# Validate Auth0 JWT tokens in n8n via webhook with 200/401 responses
This workflow enables secure authentication for incoming API requests in n8n by validating JWT tokens issued by Auth0. It checks the token signature and returns standard HTTP status codes — 200 OK on success, 401 Unauthorized on failure. Designed for technical users who need to protect their endpoints without exposing private keys.
## Who it´s for
- Developers integrating n8n with Auth0 for secure authentication
- Administrators of self-hosted n8n instances requiring JWT validation without access to private keys
- Security engineers setting up protected API endpoints in n8n
## What the automation does
- Receives HTTP requests containing a JWT token via webhook
- Validates the token signature using either JWKS URI (via jwks-rsa) or a built-in public certificate
- Decodes the token payload upon successful validation
- Returns 200 OK with decoded data or 401 Unauthorized on error
- Acts as part of a secure API gateway within n8n
## What´s included
- Ready-to-use n8n workflow with JWT validation logic
- Webhook trigger configuration
- Integrations with Auth0 and Webhook API
- Basic text instructions for setup and adaptation
## Requirements for setup
- Self-hosted n8n instance with external npm packages enabled
- Access to Auth0 (to obtain JWKS URI or public signing certificate)
- Installed dependency: `jwks-rsa` (when using JWKS method)
- Basic knowledge of Node.js and code nodes in n8n
## Benefits and outcomes
- Enables secure authentication for n8n-based APIs
- Eliminates the need to store or use private keys
- Supports two validation methods: dynamic (JWKS) and static (certificate)
- Reduces risk of unauthorized access to workflows
- Simplifies integration with existing Auth0-powered systems
- Complies with OAuth 2.0 and OpenID Connect security standards
