DESCRIPTION:Requests to create or update a script tag return an error. Scri
 pt tags already on a store keep loading until 1 March 2027.\n\nWhat 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

DESCRIPTION:Shopify serves version 2025-10 of its APIs until 15:00 UTC on t
 his date. After that\, a request for it is answered by the oldest supporte
 d version instead\, which can change what an app gets back.\n\nWhat to do:

 on and test them before this date. If your store has a custom app\, ask wh

SUMMARY:Shopify: Bulk operations need an IP allowlist
DESCRIPTION: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 merchant
 s create themselves are not affected.\n\nWhat to do: App developers: add y
 our 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

SUMMARY:Shopify: Public apps without an IP allowlist are delisted
DESCRIPTION:All public apps need an IP allowlist\, not only those that run 
 bulk operations. From this date\, public apps without one are delisted fro
 m the Shopify App Store and blocked from new installs.\n\nWhat to do: App 
 developers: set the allowlist before this date. Merchants: if an app you u
 se disappears from the App Store\, ask its vendor why before you renew or 
 build on it.\n\nWho it affects: App developers\nShopify’s source: https:

SUMMARY:Shopify: Public apps must use expiring access tokens
DESCRIPTION:Public apps still on non-expiring offline access tokens are del
 isted 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.\n\nWhat to do: App developers: migrate to expiring offline 
 access tokens now\, because Shopify says the later dates are not extra tim
 e. Merchants: ask each public app’s vendor\, in writing\, whether they h
 ave migrated.\n\nWho it affects: App developers\nShopify’s source: https

SUMMARY:Shopify: The Knowledge Base app is retired
DESCRIPTION: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.\n\nWhat to do: If you used the app\, che
 ck your facts moved across. Stores with more than 1\,000 facts need to add

SUMMARY:Shopify: Admin warnings for apps on old tokens
DESCRIPTION:If you use a public app that still relies on non-expiring token
 s\, your Shopify admin shows a warning that the app’s service may be int
 errupted.\n\nWhat 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.\n\nWho it affects: Merchants\nShopify’s source: https://shop

SUMMARY:Shopify: Script tags stop loading on storefronts
DESCRIPTION:Shopify stops loading script tags on online store pages\, which
 ever API version an app uses. Anything an app still adds that way\, such a
 s reviews\, chat\, pop-ups or tracking\, stops working.\n\nWhat to do: Lis
 t every app that adds code to your storefront and ask each vendor whether 
 it has moved to an app embed block or a web pixel. After each move\, check
  the app embed is switched on in your live theme\, then remove the old scr
 ipt tag.\n\nWho it affects: Merchants and app developers\nShopify’s sour

SUMMARY:Shopify: Old app tokens stop working
DESCRIPTION:Admin API calls made with non-expiring offline access tokens re
 turn 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 no
 t affected.\n\nWhat to do: Replace any public app whose vendor hasn’t co
 nfirmed the move to expiring tokens. App developers: this is when calls st
 art failing\, not an extension of the 1 January 2027 deadline.\n\nWho it a
