webhook-signature-verifier-api
Server-side helper to check webhook authenticity: validates HMAC-SHA256 signatures the way common providers do (Stripe Stripe-Signature, GitHub X-Hub-Signature-256, or a raw digest). Clients POST the shared secret, exact raw payload string, and header value; the API returns whether the signature matches, with optional Stripe replay-window checks. Stateless, no persistence, no third-party APIs.
