Secure API Endpoint with Bearer Token Authentication and Field Validation

Say goodbye to insecure or messy webhook inputs! ✨

This automation acts as a secure entry gate for your n8n workflows—validating incoming requests, checking for required fields, and returning clean, standardized JSON responses. It's the perfect lightweight authentication and validation layer for public APIs or form integrations.

Perfect for developers, no-code builders, and anyone exposing n8n workflows as APIs.

What it does:

🔐 Verifies Bearer Token in the Authorization header
✅ Validates presence of all required fields in the request body
📦 Returns clean JSON responses:

401 Unauthorized if the token is missing or incorrect

400 Bad Request if required fields are missing

200 OK with your custom payload if validation succeeds

✅ Setup guide & importable automation included

Need to add rate limiting, IP filtering, or dynamic tokens? We offer advanced customization and support for a one-time setup fee.
