# Slack

Slack is the one destination we format specifically. When the webhook URL you provide is a Slack Incoming Webhook, we send Slack Block Kit rather than plain text, which turns the alert into a message with the site name linked directly to the finding in your account.

## Creating the webhook URL

1. Visit <https://api.slack.com/apps>
2. Click **Create New App**, choose **From scratch**, provide an **App Name** and pick your **Workspace**. Then click **Create App**.
3. In the new app, click **Incoming Webhooks**, switch the toggle to **On** and click **Add New Webhook**.
4. Select your **Workspace** and then **Channel for webhook**, then click **Allow**.
5. Copy the **Webhook URL**.

## Sending alerts to Slack

Open the **Config** modal on the watcher you want alerts from, enable **Send Webhook alerts**, and paste the URL into **Target webhook URI**.

Repeat per watcher. Each watcher carries its own webhook target, so different sites can go to different channels.

## Things to watch for

- Formatting is triggered by the URL, which must be a `https://hooks.slack.com/services/` Incoming Webhook. A Slack URL of any other kind is treated as a generic endpoint and receives plain JSON.
- The webhook URL is a secret. Anyone holding it can post to the channel, so treat it like a credential and rotate it in Slack if it leaks.
- A webhook posts to the channel chosen when it was created. To move alerts to a different channel, create a new webhook and update the watcher.

## Audit trail events

The Audit Trail webhook supports Slack too, formatted the same way. It is configured separately from Watch alerts - see [Audit Trail](/security-operations/audit-trail/).
