## Delete item

`DELETE /v1/items/:entityTypeId/:id`

Deletes a smart process item by ID. A deleted item cannot be restored through the API — create a new one if needed.

## Parameters

| Parameter | Type | Required | Description |
|----------|-----|:-----:|---------|
| `entityTypeId` (path) | number | yes | Smart process type ID. Retrieve: [GET /v1/smart-processes](/docs/entities/smart-processes/list). Reserved values (`1`, `2`, `3`, `4`, `7`, `31`) are served by specialized APIs: `/v1/leads`, `/v1/deals`, `/v1/contacts`, `/v1/companies`, `/v1/quotes`, `/v1/invoices` |
| `id` (path) | number | yes | Item ID |

## Examples

In the examples `entityTypeId = 177`, `id = 783` — replace with your values.

    'X-Api-Key': 'YOUR_APP_KEY',
    'Authorization': 'Bearer USER_SESSION_TOKEN',
  },
})

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

## Response

On successful deletion the HTTP status `204 No Content` is returned with an empty body — success is determined by the status.

## Response example

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

## Error response example

400 — reserved `entityTypeId` (for standard CRM entities):

```json
{
  "success": false,
  "error": {
    "code": "INVALID_DYNAMIC_PARAM",
    "message": "entityTypeId 2 has a dedicated API: use /v1/deals instead"
  }
}
```

## Errors

| HTTP | Code | Description |
|------|-----|---------|
| 400 | `INVALID_DYNAMIC_PARAM` | `entityTypeId` is not a positive integer or is reserved (1, 2, 3, 4, 7, 31) |
| 404 | `ENTITY_NOT_FOUND` | No item found with the specified ID |
| 403 | `SCOPE_DENIED` | The API key does not have the `crm` scope |
| 401 | `TOKEN_MISSING` | The API key has no configured tokens |
