# ExtensionAbilityInfo

The **ExtensionAbilityInfo** module defines the ExtensionAbility information. A third-party application can obtain its own ExtensionAbility information through [bundleManager.getBundleInfoForSelf](js-apis-bundleManager.md#bundlemanagergetbundleinfoforself), with **GET_BUNDLE_INFO_WITH_HAP_MODULE** and **GET_BUNDLE_INFO_WITH_EXTENSION_ABILITY** passed in to [bundleFlags](js-apis-bundleManager.md#bundleflag).

> **NOTE**
>
> The initial APIs of this module are supported since API version 9. Newly added APIs will be marked with a superscript to indicate their earliest API version.
