Zalify's app pixel in Shopify Customer events
How Zalify tracks visits, checkouts and purchases through Shopify's Customer events, how to check it's connected, and what to do when Zalify asks you to re-authorize Shopify.
Shopify doesn't run app JavaScript on checkout, and it has retired the Additional scripts box on the thank-you and order status pages. Checkout and purchase tracking now goes through Shopify's Customer events.
How Zalify uses Customer events
Zalify connects to Customer events as an app pixel, through Shopify's Web Pixels API. It records visits, product views, checkouts and purchases, which Zalify's attribution and ad conversions are built from.
Once your store has granted Zalify the pixel permissions, Zalify installs the app pixel for you. You don't add a custom pixel or paste any code.
Check that it's installed
Open Customer events
In Shopify admin, go to Settings → Customer events.
Find Zalify
Open the App pixels tab, find Zalify and confirm its status is Connected.
If Zalify isn't listed
Your store hasn't granted the permissions the app pixel needs. Zalify then shows a banner, Re-authorize Shopify to install the Zalify Web Pixel, on Home, Attribution, Orders and Visitors.
Start the re-authorization
Click Re-authorize Shopify in the banner.
Approve in Shopify
Shopify lists the permissions Zalify needs. Approve them.
Check Customer events
Zalify installs the app pixel. It appears under Settings → Customer events → App pixels.
Until you re-authorize, some orders can't be attributed. If you don't see the banner and Zalify still isn't listed, contact Zalify support.
A few stores need Zalify installed as a custom pixel instead. If that's you, contact the Zalify team and we'll set it up for your workspace. Don't paste scripts from unknown sources into Customer events: they can double-count your events.
Also set up
- Turn on the theme app embed. The app pixel records events, but Zalify's popups, forms and browser-side ad pixels run on your storefront through the Zalify Pixel app embed. See Install the Zalify Pixel on Shopify, and Shopify is retiring script tags if your store installed Zalify before April 2026.
- Remove old tracking code from Additional scripts or your theme so events aren't counted twice. See How to cleanly remove legacy third-party Pixels code.
- Connect your ad platforms. In Zalify, click Pixel in the left sidebar, choose a platform such as Meta, Google Ads or TikTok, and click Add Pixel. See Send conversions to Meta, Google, TikTok & more.
Verify
Open your store in Preview Mode, add a product to the cart or place a test order, and confirm the events fire. See Test your setup with Preview Mode.
