After the payment is completed, PayerMax will send the relevant payment results to the merchant in the form of data flow. After receiving it, the merchant should process it and respond according to the document specifications.
1.Notification Specification
The same notification may be sent to the merchant system repeatedly. The merchant system must be able to handle duplicate notifications correctly.
During the backend notification interaction, if PayerMax receives the merchant response which does not conform to the specifications or overruns, PayerMax will determine the failure of the notification and re-send the notification until it succeeds (Currently, PayerMax will issue multiple notifications at most 6 times in interval 0s/30s/300s/600s/3600s/43200s).
In case the order status is unknown or PayerMax payment result notification has not been received, it is suggested that merchants actively call theof PayerMax to confirm the order status.
