notifyRefund
Antom uses this API to send the refund result to the merchant when the refund processing reaches a final state of success or failure. Merchants promote merchant-side transactions based on the refund result.
Structure
A message consists of a header and body. The following sections are focused on the body structure. For the header structure, see:
Note: Set the data type of each field (except array) as String. This means that you must use double quotation marks (" ") to enclose the field value. Examples:
- If the data type of a field is Integer and its value is 20, set it as "20".
- If the data type of a field is Boolean and its value is true, set it as "true".

Result process logic
Send the following message with fixed values to Antom after receiving the notification, to acknowledge that the notification from Antom is received:
If no such message is returned to Antom due to operation issues or network issues, Antom will resend the notification until the required message is returned by the merchant. Resending of the notification will be performed within 24 hours after the first notification is sent. The notification will be resent up to eight times, with an interval of 0s, 2min, 10min, 10min, 1h, 2h, 6h, and 15h.
