# CloudKit.Response

The [`CloudKit.Response`](/documentation/CloudKitJS/CloudKit.Response) class is an abstract superclass for subclasses that encapsulate the response from server requests. Don’t create instances of this class. Instances of subclasses are returned by methods in the [`CloudKit.Container`](/documentation/CloudKitJS/CloudKit.Container) and [`CloudKit.Database`](/documentation/CloudKitJS/CloudKit.Database) classes. Most of these methods return a `Promise` object that resolves to a subclass of [`CloudKit.Response`](/documentation/CloudKitJS/CloudKit.Response) if the operation is successful.

```
interface CloudKit.Response
```

## Overview

For examples of methods that resolve to a [`CloudKit.Response`](/documentation/CloudKitJS/CloudKit.Response) subclass, read [`CloudKit.Database`](/documentation/CloudKitJS/CloudKit.Database).

## Topics
