# Update knowledge base (/api-reference/knowledge-bases/updateKnowledgeBase)

`PATCH /api/v2/knowledge/{knowledgeBaseId}`

## Description
Update a knowledge base's name, description, chunking configuration, or folder placement. Workspace folder trees exceeding 10,000 folders return `413`.

OAuth scope: `api:write`.

## Parameters

- **knowledgeBaseId** (path) (required) — `string`: Unique knowledge base identifier.

## Request Body

Workspace scope and fields to update. At least one mutable field is required.
