High-Level Use Case

1. Order Service → sends a message to OrderPaymentRequestTopic requesting payment.

2. This ServiceBusListener picks up the message:

3. Reads order & card details.

4. Calls the payment gateway to process the payment.
5. Marks the message as completed.
6. Publishes the payment result to OrderPaymentUpdatedTopic, which other services (like Order Service) can consume to update the order status.
