## Update folder

`PATCH /v1/sites/:id/folders/:folderId`

Omitted parentId preserves the current parent. Explicit parentId: null moves to root. Empty body is refused.

## Parameters

| Parameter | Type | Description |
|---|---|---|
| id | integer | Positive safe integer site ID |
| scope | string | Optional KNOWLEDGE / GROUP / MAINPAGE |
| folderId | integer | Positive safe integer folder ID belonging to the site |
| title | string | Non-empty title; required on create |
| code | string | URL segment |
| parentId | integer / null | Parent folder; null means root |
| indexPageId | integer / null | Index page of this site; null clears it |

Requires landing key scope. Pass scope for knowledge bases, groups and MAINPAGE. State fields are read-only. Dates are ISO 8601 wall clocks without an offset: Bitrix24 does not return the timezone.
