# App

The App API provides information about the app and the status of its extensions.

Tip

At this time, the App API only supports returning the activations on checkout and customer account UI extensions.

## Extensions method

The `app.extensions()` method asynchronously retrieves detailed information about the app's checkout and customer account extensions, including which targets they are activated on.

It returns a Promise that resolves to an array of `ExtensionInfo` objects. Each object contains the extension's handle and its activation targets. The array may be empty if the app has no extensions.

* activations

  ExtensionActivation\[]

  required

  List of activation records for the extension. Contains information about where the extension is currently activated.

* handle

  string

  required

  The unique identifier for the extension.

### ExtensionActivation

Represents an activation record for an extension. Contains information about where an extension is activated.

* target

  The target identifier for the extension activation.

  ```ts
  string
  ```

```ts
export interface ExtensionActivation {
  /**
   * The target identifier for the extension activation.
   */
  target: string;
}
```
