Shopify developer change
MerchantDiff detected this entry in Shopify's official developer changelog on October 12, 2026.
This Shopify update is categorized as API, New, POS Extensions, 2026-10.
What changed
shopify.extension.version returns the version of the extension that is running. It’s the same name shown on the Versions page in the Dev Dashboard and chosen when running shopify app deploy. The value is an opaque name, not a version number, so compare it for equality rather than sorting it. It’s undefined when the extension runs from a local development server.
Who is affected
This field is available to POS UI extensions that target API version 2026-10. Extensions targeting earlier API versions are unchanged.
What action may be needed
No action is required for existing extensions. To use the field, target API version 2026-10. Account for undefined when testing from a local development server.
