 `'Sentry-Hook-Resource': 'event_alert'`
 
+## Issue Types
+
+The `event_alert.triggered` webhook fires for multiple issue types, not just traditional errors. The payload structure varies depending on what kind of issue triggered the alert. You can identify the issue type by checking for the `occurrence` field in `data.event` — it's absent for error events and present for all other issue types.
+
+| Issue Type      | `occurrence` field | `occurrence.type` | Key Fields                                                |
+| --------------- | ------------------ | ----------------- | --------------------------------------------------------- |
+| Error/Exception | absent             | —                 | `exception`, `stacktrace`, `request`, `user`              |
+| Cron Monitor    | present            | `4001`            | `contexts.monitor`, `monitor.*` tags                      |
+| Uptime Monitor  | present            | `7001`            | `evidenceDisplay` (failure reason, duration, status code) |
+| Metric Issue    | present            | `8001`            | `evidenceData.alert_id`                                   |
+
+<Alert>
+
+Metric issues here refer to issues created when a metric alert rule triggers an issue alert — this is distinct from the [`metric_alert` resource webhook](/integrations/integration-platform/webhooks/metric-alerts/), which has its own payload format.
