# Testing

> Test your webhook integration before going to production

Thoroughly test your webhook integration to catch issues before they affect users.

## Test in Development

Use the Smartcar Dashboard to trigger test webhook deliveries.

<Steps>
  <Step title="Set up local tunnel">
    Use ngrok or similar to expose your local server:

    ```bash theme={null}
    ngrok http 3000
    ```

    This creates a public HTTPS URL that forwards to your local development server.
  </Step>

  <Step title="Configure webhook">
    In the Smartcar Dashboard, set your ngrok URL as the callback URI (e.g., `https://abc123.ngrok.io/webhooks/smartcar`)
  </Step>

  <Step title="Verify webhook">
    Complete the VERIFY challenge to activate the webhook
  </Step>

  <Step title="Trigger test events">
    Use the Dashboard to send test `VEHICLE_STATE` and `VEHICLE_ERROR` events to your endpoint
  </Step>

  <Step title="Verify handling">
    Check logs to confirm:

    * Signature verification works
    * Payload is queued successfully
    * Processing logic executes correctly
    * Idempotency prevents duplicates
  </Step>
</Steps>
