Extension

Meta information about an extension target.

• apiVersion

  The API version that was set in the extension config file.

  ApiVersion

• capabilities

  The allowed capabilities of the extension, defined in your [shopify.ui.extension.toml](/docs/api/checkout-ui-extensions/configuration) file. * [`api_access`](/docs/api/checkout-ui-extensions/configuration#api-access): the extension can access the Storefront API. * [`network_access`](/docs/api/checkout-ui-extensions/configuration#network-access): the extension can make external network calls. * [`block_progress`](/docs/api/checkout-ui-extensions/configuration#block-progress): the extension can block a buyer's progress and the merchant has allowed this blocking behavior.

  StatefulRemoteSubscribable<Capability[]>

• editor

  Information about the editor where the extension is being rendered. The value is undefined if the extension is not rendering in an editor.

  Editor

• rendered

  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 buyer has navigated away from where it was rendered. The extension continues running so that your extension is immediately available to render if the buyer 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.

  Target

• version

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 For unpublished extensions, the value is `undefined`.
