Refund

What payment methods are eligible for synchronous refunds?

Different payment methods have different payment properties:

• Alipay+ payment method: Synchronous refund. When the refund API is called, the refund result is returned immediately.
• Non-Alipay+ payment method: Asynchronous refund. When the refund API is called, a "processing" status is returned first. The refund result is to be synchronized later through an asynchronous notification once the refund is completed.

Why does Grabpay SG return a failed result when making a same-day refund?

The final state of a failed refund may be attributed to the following reasons:

• Grabpay relies on the settlement of payment methods. A refund request cannot be processed if the settlement is incomplete.
• The balance of the account to be settled is insufficient.
• The order payment was not successful.

It is recommended that you provide the refundRequestId value and contact Antom Technical Support to troubleshoot the failed reason.

If I initiate a refund request for less than 50 KRW in Kakao Pay, will Antom reject the transaction?

Yes, Antom will reject the refund request, and you will not be able to initiate another refund request at that time.

After calling the refund API, resultStatus returns U. When retrying without changing the number, are there any requirements for the retry interval and number of retries?

You can reduce the frequency of retries over time. It is recommended to use the following retry intervals: 2 minutes, 10 minutes, 10 minutes, and 1 hour.

Why don't I receive a refund notification when the refund API call is successful and returns a SUCCESS status?

The refund processes include synchronous refund or asynchronous refund across different payment methods.

• Synchronous refund: After calling the refund API, the response directly indicates whether the refund was successful or failed. In this case, you will not receive a refund notification.
• Asynchronous refund: After calling the refund API, a response indicates the refund is in process. You are then required to periodically check the refund status or wait for a notification that will provide the final refund status.
