Theme app extensions

Your app might not pass App Store review if it uses script tags instead of theme app extensions. All new apps, and apps that integrate with Online Store 2.0 themes, should use theme app extensions, such as app blocks or app embed blocks. Script tags are an alternative you can use with only vintage themes. Learn more.

The ScriptTag resource represents remote JavaScript code that is loaded into the pages of a shop's storefront or the order status page of checkout. This lets you add functionality to those pages without using theme templates.

Script tags are scoped to the app that created them. When an app is uninstalled from a shop, all of the script tags that it created are automatically removed along with it.
