## Create a knowledge base

`POST /v1/note/collections`

Creates a knowledge base — a container for documents in Bitrix24 Knowledge Base 2.0. The body is passed flat, without a `fields` wrapper.

## Request fields (body)

| Field | Type | Required | Description |
|------|-----|:-----:|---------|
| `name` | string | yes | Knowledge base name |
| `position` | integer | no | Position in the list. Sorted by descending value. Defaults to `0` — the knowledge base is placed at the top of the list |
