# Setting Up HubSpotUTK Cookie Tracking
The `hubspotutk` cookie is set by HubSpot's tracking script and stores a unique visitor token used for contact attribution. By calling HubSpot's `identify` method from Spara's JavaScript API `onUserMessageSent()` event, you can associate a visitor's session with their HubSpot contact record.
### Prerequisites
* The **HubSpot tracking script** is installed on your site. [Hubspot's guide to install the tracking code.](https://knowledge.hubspot.com/reports/install-the-hubspot-tracking-code)
* The [**Spara embed script**](/guides/installation-guides/readme/installing-spara-navigator.md) is installed on your site.
### Add the identify call
Use Spara's `onUserMessageSent()` event (see [Javascript API](https://docs.spara.com/developers/spara-api/javascript-api)) to extract the visitor's email. Then, call `identify` to merge the visitor to the hubspot cookie data and `trackPageView` to push the identity to HubSpot.
<script type="text/javascript" src="https://app.spara.co/embed-<app_id>.js"></script>
<script>
Spara = {
onUserMessageSent: function (text) {
// extract email from user message
function extractEmail(text) {
const match = text.match(/[a-zA-Z0-9._%+-]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,}/);
return match ? match[0] : null;
}
const email = extractEmail(text);
if (window._hsq && email) {
window._hsq.push(["identify", { email }]);
window._hsq.push(["trackPageView"]);
}
},
}
</script>
**Note:** `identify` sets the identity in HubSpot's tracker memory only. A separate `trackPageView` or `trackEvent` call is required to actually send the data to HubSpot.
### Single-page application (SPA) setup
If your site uses Next.js or React, page navigations don't trigger full reloads, so HubSpot won't automatically track route changes or send identity data.
1. Follow the identify call instructions above.
2. Create a `HubSpotPageView.tsx` component to call `trackPageView` on every route change:
```tsx
'use client';
import { usePathname } from 'next/navigation';
import { useEffect } from 'react';
export default function HubSpotPageView() {
const pathname = usePathname();
useEffect(() => {
if (window._hsq) {
window._hsq.push(["trackPageView"]);
}
}, [pathname]);
return null;
}
```
3. Add it to your root layout (`app/layout.tsx`):
```tsx
import HubSpotPageView from './HubSpotPageView';
{children}
```
