Why this kit comes first
Stripe webhook failures block payments, automations, fulfillment, subscriptions, and customer lifecycle events.
The expensive mistakes
- Verifying a decoded or re-encoded JSON body.
- Using a CLI `whsec_` value for a Dashboard endpoint.
- Using a Dashboard endpoint secret for a CLI-forwarded event.
- Reading the wrong header name in PHP or WordPress.
The fix path
- Verify the raw request body before parsing.
- Confirm the endpoint that sent the event.
- Use the matching `whsec_` secret.
- Return a fast `2xx` only after signature verification passes.
