How to Connect Slack (via Webhooks)
Send Nova alerts, incident updates, and AI-generated summaries directly to your Slack channels using incoming webhooks. This guide walks you through setting up the Slack integration.
Steps
Create a Slack Incoming Webhook
In Slack, go to Apps > Incoming Webhooks (or visit api.slack.com/apps). Create a new app, enable Incoming Webhooks, and add a webhook to your desired channel.
Copy the webhook URL
Slack gives you a URL like:
Add the webhook to Nova
Go to Settings > Integrations > Slack in Nova. Click Add Webhook, paste the URL, and give it a friendly name (e.g., "#incidents-channel").
Configure notification types
Choose which events should be sent to this Slack channel:
- Alert triggers — new alerts matching your severity filter
- Incident updates — status changes, acknowledgements, resolutions
- AI summaries — daily or weekly digests of system health
- Deployment markers — notifications when new code is deployed
Test the connection
Click Send Test Message. A sample alert should appear in your Slack channel within seconds.
Create separate webhooks for different channels: #alerts for all alerts, #incidents for active incidents, and #deploys for deployment notifications. This keeps each channel focused.
Route alerts to specific channels
When creating or editing alert rules, select which Slack webhook to use in the notification settings. You can route critical alerts to #oncall and warnings to #monitoring.
