Quick start pattern
Command
instatunnel webhook init --provider twilio --port 3000 --path /webhooks/twilioPublic endpoint example
https://your-subdomain.instatunnel.my/webhooks/twilioFailure 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.
