SaaS Failed Logistics Jobs: Python Queue Retries, Cron Audits, and Dead Letters

Managing delayed webhooks in a Node.js SaaS requires clear boundaries between scheduling and delivery. The recommended approach is to use a message queue for per‑delivery retries and enforce idempotency, while reserving cron jobs for periodic reconciliation rather than as the primary delivery clock. This separation ensures reliable fan‑out workflows where a single order update reaches many subscriber endpoints without duplicate processing.
