Slack Integration
Configure Slack notifications to keep your team informed about feature flag activity, stale alerts, and cleanup PRs.
4 min readLast updated: May 22, 2026
The Slack integration sends notifications to your team's Slack channels via incoming webhooks. Stay informed about flag detection, stale flag alerts, and automated cleanup PRs without leaving Slack.
The Slack integration requires a Team plan or higher.
Features
| Notification Type | Description | Controlled by |
|---|---|---|

| Stale Flag Alerts | When flags exceed the stale threshold (daily schedule) | Stale Flag Alerts toggle |
| Cleanup PR Created | When FlagShark creates a cleanup PR | Stale Flag Alerts toggle |
Setting Up Slack

Configuration Options
| Setting | Description | Default |
|---|---|---|
| Enabled | Master toggle for all Slack notifications | Off |
| Webhook URL | Your Slack incoming webhook URL | Required |
| Channel | Target Slack channel (for display only) | #flagshark |
| Stale Flag Alerts | Send alerts when flags become stale, and when cleanup PRs are created | On |
PR flag notifications are always on when Slack is enabled. When FlagShark detects flags added or removed in a pull request, it always posts to Slack — this fires for every PR event regardless of the Stale Flag Alerts setting.
