This project consists of a payment notification queue. When a payment for an order is successfully made, an object is placed in the queue for processing and sending the notification to the partner.
The flow starts when an order is paid.
After payment of the order, another system will send the number of the paid order to the queue.
When the order is added to the queue, this function will start.
- Each added order will have its existence verified in the customer order table;
- Then a notification will be sent to the partner's api informing that the order has been released and is ready to be used.
Requires an sqs object to start.
