Your Stripe webhook is a doorman.

If it never checks the signature, it signs for anyone in a delivery vest, and one fake "payment succeeded" gets them Pro.

A URL isn't a password.

If your Stripe webhook skips the signature check, anyone can POST a fake "checkout.session.completed" to your server, and your app hands out Pro.

How it happens + the 3-step fix 🧵

[Aster @TheAsterCo]

Save this:
1. Verify the signature (constructEvent)
2. Use the raw body
3. Handle each event ID once
4. Give Pro only for verified events
5. Test with stripe listen + stripe trigger

Which one did your app skip?
