# Getting Started
> Set up Vero tracking in your application. Install the SDK, identify users, and start tracking events in minutes.
## Prerequisites
Before you begin, you'll need:
* A Vero account ([sign up here](https://getvero.com/get-started) if you don't have one)
* Your **Tracking API key**, found on the [Settings page](https://connect.getvero.com/settings/project/tracking-api-keys) of your Vero account
## Choose your integration method
Recommended for websites and front-end applications.
For React, Node.js, and other JavaScript build environments.
For server-side integrations in any language.
Ruby, PHP, and other community-maintained libraries.
## Install the JavaScript SDK
Add the following to the `` section of every page you want to track, replacing `` with your API key. You can find your Tracking API key on the [Settings page](https://connect.getvero.com/settings/project/tracking-api-keys) of your Vero account.
```html theme={null}
```
This SDK is also available as [an NPM package](https://www.npmjs.com/package/@getvero/tracking) for advanced use cases (e.g., integrating in React or Node.js applications). Refer to the package's README for more information.
## Identify a user
When a user logs in, call `user.identify` with their `id` and `email` (both required). This adds or updates the user in your Vero data store.
```javascript theme={null}
vero.tracker.user.identify({
id: "",
email: ""
})
```
You can also attach additional channels and custom data to the user profile:
```javascript theme={null}
vero.tracker.user.identify({
id: "",
email: "",
phone_number: "",
channels: [
{
type: "push",
address: "",
platform: "android"
}
],
data: {
first_name: "",
last_name: ""
}
})
```
The `phone_number` property stores a phone number against the user's profile and is used as the delivery address for SMS messages sent via Journeys. Similarly, the `channels` array is used to register push tokens so Vero can deliver push notifications to the user's device.
Once identified, users will appear in the **Profiles** section of your Vero account where you can view their properties, channel addresses, and activity history. Learn more about [user profiles](/vero-2/user-profiles/understanding-user-profiles).
## Track an event
An event represents a user action in your application, such as viewing a product or completing a purchase.
```javascript theme={null}
vero.tracker.event.track({
eventName: "viewed product",
data: {
product_name: "Red T-shirt",
product_url: "https://www.example.com/products/red-t-shirt",
}
})
```
You must call `user.identify` before calling `event.track`, unless you supply an `identity` object to the method. Once you call `user.identify`, the SDK stores the `id` and `email` in local storage for future requests.
Tracked events will appear on the **Events** page in your Vero account, where you can view recent occurrences, event properties, and which campaigns use each event as a trigger. Learn more about [events in Vero](/vero-2/events/events-overview).
## Unidentify a user
When a user logs out, call `user.unidentify` so future events are not associated with them.
```javascript theme={null}
vero.tracker.user.unidentify()
```
