Pay-In Callback

• When order has been paid, Server will sent a callback to your server
• Requests use http-form-post encoding application/x-www-form-urlencoded
• Gateway : notify_url uploaded in Create request paramters
• If you need create a order with money of 100.00, and your client paid 30.00, this order is also considered as failure(cheatting), no callback will be send
• when you sucessfully start a test order, you can ask service man to send a test-callback for you, but the money will be set to zero, because you don't actually paid for this order
• you can use postman to test your callback url like this, we will send notification in the same form
