NOTIFICATION

Http method： post
Content-type: application/json
Automatic re-send functionality:
We also provided automatic re-send functionality. If a delivery fails the first time, we will automatically attempt to send it 3 more times, with an exponentially growing timeout between attempts, as per the list below:

• 5 minutes
• 10 minutes
• 15 minutes
  After 3 attempts, the delivery will be marked as Failed. At this point, it is worth checking your configuration before asking your Solutions Manager to manually re-send the notification.
  When receiving notifications, you must use the notification key to verify the signature of the received notification. However, you do not need to sign the response to the notification.
  Notification key:
• If you use the notifyurl in the transaction request, please use the Notification key of the master merchant.
• If you want to receive the notification at sub-merchant level, please setup the sub merchant's notifyurl in the portal.
• If you want to receive the notification at master merchant level, please only setup the master merchant's notifyurl in the portal.

Response：After successfully receiving the notification, please return the response in the following format.

{
    "code": "000000"
