Stripe webhook signature missingNo signatures found matching the expected signaturewebhook signature verification failed
What it means
The app trusts webhook JSON before verifying Stripe-Signature against the raw body.
Most common causes
- Body parser consumes raw body
- Wrong webhook secret
- Preview endpoint secret reused in production
- AI generated code updates paid state from client
Fastest fix
- Reproduce the smallest failing case.
- Check environment, platform, and production settings.
- Use the related local tool to classify the issue.
- Fix the highest-risk security or data issue first.
Safe fix
- Keep secrets out of client code and logs.
- Prefer least privilege and explicit allowlists.
- Add a regression test or checklist before retrying.
- Document the working production configuration.
What not to do
- Do not disable security controls as a permanent fix.
- Do not paste secrets into public issue trackers or AI chats.
- Do not trust preview success as production readiness.
