Secure n8n API: Bearer Token Auth & Field Validation
Reusable n8n workflow that secures public webhooks with Bearer Token authentication, validates required fields, and returns standardized JSON responses for 401, 400, or 200 status.
This production-ready n8n workflow protects public webhook endpoints by verifying Bearer Tokens from the Authorization header against a configurable secret. It then dynamically validates that all specified fields are present in the request body, ensuring data integrity before processing.
Key features include centralized configuration for tokens and required fields, standardized error responses (401 Unauthorized for invalid tokens, 400 Bad Request for missing fields), and a customizable 200 OK s
