## Add members

`POST /v1/humanresources/nodes/:id/members/add`

Adds one or more employees to an organizational structure node with the specified role. A single call can add several members at once — all of them receive the same role.

## Parameters

| Parameter | Type | Required | Description |
|----------|-----|:-----:|---------|
| `id` (path) | number | yes | Identifier of the node members are added to. List of identifiers: `GET /v1/humanresources/nodes?type=DEPARTMENT` |

## Request body fields

| Field | Type | Required | Description |
|------|-----|:-----:|---------|
| `userIds` | array | yes | Employee identifiers. Search: `POST /v1/humanresources/employees/search` |
| `role` | string | yes | Role assigned to all added employees. The set of roles depends on the node type. Available roles — [Node members](/docs/humanresources/members) |

    "message": "Request object validation failed",
    "validation": [
      {
        "field": "MISSING_ROLE",
        "message": "Parameter \"role\" is required."
      }
    ]
  }
}
```

## Errors

| HTTP | Code | Description |
|------|-----|---------|
| 400 | `INVALID_PARAMS` | The `role` parameter was not provided (`validation[].field` = `MISSING_ROLE`) |
| 400 | `INVALID_PARAMS` | Invalid `role` value for the node type. The message lists the allowed roles (`validation[].field` = `INVALID_ROLE`) |
| 400 | `INVALID_PARAMS` | Non-numeric `id` in the path — `id must be a positive integer` |
| 404 | `NOT_FOUND` | Unknown verb in the path after `members/`. The message lists the allowed ones: `move`, `remove`, `add`, `set` |
| 403 | `SCOPE_DENIED` | The key is missing the `humanresources` scope |
| 401 | `TOKEN_MISSING` | The API key has no Bitrix24 tokens configured |

## Known specifics

**The list of roles arrives in the error message.** When the role is invalid for the node type (`validation[].field` = `INVALID_ROLE`), the message lists the allowed values — you can pick a correct role from this list without consulting the reference.
