# Ninetailed Web Device Mode Integration

{{< info >}}
RudderStack recommends sending events to Ninetailed in device mode over the cloud mode.
{{< /info >}}

After you have successfully instrumented Ninetailed as a destination in RudderStack, follow this guide to correctly send your events to Ninetailed in [device mode]({{< ref "/destinations/rudderstack-connection-modes.md#cloud-mode" >}}).

Find the open source transformer code for this destination in the [GitHub repository](https://github.com/rudderlabs/rudder-sdk-js/tree/develop/packages/analytics-js-integrations/src/integrations/Ninetailed).

{{< info >}}
In web device mode, RudderStack uses the native [Ninetailed SDK](https://docs.ninetailed.io/for-developers/experience-sdk/sending-events) to send the events.

As mentioned in the [Setup Guide]({{< ref "destinations/streaming-destinations/ninetailed/setup-guide.md" >}}), you need to [install the Ninetailed SDK](https://docs.ninetailed.io/for-developers/experience-sdk/getting-started) as an npm package before sending the events.

## Identify

You can use the [`identify`]({{< ref "event-spec/standard-events/identify.md" >}}) call to send a [`identify`](https://docs.ninetailed.io/for-developers/experience-sdk/sending-events#identify) event to Ninetailed.

A sample `identify` call is as shown:

```javascript
rudderanalytics.identify("12345", {
  firstname: "Alex",
  city: "New Orleans",
  country: "USA",
  phone: "8005550100",
  email: "alex@example.com"
})
```

### Supported mappings

RudderStack maps the following properties to the corresponding Ninetailed fields:

| RudderStack property | Ninetailed property | Data type |
| :----| :----| :-----|
| `userId` | `userId` | String |
| `traits` | `traits` | Object | 

## Track

You can use the [`track`]({{< ref "event-spec/standard-events/track.md" >}}) API to send a [`track`](https://docs.ninetailed.io/for-developers/experience-sdk/sending-events#track) event to Ninetailed.

A sample `track` call is as shown:

```javascript
rudderanalytics.track("Product Reviewed", {
  review_id: "86ac1cd43",
  product_id: "9578257311",
  rating: 3.0,
  review_body: "Good product."
});

You can use the [`page`]({{< ref "event-spec/standard-events/page.md" >}}) call to send a [`page`](https://docs.ninetailed.io/for-developers/experience-sdk/sending-events#page) event to Ninetailed.
