Verifying Webhook Signatures Securely
Protect your payment backend from forged events by validating Stripe webhook signatures and following secure endpoint practices.
Why Verify Webhooks?
Your webhook endpoint is public. Without verification, an attacker could POST a fake payment_succeeded event and unlock paid features for free.
The Signing Secret
Each webhook endpoint has a signing secret (starts with whsec_). Stripe uses it to sign every event it sends you.
