## Update folder

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

Changes the name, symbolic code, parent folder or home page of a folder. Pass only the fields you change.

## Parameters

| Parameter | Type | Required | Description |
|----------|-----|:-----:|---------|
| `id` (path) | number | yes | Site identifier — a positive integer. List: [`GET /v1/sites`](/docs/entities/sites/list) |
| `folderId` (path) | number | yes | Identifier of a folder on this site. List: [`GET /v1/sites/:id/folders`](/docs/entities/sites/folders/list) |
| `scope` (query) | string | no | Internal landing scope: `KNOWLEDGE` / `GROUP` / `MAINPAGE`. Specify it if the site belongs to the corresponding scope. Otherwise `404 ENTITY_NOT_FOUND` is returned |

## Request fields (body)

| Field | Type | Required | Description |
|------|-----|:-----:|---------|
| `title` | string | no | New folder name, a non-empty string |

| `parentId` | number \| null | no | Identifier of the new parent folder on this site. List: [`GET /v1/sites/:id/folders`](/docs/entities/sites/folders/list). `null` moves the folder to the site root. If the field is omitted, the folder keeps its current parent |

## Errors

| HTTP | Code | Description |
|------|-----|---------|
| 400 | `MISSING_REQUIRED_FIELDS` | The request body is empty or not an object |
| 400 | `READONLY_FIELD` | The body contains a read-only field: `id`, `siteId`, `active`, `deleted`, `createdById`, `modifiedById`, `dateCreate`, `dateModify` |
| 400 | `INVALID_PARAMS` | The body contains a field other than `title`, `code`, `parentId`, `indexPageId` |
| 400 | `INVALID_PARAMS` | `title` is empty, `title` or `code` is not a string, `parentId` or `indexPageId` is neither a positive integer nor `null` |
| 400 | `INVALID_PARAMS` | `id` or `folderId` is not a positive integer |
| 400 | `INVALID_SCOPE` | `scope` is not `KNOWLEDGE`, `GROUP` or `MAINPAGE` |
| 404 | `ENTITY_NOT_FOUND` | No site with this `id`, the site is not accessible to the key's user, or it belongs to a different `scope` |
| 404 | `ENTITY_NOT_FOUND` | No folder with this `folderId` on this site, or it is not accessible |
| 404 | `ENTITY_NOT_FOUND` | The `parentId` folder does not exist on this site or is not accessible |
| 404 | `ENTITY_NOT_FOUND` | The folder was not found after the operation: a concurrent request moved or deleted it |
| 422 | `BITRIX_ERROR` | Bitrix24 rejected the change, for example `indexPageId` points to a missing page or a page of another site. The reason is in `message` |
| 409 | `LANDING_MODULE_NOT_ENABLED` | The Sites module is unavailable on this Bitrix24 account. Ask a Bitrix24 account administrator to enable it — until then a retry returns the same refusal |
| 403 | `BITRIX_ACCESS_DENIED` | Bitrix24 denied access: the key's user is not an administrator, or the feature is unavailable on the Bitrix24 account |
| 403 | `WRITE_BLOCKED_READONLY_KEY` | The API key is read-only |
| 403 | `SCOPE_DENIED` | The API key does not have the `landing` scope |
| 401 | `TOKEN_MISSING` | The API key has no configured tokens |
| 401 | `MISSING_API_KEY` | The `X-Api-Key` header is missing |

## Known specifics

- **Assigning a home page does not move the page into the folder.** After `indexPageId` is set, the page's `folderId` in [`GET /v1/pages/:id`](/docs/entities/pages/get) stays the same.
