# How to Ensure Upstack Data Theme App Extension is Enabled

> Enable the Upstack Data theme app embed in your Shopify theme editor so the tracking pixel loads on every storefront page and captures events server-side.

<Tip>
  * In Shopify Admin, navigate to **Online Store → Themes → Customize**
  * Click the **App embeds** icon in the theme customizer
  * Enable **UpStackified Pixel** and click **Save**
  * **Verify** with a test purchase
</Tip>

<Note>
  For your tracking events to fire correctly in Shopify, you need to ensure the **UpStackified Pixel** Theme App Extension is enabled in your live theme. Once complete, we recommend a test purchase to verify conversion tracking is working properly.
</Note>
