# Notification Channels

> Org-level alerting configuration that routes policy violations and other governance events to Slack, Teams, email, PagerDuty, or a custom webhook.

Notification Channels are configured at the organization level (under Organization Settings) and apply across every project, so your team gets alerted on governance events without watching the [Audit Log](/observability/audit-log) directly.

## Channel types

* **Email**
* **Slack**
* **Microsoft Teams**
* **PagerDuty**
* **Custom webhook**

## Fields

* **Name**
* **Channel type**
* **Recipients** (for email channels)
* **Severity filter** — `high`, `medium`, `low`
* **Action filter** — which event types trigger the channel (e.g. `policy_violation`)
* **Enabled** toggle

## Payload signing

Custom webhook channels receive the same signed-payload pattern as [Webhooks](/governance/webhooks):

```
X-Gegentic-Event: policy_violation
X-Gegentic-Signature: sha256=<hmac>
```

## Testing a channel

Each channel has a **Test** action that sends a sample notification, so you can confirm delivery before relying on it in production.
