| description | Receive and verify Vercel Log Drains deliveries. Use when setting up a Vercel log drain HTTP endpoint, debugging x-vercel-signature verification, handling the x-vercel-verify endpoint handshake, or processing batched log entries from sources like lambda, edge, build, static, external, firewall, and redirect.

Vercel Log Drains Webhooks
Vercel Log Drains forward deployment logs to any HTTPS endpoint you configure.
These are HTTP log-drain deliveries (not "Vercel webhooks" and not Standard
Webhooks): Vercel POSTs batches of log entries and signs the raw body with
HMAC-SHA1.
When to Use This Skill
- How do I receive Vercel Log Drains?
- How do I verify the
x-vercel-signature header?
- How do I complete the
x-vercel-verify endpoint handshake?
- Why is my Vercel log drain signature verification failing?
- How do I parse batched log entries (JSON array or NDJSON)?
- How do I handle logs from
lambda, edge, build, or firewall sources?
Verification (core)
Vercel signs the raw request body with HMAC-SHA1 keyed on your drain's
signature secret and sends the digest in the
header (the raw digest — no prefix). Use the body (do not
re-serialize), and compare timing-safe.
