Secure Webhook with Authentication and Validation

This n8n workflow creates a secure webhook endpoint that authenticates incoming POST requests using a Bearer token and validates that all required fields are present in the request body. It responds with standardized JSON messages for success, missing authorization, or missing fields, ensuring only trusted and well-formed requests are processed. The workflow begins with an incoming webhook, checks the authorization header against a configured token, validates request payload fields, and then either passes through to further processing or responds with appropriate errors. This setup is useful for developers or organizations needing a protected API endpoint for forms, integrations, or third-party services, ensuring data integrity and security.
