Shopify Scripts and the Script Editor stop working on June 30, 2026. If your store runs Scripts for discounts, shipping, or payment logic at checkout, that code will simply stop executing after that date. With the deadline at the end of June 2026, this is the moment to act.
Here is exactly who is affected, what breaks, and what to do.
Who is affected
Any store using Shopify Scripts, the Ruby scripts written in the Script Editor app. Scripts were a Shopify Plus feature, so if you are on Plus and have ever set up automatic discounts, shipping rate rules, or payment method rules through the Script Editor, this is you.
Not sure if you use Scripts? Open the Script Editor app in your admin. If you see active scripts there, they need to be migrated. We also wrote a short guide on how to tell if your store still uses Shopify Scripts.
What breaks on June 30, 2026
After the cutoff, your Scripts stop running. Concretely, that can mean:
- Discounts vanish. Automatic discounts driven by a Script (tiered spend thresholds, returning-customer rewards, free gifts) stop applying. Customers pay full price.
- Shipping rules revert. Rates you were hiding, renaming, or reordering go back to the default set, so options you deliberately removed reappear.
- Payment rules revert. Methods you were hiding or reordering show up again in their default order.
None of this throws an error. It just silently stops, which is exactly why it is dangerous: you may not notice until margins or conversion move.
What replaces Scripts
Shopify Functions. Functions are small programs you write in JavaScript or Rust that run on Shopify's own infrastructure during checkout. They are faster than Scripts, version-controlled, testable, and available well beyond Plus. They are also the only supported way to customize the new checkout, which is where every store now lives.
Each Script type has a direct replacement:
- Discount Scripts become discount functions.
- Shipping Scripts become delivery customization functions.
- Payment Scripts become payment customization functions.
What to do, in order
- Open the Script Editor and list every active Script and what it does.
- Map each one to its Function using the links above, or the full migration guide.
- Rebuild and test in a development store. Functions ship as part of an app, so you will use the Shopify CLI.
- Deploy, verify in a live checkout, then delete the old Script so the two never conflict.
- Do it now. Every Shopify developer is fielding this same migration right now, and availability tightens as June 30 approaches.
Short on time?
With the deadline this June, the safest move is to get it done by someone who has migrated Scripts before. Caffeine and Commerce migrates Shopify Scripts to Functions, tested and live, before the cutoff. Send us your Script Editor list and we will handle every rule.
