Webhook Processing Architecture Pattern

“Draw a webhook processing architecture with third-party provider, public webhook endpoint, signature validation layer, event store, queue, idempotent worker, business service, retry scheduler, dead-letter queue, and monitoring. Show the fast ack path separately from background processing.”

Scenario summary

A system that receives third-party webhook events, validates signatures, stores an event record, pushes work into a queue, and processes updates idempotently with retries and dead-letter handling.

Why this architecture matters

• 1

  Webhook systems often fail in the details around retries, ordering, and idempotency, and a diagram makes those paths easier to inspect.

• 2

  It helps teams separate the fast acknowledgement path from background processing and downstream side effects.

• 3

  It is useful for payment, billing, and integration docs because it shows where validation and event records live.

Refine it with follow-up prompts

After generating the base diagram, use these prompts to iterate and add detail — the same way a real architect would refine a whiteboard sketch.

• 1

  “Add replay tooling for failed events and indicate where deduplication keys are stored.”

  Try this follow-up
• 2

  “Show ordering-sensitive events and which handlers can process in parallel.”

• 3

  “Add alerting path when retries exceed the safe threshold.”
