Provider field mapping

Public URLhttps://your-subdomain.instatunnel.my/webhooks/twilio
Local portUse the port from your local app command.
Success checkVerify X-Twilio-Signature and reject mismatched callback URLs.

Failure fixes

If the provider cannot reach the endpoint, confirm the local app is running and restart the tunnel with the same subdomain.

If events arrive but fail verification, compare the exact public URL and signature secret configured in the provider dashboard.

If retries create duplicates, store the provider event ID before performing side effects.
