Order system of middle office

Order system

As a middle stage , The docking system is strange
I understand that there are positive orders and abnormal orders

Positive order , The user saw the product , Place an order , Rating , payment , Delivery of goods
Abnormal order , It's a timed mission , Orders accessed by third parties , For example, the renewal of third-party joint membership ,
The third-party platform has completed the transaction , Notify this platform , This platform first delivers products and accounts （ Each family is divided into different ）

Payment system

The payment system is also divided into 2 Schools , Apple and the domestic payment system
Alipay and WeChat , Are waiting for callback , They will notify the server , Then deliver the goods
Apple got the certificate on the mobile phone , Upload , Then the server takes the certificate to verify , Passed , You can deliver
