# event_not_found

**No event with this external_id in this calendar.**

| | |
|---|---|
| HTTP status | `404` |
| `code` | `event_not_found` |
| Retry? | No, fix the request first |

## What it means

Only happens when reading a single event. `DELETE` answers `204` for events that do not exist, too.

## How to fix it

Check the `external_id` (case matters) and the calendar. Use `PUT` to create the event.

## Example

```json
{
  "type": "https://docs.kalender-sync.de/en/api/errors/event_not_found",
  "title": "Not found",
  "status": 404,
  "code": "event_not_found",
  "detail": "No event with this external_id in this calendar.",
  "request_id": "req_…"
}
```
