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

Starting October 1, 2026, the scriptTagCreate and scriptTagUpdate mutations will return an user error, and the ScriptTag REST Admin API resource will reject POST and PUT . The deprecation applies to all API versions, including older ones, so pinning won’t defer it. On March 1, 2027, Shopify will stop injecting script tags into storefronts.
