned. The following example is a sample code of this case.

      2. The refund currency exceeds the refund limit.

      For example, the refund amount exceeds the transaction amount or is less than the minimum refund amount. The following example is a sample code of this case. 

      3. The refundRequestId is repeated.

      The ​​refundRequestId ​​ is same with the previous request. The following example is a sample code of this case. 

      4. The transaction status is invalid.

      If initiates a refund in non-SUCCESS status, an error is reported. The following example is a sample code of this case. 

      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 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= 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.
