ImplementedEvent-Driven CRM Integration
I implemented a voice-to-CRM event service with HMAC-verified webhooks, replay-window checks, tenant-scoped idempotency, duplicate detection and recovery after simulated downstream outages.
What I built
- Implemented HMAC signature and timestamp verification for event ingestion.
- Implemented tenant-scoped event fingerprints, duplicate responses and explicit conflict rejection.
- Implemented a simulated downstream outage with queued events and a reconciliation endpoint.
Experiments & checks
- Duplicate event ID must not apply another write.
- Same event ID with a different payload must be rejected.
- A CRM outage must leave a recoverable queued event.
- Cross-tenant updates must be denied before the CRM call.
Notes & limitations
I built the webhook receiver and mocked CRM event pipeline around duplicate delivery, replay windows, downstream outages and reconciliation.
Webhook callers require verification, tenant scope and a bounded replay window. Never accept a tool-generated tenant ID as authority.
Exactly once is not something you get for free because someone put a webhook in a slide deck.
