Reliable Service Integration
summary
A Symfony-based checkout is integrated with a mock payment API and a RabbitMQ producer/consumer pipeline; an initial implementation causes an infinite requeue loop that is fixed by adding a dead-letter queue with TTL and implementing exponential backoff so the payment gateway recovers. The demo uses a WebSocket for user feedback, measures a 21-second eventual delay, and demonstrates that combining a queue with a retry policy reduces user-facing rate-limit failures when working with third-party payment services.
