Everything for working with Svix webhooks: first-time setup (API key, SDK install, first message), Dispatch (sending webhooks to your customers), Ingest (receiving third-party webhooks), Applications, Channels, customer UIDs, idempotency, App Portal embedding, operational webhooks, the Svix CLI, and — only when the user explicitly asks for one — a written integration plan (repo investigation, tenancy design, event type catalog, migrating off an existing webhook system). Use whenever you add, review, modify, or debug a Svix integration. For a robust webhook receiver that isn't Svix-specific, use receiving-webhooks.

General guidelines for building a robust webhook receiver/handler: verifying signatures, raw-body access, replay protection, async processing, retries and endpoint auto-disabling. Use whenever you write, review, or debug a handler that consumes incoming webhooks from any provider.
