Sending notifications to Slack

cside supports a Slack-specific webhook format that delivers pre-formatted notifications directly to your Slack channels. Alerts appear as rich messages with all relevant threat details.

Prerequisites

Before you begin, you’ll need a Slack incoming webhook URL:

1. Go to your Slack workspace
2. Navigate to Apps → Incoming Webhooks
3. Click Add to Slack
4. Select the channel where you want to receive notifications
5. Copy the webhook URL provided

Setting up a Slack webhook destination

1. Open the dashboard and navigate to Team Settings > Notifications
2. Create a new notification config or edit an existing one
3. Under Send To, click Add destination and select Webhook
4. In the Configuration panel:
   • URL: paste your Slack webhook URL (e.g., https://hooks.slack.com/services/YOUR/WEBHOOK/URL)
   • Secret: enter a secret key for HMAC signature verification
   • Format: select Slack
5. Click Save or Save & Test

Once saved, cside automatically formats notifications for Slack and sends them to your specified channel whenever the configured trigger fires.
