# 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 Slack [incoming webhooks](https://docs.slack.dev/messaging/sending-messages-using-incoming-webhooks/) 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, set up your incoming webhook. For help, see the [Slack documentation](https://docs.slack.dev/messaging/sending-messages-using-incoming-webhooks/).

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