Webhook Ingestion Pipeline
Event ProcessingProductionIntegration platformMulti-source webhook receiver with signature validation, rate limiting, Kafka fan-out, and dead-letter alerting. Suitable for building reliable event intake from third-party platforms.
Recommended for: Teams ingesting third-party webhooks at scale
Scope Notes
Intended for Teams ingesting third-party webhooks at scale at Production complexity and Integration platform scope. Treat the graph as a starting shape rather than a fixed stack: keep the topology and the signals below, then swap providers to match your platform.
Review Checklist
Use Case
Webhook handlers, event ingestion, third-party integrations
Best Fit Scenarios
- Platforms receiving events from many vendors
- Operations that need failed deliveries surfaced
- Teams enforcing rate limits at the edge

Why This Topology Works
The gateway receives from GitHub and Stripe, the rate limiter absorbs abusive bursts, and Kafka durably buffers events before consumers process them. Failures are parked in the DLQ and surfaced in Slack rather than dropped.
Scaling Notes
Kafka partitions by source so consumers scale with traffic. The audit log in PostgreSQL records what was received, and the Slack alert path is the escalation surface for the DLQ.
Observability
Per-source delivery success is reconstructed from the audit log. DLQ depth is the on-call signal, and consumer lag shows whether processing is keeping up with ingest.
Typical Bottlenecks
- Bursty delivery from vendor retry storms
- Duplicate deliveries without idempotency keys
- Consumer lag during source retries
Async Flow and Reliability
Webhooks are accepted and buffered in Kafka, then processed by consumers. Failures do not block the partition: they route to the DLQ and page the owner through Slack.
Upgrade Path
Add signature verification in front of the rate limiter and an idempotency store keyed on delivery id, then add a replay worker that drains the DLQ after fixes.
