  Integrating payments into a modern application requires strict adherence to security protocols. When building a Node.js payment integration, developers frequently encounter the   Stripe webhook signature failed   error. This occurs when the application attempts to validate incoming webhook events from Stripe but the cryptographic signatures do not match. This error is an immediate blocker. If your server cannot verify the signature, it must reject the request to maintain FinTech API security. This prevents malicious actors from spoofing payment events and granting unauthorized access to your platform's resources. The solution lies entirely in how Express handles incoming HTTP request bodies. By default, standard middleware modifies the request stream before Stripe's SDK can validate it. The Root Cause: Payload Mutation and Cryptographic Hashes Stripe signs its webhook events using a Hash-based Message Authentication Code (HMAC) with SHA-256. When Stripe dispatches an ev...
