Validate Auth0 JWT Tokens using JWKS or Signing Cert

🔐 Say goodbye to insecure API endpoints!

This automation lets you securely validate Auth0 authorization tokens in incoming API requests — even when the standard JWT option won’t work. It uses custom Node.js logic inside n8n to handle RS256-based token verification after the webhook is triggered.

Whether you're securing webhooks or building protected APIs, this tool keeps your data safe and Auth0-compliant.

What it does:

🛡️ Validates Auth0 JWT tokens using JWKS or signing certs
🧠 Uses code node to verify RS256 tokens post-webhook
🚧 Redirects invalid tokens to a 401 response (without stopping the workflow)
📦 Supports both JWKS URI and imported signing cert options
✅ Setup guide & importable automation included

Note: Requires a self-hosted n8n instance with npm support and access to your Auth0 app’s JWKS or signing certificate.
