## Get a chat folder

`GET /v1/chats/folders/:folderId`

Returns one of the current user's folders. For a personal folder, it also returns the folder's chats and the users of the direct dialogs it contains.

The chats of a system folder are returned by [`GET /v1/chats/folders/:folderId/recent`](/docs/chats/discovery/folder-recent).

## Parameters

| Parameter | Type | Required | Description |
|----------|-----|:-----:|---------|
| `folderId` (path) | number | yes | Folder ID — the `id` field in [`GET /v1/chats/folders`](/docs/chats/discovery/folders). A positive integer |

The endpoint takes no query parameters: any query parameter is rejected with `400 INVALID_PARAMS`.

## Response example

A personal folder with one group chat:

    "chats": [
      {

        "entityData2": "",
        "entityData3": "",
        "entityId": "",
        "entityType": "",
        "extranet": false,
        "containsCollaber": false,
        "id": 5287,
        "parentChatId": 0,
        "parentMessageId": 0,

A system folder — the lists are empty:

```json
{
  "success": true,
  "data": {

    "users": [],
    "folder": {
      "id": 27,

      "displaysNestedInRoot": false,
      "definition": { "recentSection": "default", "parentChatId": 0 }
    }
  }
}
```

## Error response example

422 — no folder with this `folderId`:

```json
{
  "success": false,
  "error": {
    "code": "BITRIX_ERROR",
    "message": "FOLDER_NOT_FOUND",
    "b24Code": "FOLDER_NOT_FOUND"
  }
}
```

## Errors

| HTTP | Code | Description |
|------|-----|---------|
| 400 | `INVALID_PARAMS` | `folderId` is not a positive integer, or a query parameter was passed. Checked before any call to Bitrix24 |
| 422 | `BITRIX_ERROR` | Bitrix24 returned an error; the portal code is in `error.b24Code`: `FOLDER_NOT_FOUND` — no such folder, `FOLDER_ACCESS_DENIED` — another user's folder |
| 404 | `ENTITY_NOT_FOUND` | Bitrix24 answered "not found"; the portal code is in `error.b24Code` |
| 403 | `SCOPE_DENIED` | The API key does not have the `im` scope |
| 401 | `TOKEN_MISSING` | The API key has no Bitrix24 tokens configured |
| 502 | `BITRIX_UNAVAILABLE` | Bitrix24 is unavailable or returned a server error |

Full list of common API errors — [Errors](/docs/errors).

## Known specifics

- **A read-only key can make the call.** The call's argument is a folder, not a chat, so reading a folder does not make the user a member of its chats and does not count as a write. The folder list [`GET /v1/chats/folders`](/docs/chats/discovery/folders) returns `403 WRITE_BLOCKED_READONLY_KEY` to such a key, so get the `folderId` with a key that has write access.
- **`FOLDER_NOT_FOUND` arrives in `error.b24Code` of a `422 BITRIX_ERROR` response.** Do not confuse it with the `404 FOLDER_NOT_FOUND` on [Upload a file to a chat](/docs/chats/files/upload).
