A Google Apps Admin Audit API is now available. With this API administrators can survey the activities of all of the account’s administrators in the control panel. The API gives details about changes to a key subset of their Google Apps services and features settings including settings for Calendar, Chat, their delegated administrators, Docs, domain configuration, Gmail, Groups, mobile settings, organization hierarchy, Sites, and user settings. In addition to the setting changes, the API returns specifics about the change activity itself, including the IP address used by the administrator.
