Order

📄️ Create a new order

Merchant Server establish order information then send to Zalopay Server to create order.

📄️ Query status of an order

1. When the payment is `successful`, Zaloay will call the callback (notify) to the Merchant, then the Merchant updates the status of Successful orders on the Merchant's system. But in reality, the callback may be missed due to Network Timeout / Merchant Service Unavailable / Internal Error,... so Merchant needs to make the call of the API to query the order status.
