Stripe Webhook Signature Invalid on Replit

Stripe webhook calls are rejected with signature verification error. Webhook handler rejects all incoming events.

Signature verification requires exact configuration and secret key matching.

Error Messages You Might See

Signature verification failed No signature header found Timestamp outside tolerance window
Signature verification failedNo signature header foundTimestamp outside tolerance window

Common Causes

  1. Wrong webhook secret (signing key) configured
  2. Using test secret in production or vice versa
  3. Timestamp header missing from validation
  4. Request body modified/corrupted in transit
  5. Signature header format incorrect

How to Fix It

Verify webhook signing secret from Stripe dashboard matches app config. Use separate test and live keys. Use Stripe's official SDK for signature validation. Include timestamp tolerance (within 5 minutes). Ensure request body is raw (not JSON parsed) before validation. Check Stripe logs for which endpoints are configured.

Day job: I'm the sole backend developer at merketing company where I own and maintain 11 PHP/Symfony microservices on AWS (ECS Fargate, RDS, S3, CloudFront), handle the full CI/CD pipeline (Bitbucket Pipelines, Docker), and manage monitoring with Sentry and CloudWatch. These services handle high request volumes in production every month. What I bring to AI-built apps: - I audit and fix security issues (OWASP methodology), performance bottlenecks, and architectural problems in codebases generated by Cursor, Claude Code, Lovable, Bolt, and v0 - I refactor AI-generated prototypes into production-grade applications with proper error handling, testing, and clean architecture (SOLID, DDD, hexagonal architecture) - I set up the infrastructure AI tools don't touch: AWS hosting, CI/CD pipelines, automated deployments, database optimization, monitoring, and alerting - I integrate external services: payment providers, email systems, partner APIs, SSO/auth Tech stack: PHP 8.x, Symfony, React, Next.js, PostgreSQL, MySQL, Docker, AWS (ECS, RDS, S3, SQS/SNS, CloudFront), Terraform, Supabase. I also use AI tools daily (Claude Code, Cursor) in my own workflow, so I understand both the strengths and the gaps in AI-generated code. Based in Poland (CET timezone).
