Message Queue Timeout Issues in Delayed Webhook Delivery for Node.js

Fintech systems must manage delayed webhook delivery using bounded consume timeouts and dead-letter queues to prevent distorted available balances or inventory. Using Amazon SQS with workers allows for safe reservation expiry prompts. Additionally, implementing a two-stage pipeline for shipment fan-out ensures events are validated and normalized into a canonical envelope before entering the delayed queue. This architecture protects latency-sensitive subscribers from malformed payloads by logging schema versions and delivery attempts at the fan-out boundary.
