## Delete event

`DELETE /v1/calendar-events/:id`

Deletes a calendar event by identifier. A deleted event cannot be restored via the API — create a new one if needed.

## Parameters

| Parameter | Type | Req. | Description |
|----------|-----|:-----:|---------|
| `id` (path) | number | yes | Event ID |

## Examples

### curl — personal key

```bash
curl -X DELETE "https://vibecode.bitrix24.com/v1/calendar-events/7773" \
  -H "X-Api-Key: YOUR_API_KEY"
```

### curl — OAuth application

```bash
curl -X DELETE "https://vibecode.bitrix24.com/v1/calendar-events/7773" \
  -H "X-Api-Key: YOUR_APP_KEY" \
  -H "Authorization: Bearer USER_SESSION_TOKEN"
```

### JavaScript — personal key

```javascript
const res = await fetch('https://vibecode.bitrix24.com/v1/calendar-events/7773', {
  method: 'DELETE',
  headers: {
    'X-Api-Key': 'YOUR_API_KEY',
  },
})

if (res.status === 204) {
  console.log('Event deleted')
}
```

### JavaScript — OAuth application

```javascript
const res = await fetch('https://vibecode.bitrix24.com/v1/calendar-events/7773', {
  method: 'DELETE',
  headers: {
    'X-Api-Key': 'YOUR_APP_KEY',
    'Authorization': 'Bearer USER_SESSION_TOKEN',
  },
})

if (res.status === 204) {
  console.log('Deleted')
}
```

## Response

On successful deletion, an HTTP status `204 No Content` is returned with an empty body. The success indicator is the response code, not the content.

## Response example

```
HTTP/1.1 204 No Content
```

## Error response example

422 — the event was already deleted or never existed:

```json
{
  "success": false,
  "error": {
    "code": "BITRIX_ERROR",
    "message": "An error occurred while deleting the event"
  }
}
```

## Errors

| HTTP | Code | Description |
|------|-----|---------|
| 422 | `BITRIX_ERROR` | The event with the specified `id` does not exist or is already deleted |
| 403 | `SCOPE_DENIED` | The API key does not have the `calendar` scope |
| 401 | `TOKEN_MISSING` | The API key has no configured tokens |

## Known specifics

**Recurring events.** Deleting an event with a recurrence rule (`rrule`) removes the entire series — all occurrences with the same `parentId`. A single occurrence cannot be removed from a series via the API.
