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
Common Causes
- Wrong webhook secret (signing key) configured
- Using test secret in production or vice versa
- Timestamp header missing from validation
- Request body modified/corrupted in transit
- 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.

I've scaled systems, automated deployments, and built observability tools for AI coding workflows. I specialize in taking vibe-coded apps from broken prototype to production-ready: fixing Supabase auth/RLS, Stripe integrations, deployment pipelines, and cleaning up AI-generated spaghetti.
I build tools in this space (agentprobe, claudebin, micode) and understand both sides: how AI generates code and why it breaks.
