About the development of payment, recommend to see the official documents and source code. I wasted a lot of time just because I didn't read the document carefully. Please refer to the development of payment (PHP):

Determine if the order has been updated before the return XML and the updated order is not processed directly

The most direct is to download the official demo run to see if there is a problem and then against your own code to see that step problem

You need to give the address of a callback, and then post it to the data to get on the line should be XML format you yourself parse

If the notification is repeated, ignore it directly.
