## Child nodes

`GET /v1/humanresources/nodes/:id/children`

Returns the direct child nodes of the specified organizational structure node — departments and teams one level below in the tree. Nesting deeper than the first level is not expanded.

## Parameters

| Parameter | Type | Required | Description |
|----------|-----|:-----:|---------|
| `id` (path) | number | yes | Parent node identifier. List nodes: `GET /v1/humanresources/nodes?type=DEPARTMENT` |

| `data.items[].id` | number | Node identifier |
| `data.items[].name` | string | Node name |
| `data.items[].type` | string | Node type: `DEPARTMENT` or `TEAM` |
| `data.items[].structureId` | number | Identifier of the structure the node belongs to |
| `data.items[].parentId` | number | Parent node identifier — matches `:id` in the request |
| `data.items[].description` | string \| null | Node description. `null` if no description is set |

| `data.items[].colorName` | string \| null | Node color name. `null` if no color is set |
| `data.items[].xmlId` | string \| null | External node identifier. `null` if not set |
| `data.items[].createdAt` | string \| null | Creation date (ISO 8601). `null` for nodes created without a timestamp |
| `data.items[].updatedAt` | string \| null | Last modification date (ISO 8601). `null` if there were no changes |

## Response example

```json
{
  "success": true,
  "data": {
    "items": [
      {
        "id": 23,
        "name": "Sales department",
        "type": "DEPARTMENT",
        "structureId": 1,
        "parentId": 17,
        "description": "Direct sales",
        "accessCode": "SN23",
        "userCount": 2,
        "colorName": null,
        "xmlId": null,
        "createdAt": null,
        "updatedAt": null
      }
    ]
  }
}
```

## Error response example

400 — `:id` is not a positive integer:

```json
{
  "success": false,
  "error": {
    "code": "INVALID_PARAMS",
    "message": "id must be a positive integer"
  }
}
```

## Errors

| HTTP | Code | Description |
|------|-----|---------|
| 400 | `INVALID_PARAMS` | `:id` is not a positive integer (`0`, negative, or a non-numeric value) |
| 403 | `SCOPE_DENIED` | The key is missing the `humanresources` scope |
| 401 | `TOKEN_MISSING` | The API key has no Bitrix24 tokens configured |

## Known specifics

**The node array is nested under `data.items`.** Unlike the [node list](/docs/humanresources/nodes/list), where records sit in a flat `data`, child nodes are located under `data.items`.

**Only direct descendants are returned.** The response contains nodes exactly one level below the parent. To build the full subtree, call the endpoint recursively for each node in `data.items` that has its own descendants.
