# Slack

The Slack output plugin delivers records or messages to your preferred Slack channel. It formats the outgoing content in JSON format for readability.

This connector uses the Slack *Incoming Webhooks* feature to post messages to Slack channels. Using this plugin in conjunction with the Stream Processor is a good combination for alerting.

## Slack Webhook

Before configuring this plugin, make sure to setup your Incoming Webhook. For detailed step-by-step instructions, review the following official documentation:

* <https://api.slack.com/messaging/webhooks#getting_started>

Once you have obtained the Webhook address you can place it in the configuration below.
