Script tags are deprecated and will stop running on March 1, 2027

Shopify Deprecates Script Tags for Storefronts

Shopify announces the deprecation of script tags, with a complete shutdown scheduled for March 1, 2027. Starting October 1, 2026, the scriptTagCreate and scriptTagUpdate GraphQL mutations will return user errors, and the ScriptTag REST Admin API resource will reject POST and PUT requests.

The deprecation affects all API versions, including legacy versions. Developers cannot defer this change by pinning to older API versions.

Impact on Shopify App Development

Script tags currently represent the last remaining injection point for apps on Shopify storefronts. Shopify previously removed script tag functionality from the Order status page, making storefronts the final location where this method still operates.

Apps that rely on script tags to load JavaScript on merchant storefronts need to migrate to alternative implementation methods before the March 2027 deadline. The six-month warning period between the API restriction (October 2026) and the complete shutdown (March 2027) provides a transition window for developers.

Migration Requirements

Developers must identify alternative approaches for loading storefront functionality. Shopify’s app extension framework and theme app extensions offer modern alternatives to script tag injection. Apps using script tags for analytics, widgets, or custom functionality need to evaluate these replacement options.

The universal application across all API versions means no technical workaround exists through version management. Development teams should audit their current script tag usage and begin migration planning to meet the October 2026 deadline for API changes.
