Designing Resilient Webhook Ingestion with FastAPI, Celery, and Redis
Third-party webhooks from payment gateways (Stripe), communication providers (Twilio, RingCentral), or healthcare EHR integrations are notoriously unpredictable. Providers will retry aggressively during network blips, send duplicate payloads, or blast thousands of events within seconds during batch syncs. If your webhook endpoint directly executes database queries or third-party downstream calls, your backend will quickly encounter connection exhaustion, cascading timeouts, and 504 Gateway errors. Here is the architectural blueprint I use to design high-throughput, idempotent webhook ingestion pipelines. ...
