Webhook Reliability Framework

Webhook delivery with retry, deduplication and a dead-letter queue.

Webhooks are the backbone of real-time integrations, but they are inherently unreliable. Our framework adds automatic retry, dead-letter queues, deduplication, and end-to-end monitoring.

核心创新

Persist Before Acknowledge

Every webhook event is persisted before acknowledgment. Failed deliveries retry with exponential backoff up to configurable limits.

Deduplication

Idempotency keys prevent duplicate processing when marketplaces send the same event multiple times during retries.

Dead-Letter Queue

Events that exhaust retry limits land in a dead-letter queue for manual investigation and replay.

Real-Time Monitoring

Dashboard showing delivery rates, latency percentiles, error patterns, and queue depths across all connected platforms.

技术细节

PostgreSQL-backed persistent queue with ACID guarantees
Exponential backoff with jitter (1s → 2s → 4s → ... → 24h max)
SHA-256 based idempotency key generation
Per-marketplace rate limiting to respect API quotas
Prometheus metrics export for Grafana dashboards
Automatic alerting via email and Slack for queue anomalies

常见问题

What happens to events in the dead-letter queue?

Dead-lettered events can be inspected in the monitoring dashboard, manually replayed after fixing the underlying issue, or automatically discarded after a configurable retention period. You receive alerts when events enter the DLQ.

Does this work with all marketplace webhooks?

Yes. The framework is platform-agnostic and works with any webhook-capable service. It handles the reliability layer so individual connectors can focus on business logic.
