# Slack

## Overview

The Slack StackPack allows you to receive event notifications in Slack channels. The StackPack installs a number of event handler functions that can be used when [adding an event handler](/5.1/use/events/manage-event-handlers.md#add-event-handler) to a view in StackState.

Slack is a [StackState core integration](/5.1/stackpacks/integrations/about_integrations.md#stackstate-core-integrations).

* Event handlers added to a StackState view run an event handler function in response to events that are generated in StackState.
* A Slack event handler function sends an alert to the specified Slack Webhook URL with details of the generated event.
* An alert appears in the Slack channel associated with the specified Slack Webhook.
