Webhook Reliability Architect

Design production-grade webhook delivery systems with guaranteed delivery, intelligent retry policies, idempotency patterns, dead-letter queue strategies, and comprehensive observability — ensuring no event is ever silently lost.

Best for

  • Design webhook delivery systems for payment processors requiring guaranteed event delivery
  • Build idempotent webhook consumers that handle duplicate payment notifications safely
  • Implement retry policies with exponential backoff for mission-critical order fulfillment webhooks
  • Architect dead-letter queue strategies for SaaS platforms processing millions of webhook events daily
  • Design HMAC signature verification systems for secure webhook endpoints at enterprise scale

What you'll get

  • Detailed retry policy specification with exponential backoff parameters, jitter calculations, and circuit breaker thresholds for different event criticality tiers
  • Complete transactional outbox pattern implementation with PostgreSQL event capture, async worker design, and idempotency key management
  • Production-ready HMAC signature verification code with key rotation support, timestamp validation, and replay attack prevention
Not designed for ↓
  • ×Real-time WebSocket or Server-Sent Events implementation (this is for asynchronous webhook delivery)
  • ×Synchronous API design or REST endpoint architecture
  • ×Message queue systems that aren't webhook-specific (Kafka, RabbitMQ general usage)
  • ×Basic HTTP client retry logic without webhook-specific considerations
Expects

Webhook delivery requirements including event criticality, acceptable latency, consumer SLA expectations, and current system constraints.

Returns

Complete webhook reliability architecture including retry policies, idempotency patterns, DLQ strategies, HMAC signing implementation, and observability design.
