description	Receive and verify Svix webhooks (the Standard Webhooks scheme used by many providers). Use when setting up a Svix webhook handler, debugging svix-id / svix-timestamp / svix-signature verification, handling secret rotation with multiple signatures, or parsing the {"type": "...", "data": {...}} envelope for events like invoice.paid, user.created, or message.sent.

Svix Webhooks

Svix is webhook-sending infrastructure used by many upstream services. If a provider delivers webhooks "powered by Svix" (or implements the Standard Webhooks spec), the verification below applies regardless of who the sender is.

When to Use This Skill

• How do I receive Svix webhooks?
• How do I verify svix-id / svix-timestamp / svix-signature headers?
• Why is my Svix webhook signature verification failing?
• How do I handle secret rotation (multiple v1, signatures in one header)?
• My provider says webhooks are "powered by Svix" / "Standard Webhooks" — how do I verify them?
• How do I parse the {"type": "...", "data": {...}} event envelope?

Verification (core)

Each request carries three headers:

svix-id: msg_2b1c...            # unique message id
svix-timestamp: 1614265330      # Unix seconds
svix-signature: v1,g0hM9SsE...  # space-delimited "v1,<base64 sig>" entries
