​
Send a test event

You can test your webhook directly from the Allo dashboard:
1

Open your webhook settings

Go to Settings > Webhooks in your Allo dashboard.
2

Select an event to test

Pick any event type from the catalog (e.g., call.completed, sms.received) and click Test.
3

Check the result

Allo sends a synthetic event to your endpoint and shows whether it succeeded, the HTTP status code returned, and the response time.

​
Local development

During development, your webhook endpoint is typically not publicly accessible. Use a tunnel service to expose your local server:
1

Start your local server

Run your webhook handler locally (e.g., http://localhost:3000/webhooks/allo).
2

Create a tunnel

Use a tool like ngrok to expose your local server:
ngrok http 3000
This gives you a public HTTPS URL (e.g., https://abc123.ngrok.io).
3

Configure your webhook

Go to Settings > Webhooks and set your tunnel URL as the endpoint.
4

Send a test event

Use the test feature above to trigger a delivery and verify your handler processes it correctly.

​
Monitoring

Check your webhook health from Settings > Webhooks. You can see delivery statistics including successful, pending, and failed deliveries. A healthy webhook should have a low failure count relative to successes. If failures are increasing, check Troubleshooting.
