Secure Seatable Webhook Validator with HMAC SHA256

This workflow secures Seatable webhook integrations by verifying HMAC SHA256 signatures. It listens for incoming requests, computes a hash of the raw body using a shared secret, and compares it against the x-seatable-signature header. Valid requests proceed with a 200 OK response and trigger downstream processing; invalid ones get a 403 Forbidden.

Benefits include robust protection against tampering and unauthorized access, essential for sensitive data in finance or IT systems. It saves time by providing a ready template, reducing custom coding risks and ensuring compliance with security best practices.

Use cases: Integrate with financial apps for secure transaction notifications, IT incident alerts, or any Seatable-powered automation needing webhook security. Duplicate and customize by adding nodes after verification for actions like data processing or notifications.
