## Response

A successful deletion returns HTTP status `204 No Content` with an empty body. Success is indicated by the status code, not the body.

## Response example

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

## Error response example

404 — no unit of measure with this `id` exists, for example when the same unit is deleted twice:

```json
{
  "success": false,
  "error": {
    "code": "ENTITY_NOT_FOUND",
    "message": "measure does not exist."
  }
}
```

## Errors

| HTTP | Code | Description |
|------|-----|---------|
| 404 | `ENTITY_NOT_FOUND` | No unit of measure with this `id` exists on the Bitrix24 account, including one already deleted |
| 400 | `INVALID_PARAMS` | `id` is not a non-negative integer, for example `abc`. The request is rejected before execution, and no data on the Bitrix24 account changes |
| 403 | `SCOPE_DENIED` | The API key does not have the `catalog` scope |
| 401 | `TOKEN_MISSING` | The API key has no configured tokens |
| 401 | `MISSING_API_KEY` | The `X-Api-Key` header is missing |
