## Create an Alert

In your Application, go to the **Settings** tab and find the **Alerting** section. Click **Create Alert**.

| Field           | Description                                  |
| --------------- | -------------------------------------------- |
| **Name**        | A slug-friendly name like `expiry-alert`     |
| **Alert Type**  | Expiration, Issuance, Renewal, or Revocation |
| **Description** | Optional context about this alert            |

For expiration alerts, you'll also configure:

| Field            | Description                                                                   |
| ---------------- | ----------------------------------------------------------------------------- |
| **Alert Before** | How far before expiration to notify (e.g., `30d`, `2w`, `1m`)                 |
| **Daily Alerts** | If enabled, sends daily reminders until the certificate expires or is renewed |

## Notification Channels

Add one or more channels to receive alerts (up to 10 per alert):

| **[Slack](/documentation/platform/pki/applications/alerting/slack)**         | Post to a Slack channel via Incoming Webhook                    |

## FAQ

<AccordionGroup>
  <Accordion title="Do alerts apply to all certificates in the Application?">
    Yes. When you create an alert on an Application, it monitors all certificates issued within that Application. The Application itself is the scope.
  </Accordion>

  <Accordion title="When do expiration alerts run?">
    Expiration alerts are checked on a daily schedule. Event-driven alerts (Issuance, Renewal, Revocation) fire in real-time.
  </Accordion>

  <Accordion title="Can I have multiple alerts on one Application?">
    Yes. You can create multiple alerts with different types and notification channels. For example, an expiration alert to Slack and an issuance alert to a webhook for audit logging.
  </Accordion>
