# How it works: Shopify to Attentive

## What you can track

All events below are being sent [server-side](/get-started/how-server-side-tracking-works.md) and are tracked by default. You can choose to disable tracking for one or multiple events within the app settings.

| **Event name** | **Description**                        |
| -------------- | -------------------------------------- |
| Add to Cart    | When a user adds a product to the cart |
| Product Viewed | When a user views a product            |

## Event properties

Our schema is designed to be backwards compatible with the standard Add to Cart and Product Viewed events from Shopify

In addition to this, Littledata adds `externalIdentifiers` to improve the linking of on-site behavior to an Attentive profile.
