Shopify is forcing an upgrade on all non-Plus stores by August 26, 2026. After that date, the legacy Thank You and Order Status pages are gone for good, and whatever you've got sitting in the "Additional Scripts" box just stops running.
Good. It should stop running.
Plus stores already went through this. As of August 28, 2025, their Additional Scripts and checkout.liquid became view-only, and PII access on the legacy pages got locked down. Shopify started auto-upgrading the stragglers in batches starting January 2026, with each store getting 30 days' notice before its pages got force-replaced and every existing customization wiped for good.
Non-Plus stores get one deadline this August 26, 2026. Miss it, and Shopify upgrades you automatically with no extra warning beyond whatever's already sitting in your admin.
What's actually in that Additional Scripts box is usually some combination of:
A conversion pixel for Meta, Google, or an affiliate network
A GTM container someone installed years ago and forgot about
A custom thank you message or order note display
Sticking a pixel in a script tag has always been fragile. One Shopify update, a browser change, or an ad blocker can kill your data without you even knowing it. You end up stressing over tanking numbers and blaming your ads, only to realize later that your campaigns were fine it was just your tracking falling apart the whole time.
So if this deadline breaks your setup, it's not creating a new problem. It's just surfacing one that was already there.
What replaces it
Shopify isn't leaving you with nothing. Instead, it's swapping open-ended script injection for three narrower tools:
Web pixels for browser-side tracking, run in a sandboxed environment instead of loose on the page.
App pixels, which can run server-side instead of in the browser. Shopify's own documentation says server pixels "can increase the amount of customer events...that are transferred to app owners," because they don't depend on cookies or a browser tab staying open.
Note: App and custom pixels only track with customer consent, which Shopify says can mean fewer recorded events than the old scripts that fired regardless. If your Additional Scripts pixel was tracking every visitor no matter what they'd consented to, you were probably overcounting before, not undercounting now.
Two things that will break if you don't catch them
The Thank You page URL is changing from
/checkouts/<id>/thank_youto/checkouts/<id>/thank-you. Any hardcoded tracking URL or redirect rule pointing at the old slug needs updating.If you're on a custom domain, your customer accounts domain has to move to a subdomain (like
account.yourstore.com), or pixels and cookie consent won't work on the Order status page at all.
Checking where you stand
Go to Settings > Checkout > Configurations. If there's a banner prompting you to upgrade, you're still on the legacy pages. Click it and Shopify hands you a personalized guide listing exactly which apps and scripts need replacing before you hit "Upgrade."
If you pause your store before August 26, your pages upgrade immediately whether you are ready or not.
If you're already using Aimerce, none of this touches you. Your purchase data doesn't depend on a script loading in someone's browser or surviving an ad blocker, so there's nothing on this deadline for you to fix.
If your tracking is already server-side some other way, this email changes nothing for you. If it's not, now you know why the number on your dashboard might move in three weeks for reasons that have nothing to do with your ads.
