Shopify deadlines calendar
Every dated Shopify platform change we know of that affects merchants or their apps, in one list: what happens, how many days are left, who it affects and what to do. Each date links to Shopify’s own page for it. The page is rebuilt every day, and the days left are counted from the date shown above the list. We checked every date on 8 November 2026.
Upcoming Shopify deadlines
Days left are counted from 9 November 2026, when this page was last built. It is rebuilt every day.
Add these dates to your calendarBulk operations need an IP allowlist
3 days left
Who it affects: App developers
Public apps that run bulk queries or mutations must have an IP allowlist, a list of the addresses allowed to call the API. Without one, their bulk operations fail after this date. Custom apps and apps merchants create themselves are not affected.
What to do
App developers: add your app’s IP addresses to its allowlist now. Merchants: if an app syncs your whole catalogue or order history, ask its vendor whether it is ready.

Public apps without an IP allowlist are delisted
11 days left
Who it affects: App developers
All public apps need an IP allowlist, not only those that run bulk operations. From this date, public apps without one are delisted from the Shopify App Store and blocked from new installs.
What to do
App developers: set the allowlist before this date. Merchants: if an app you use disappears from the App Store, ask its vendor why before you renew or build on it.

Public apps must use expiring access tokens
53 days left
Who it affects: App developers
Public apps still on non-expiring offline access tokens are delisted from the App Store and blocked from new installs. Existing installs keep working until 1 April 2027. Custom apps and apps merchants create are not affected.
What to do
App developers: migrate to expiring offline access tokens now, because Shopify says the later dates are not extra time. Merchants: ask each public app’s vendor, in writing, whether they have migrated.

The Knowledge Base app is retired
67 days left
Who it affects: Merchants
Shopify’s knowledge base for AI agents now sits in the admin, under Sales channels > Agentic. The standalone Knowledge Base app is no longer available after this date.
What to do
If you used the app, check your facts moved across. Stores with more than 1,000 facts need to add the ones they want to keep by hand before this date.

Admin warnings for apps on old tokens
67 days left
Who it affects: Merchants
If you use a public app that still relies on non-expiring tokens, your Shopify admin shows a warning that the app’s service may be interrupted.
What to do
Contact the app’s vendor as soon as the warning appears, and line up a replacement in case they can’t fix it before 1 April 2027.

Last day for API version 2026-01
68 days left
Who it affects: App developers
Shopify serves version 2026-01 of its APIs until 15:00 UTC on this date. After that, a request for it is answered by the oldest supported version instead, which can change what an app gets back.
What to do
App developers: move API calls and webhook subscriptions to a newer version and test them before this date. If your store has a custom app, ask whoever maintains it which version it uses.

Old app tokens stop working
143 days left
Who it affects: Merchants and app developers
Admin API calls made with non-expiring offline access tokens return an error, so a public app that hasn’t migrated can no longer read or write your store’s data. Custom apps and apps merchants create are not affected.
What to do
Replace any public app whose vendor hasn’t confirmed the move to expiring tokens. App developers: this is when calls start failing, not an extension of the 1 January 2027 deadline.

Apps can no longer create script tags
Who it affects: App developers
Requests to create or update a script tag return an error. Script tags already on a store keep loading until 1 March 2027.
What to do
App developers: ship storefront code as an app embed block in a theme app extension. Merchants: treat any app that still relies on script tags as a risk for 1 March 2027.

Thank you page upgrade deadline for stores not on Plus
Who it affects: Merchants
The last day for stores not on Shopify Plus to upgrade their Thank you and Order status pages. Shopify upgraded stores that hadn’t done it themselves, and apps, scripts or pixels that don’t work on the new pages have to be replaced.
What to do
Place a test order and check your conversion tracking still fires. Rebuild missing tracking as a web pixel, and missing page content with an app block or UI extension.

Shopify Scripts stop running
Who it affects: Shopify Plus merchants
Shopify Scripts are deprecated, and any still published are switched off. Line item, shipping and payment scripts no longer change anything at checkout.
What to do
If discounts, shipping rates or payment methods changed at checkout after this date, check whether a script used to handle them, and rebuild that logic with Shopify Functions.

Shopify Scripts can no longer be edited
Who it affects: Shopify Plus merchants
Plus stores can no longer edit or publish Shopify Scripts. Scripts already published keep running until 30 June 2026.
What to do
Use Shopify’s Scripts customisations report to see what each script does, then rebuild it with Shopify Functions or a public app.

Plus Thank you and Order status pages lose checkout.liquid
Who it affects: Shopify Plus merchants
On Shopify Plus, checkout.liquid, additional scripts and app script tags stop working on the Thank you and Order status pages.
What to do
Rebuild tracking on those pages as web pixels, and page content as checkout and customer account UI extensions.

checkout.liquid stops working in checkout
Who it affects: Shopify Plus merchants
Shopify Plus stores can no longer customise the Information, Shipping and Payment pages with checkout.liquid. Checkouts that haven’t upgraded are moved to Shopify’s standard checkout without their customisations.
What to do
Rebuild checkout customisations with Checkout Extensibility: checkout UI extensions, Shopify Functions and web pixels.

How to use the calendar
- Start with the soonest date. Each deadline says who it affects: merchants, Shopify Plus merchants or app developers. If it’s yours, the “what to do” box says where to start.
- Subscribe to the feed. Add the calendar to Apple Calendar, Outlook or Google Calendar and new deadlines appear on their own, each with what to do and a link to Shopify’s source. There’s no sign-up and no email address to give.
- Send the list to your app vendors. Most of these dates land on apps rather than your theme. Send each vendor the deadlines that apply and ask for a written answer. If one can’t meet a date, we can build what you need as a custom Shopify app.
- Read the background. Our round-up of Shopify Editions Fall ’26 for UK brands covers the developer deadlines alongside the rest of the release.
How we keep it up to date
- Shopify’s own sources only. Every date comes from shopify.dev, Shopify’s help centre or the Shopify changelog, and links to it. If Shopify has announced a change without a date, it isn’t listed until it has one.
- Checked by hand. Each deadline shows when we last checked it against its source. Shopify does move dates: it extended the end of Shopify Scripts to 30 June 2026.
- Rebuilt every day. The page and the feed are rebuilt every day, so the days left count down and passed deadlines move to the archive. The date above the list shows the day the count is from. We keep passed deadlines in the archive rather than delete them.
- Missing a date? If you know of a dated Shopify change that isn’t here, tell us about it and we’ll check it against Shopify’s sources.
Questions
Frequently asked questions
How often is the calendar updated?
The page and the calendar feed are rebuilt every day. The days left are counted from the date shown above the list. We add or change a deadline by hand when Shopify announces or moves a date, and each one shows when we last checked it.
Do I need to give you an email address to subscribe?
No. The feed is a public file that your calendar app fetches like any web page. There is no sign-up, and nothing in the feed tracks you.
Why isn't a date I've heard about on the list?
We only list dates we can find on Shopify's own pages, on shopify.dev, in the help centre or in the changelog. A change Shopify has announced without a date waits until it has one. If you know of a dated change we've missed, tell us through our contact page.
Does every deadline affect my store?
No. Most only matter if an app or customisation still works the old way. Script tags, for example, only matter if an app still loads code into your storefront that way. The quickest check is to ask each app vendor in writing, or to ask us for a theme and app audit.
Can I get a reminder before a deadline?
Yes, through your calendar app. Subscribe to the feed, then set an alert for all-day events in your calendar app's settings, such as a week before. The feed carries no alerts of its own, so it won't override yours.
Get a theme and app audit before the next deadline
Most of these dates break things quietly: a widget stops loading, tracking stops firing or an app loses access to your data. We’ll check every app and integration on your store against the dates above and fix what’s at risk. Talk to us about a theme and app audit, or compare our Shopify retainers if you’d rather someone kept an eye on these dates for you.
