# Klaviyo Webhooks & Events
## Overview
Set up Klaviyo webhooks with HMAC-SHA256 signature verification, event routing, idempotency handling, and the Webhooks API for programmatic subscription management.
This skill covers the full endpoint lifecycle in six steps: create a webhook subscription via the API, verify each request's signature, receive events in an Express handler, route them to per-topic handlers, deduplicate with Redis, and manage subscriptions. The high-level flow and the security-critical signature check live here; the complete step-by-step source is in [references/implementation.md](references/implementation.md) and worked scenarios are in [references/examples.md](references/examples.md).
## Prerequisites
- Klaviyo account with webhooks enabled
- HTTPS endpoint accessible from internet
- API key with scopes: `webhooks:read`, `webhooks:write`
- Redis or database for idempotency (recommended)
