# Session IDs Explained

How Recart uses the Session ID on your orders to attribute revenue accurately.

Once you install Recart, you'll notice a **Session ID** being added to the notes section on your order pages. This is completely normal — it's how Recart tracks orders and calculates your attributed revenue accurately.

#### Why is a Session ID added to orders?

From the point you have Recart installed, a **Session ID** is added to each store visit and order. This doesn't mean every order is attributed to Recart — the ID simply helps our app identify which Shopify order belongs to which **Recart subscriber**, which is how **attributed revenue** is **tracked accurately**.

If the app can't identify a Recart subscription from the ID, the sale won't be attributed, but the Session ID will still be visible on the order page.

#### Seeing a Shopper ID on an older order?

Recart previously added a Shopper ID to orders alongside the Session ID. This was phased out in July 2026 and is no longer added to new orders. Orders placed before then may still show a Shopper ID — this is expected, and it's safe to ignore. It doesn't affect your Session ID, your tracking, or your revenue attribution.
