POS UI extensions now support reactive storage access
Shopify developer change
MerchantDiff detected this entry in Shopify's official developer changelog on October 22, 2026.
This Shopify update is categorized as API, New, POS Extensions, 2026-10.
What changed
shopify.storage.current exposes each storage key as a read-only reactive signal. You can read its current value or subscribe to changes made by other targets of the same extension on the same POS device. Writes and removals still use the existing Storage API methods. For example, a background target can fetch and store a customer’s loyalty points, and a smart grid tile can react to those changes automatically. This keeps the displayed balance up to date without repeated storage reads or custom polling logic.
Who is affected
This addition is available to POS UI extensions that use API version 2026-10 or later. Extensions that use earlier API versions can’t use shopify.storage.current.
What action may be needed
You don’t need to take action. Existing Storage API methods continue to work as before. To adopt reactive storage, update your extension to use API version 2026-10 or later and read or subscribe to the keys your extension needs through shopify.storage.current.
