Node.js Express webhook subscriber guide: honoring 429 Retry-After with idempotent queue retries

A new guide for logistics background job queues explains how a Node.js Express push subscriber should handle HTTP 429 responses. It recommends honoring the Retry-After header, parsing it as seconds or an HTTP date, and rescheduling deliveries with jittered exponential backoff when the header is absent. Idempotency keys on every shipment event are presented as the way to prevent duplicate dispatches after timeouts or visibility-timeout races. The article also suggests tenant-scoped circuits and dead-letter review so one noisy integration does not exhaust worker capacity, and advises acknowledging incoming webhooks quickly with a 202 response while performing outbound calls asynchronously.
