Shopify Scripts Are Being Removed — Here's What You Need To Do Before June 30

If you're running a Shopify Plus store and you've been using Shopify Scripts to handle custom discounts, payment gateway rules, or shipping logic at checkout, this one's for you: Shopify Scripts will stop working entirely on June 30, 2026.

Even more pressing — starting April 15, 2026, you won't be able to edit or publish any Scripts. So if you haven't started planning your migration, it's now or never.

What's replacing Scripts?
Shopify Functions. Think of them as the modern, significantly more powerful successor. Where Scripts ran in a sandboxed Ruby environment with limited capabilities, Functions are compiled WebAssembly modules that execute natively within Shopify's infrastructure.

 They're faster, more secure, and cover far more ground than Scripts ever did.

Functions support everything Scripts handled — line item discounts, payment customizations, shipping rules — but also unlock new capabilities like cart transforms, checkout validation, delivery customizations, and order routing. These were simply not possible with Scripts.

What should you do right now?

1. Check the Scripts Customizations Report
   Head to your Shopify admin and look for the Scripts Customizations Report. Shopify generates this automatically and it maps out all your active Scripts, organized by type (payment, shipping, product discounts). It even recommends replacement apps built on Shopify Functions.
   
   
2. Audit and categorize
   Go through each Script and decide: Is this still in use? Is it something a public app can handle? Or does it need a custom Function to be built? This saves you from blindly rebuilding logic you no longer need.
   
   
3. Start migrating in stages
   Don't try to rewrite everything at once. Group your Scripts by type — discounts first, then shipping, then payments — and migrate one group at a time. The good news is that Scripts and Functions can coexist in the same store until the deadline, so you can test progressively without breaking anything.
   
   
4. Test on a dev store first
   Always. Especially for complex discount logic or wholesale pricing rules. Functions have a different input data structure than Scripts, so edge cases might behave differently.

One important note
If you're on a standard Shopify plan (not Plus), you can still use public apps from the App Store that are built with Shopify Functions — you just can't deploy custom Functions via a private app. That's a Plus-only feature. So for most merchants, the transition might be as simple as switching to a recommended app from the customizations report.

Why this matters
This isn't just a maintenance task. Migrating to Functions is also an opportunity to clean up legacy checkout logic that's been accumulating over the years. If you've ever stacked multiple Scripts on top of each other to handle various promotions, you'll know exactly what we mean. Functions give you a chance to rebuild that logic cleaner, faster, and with a more maintainable architecture.

The June 30 deadline is firm — Shopify has already extended it once (it was originally August 2025) and has been clear there won't be another extension. Don't wait until June to figure this out.
