 # Audit Logs API Client
 
-[Audit Logs API](https://api.slack.com/admins/audit-logs) is a set of
-APIs for monitoring what's happening in your [Enterprise
-Grid](https://api.slack.com/enterprise/grid) organization.
-
-The Audit Logs API can be used by security information and event
-management (SIEM) tools to provide an analysis of how your Slack
-organization is being accessed. You can also use this API to write your
-own applications to see how members of your organization are using
-Slack.

-Follow the instructions in [the API

-for using Audit Logs API. The Slack app using the Audit Logs API needs
-to be installed in the Enterprise Grid Organization, not an individual
-workspace within the organization.
