Migrate to Polaris

Version 2025-07 is the last API version to support React-based UI components. Later versions use web components, native UI elements with built-in accessibility, better performance, and consistent styling with Shopify's design system. Check out the migration guide to upgrade your extension.

Editor
```
rendered
A Boolean to show whether your extension is currently rendered to the screen. Shopify might render your extension before it's visible in the UI, typically to pre-render extensions that will appear on a later step of the checkout. Your extension might also continue to run after the customer has navigated away from where it was rendered. The extension continues running so that your extension is immediately available to render if the customer navigates back.
```
StatefulRemoteSubscribable<boolean>
```
scriptUrl
The URL to the script that started the extension target.
```
string
```
target
The identifier that specifies where in Shopify’s UI your code is being injected. This will be one of the targets you have included in your extension’s configuration file.
```

```
version
The published version of the running extension target. For unpublished extensions, the value is `undefined`.
```
string
```

ApiVersion

The supported GraphQL Admin API versions. Use this to specify which API version your GraphQL queries should execute against. Each version includes specific features, bug fixes, and breaking changes. The `unstable` version provides access to the latest features, and can change without notice because it's not subject to versioning guarantees.
