Fix “Additional Scripts Deprecated”: Setup Shopify Custom Pixel Data Layer
January 31, 2024
Shopify’s Checkout Extensibility Update is deprecating “Additional Scripts” — and breaking many stores’ tracking in the process. Here’s how to fix it using Shopify’s Custom Pixel + Data Layer pattern.
What changed
Shopify is migrating all checkout customization to Checkout Extensibility. The legacy “Additional Scripts” field is gone for new stores and being phased out everywhere.
The fix
Use Shopify’s Custom Pixel feature (Settings → Customer Events) to deploy your Data Layer and tag manager. It’s sandboxed, future-proof, and works with both client- and server-side GTM.
Why this matters for tracking
If you relied on Additional Scripts to push the purchase Data Layer on the Thank You page, you lost it. Custom Pixel restores that — and unlocks server-side tracking too.
