# Create knowledge base import part URLs (/api-reference/knowledge-bases/createKnowledgeImportPartUrls)

`POST /api/v2/knowledge/imports/{importId}/parts`

## Description
Create signed URLs for multipart bundle upload parts. Requires the `uploading` state; other states return `409`.

OAuth scope: `api:write`.

## Parameters

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

- **workspaceId** (query) (required) — `string`: Workspace that owns the import.

- **upload-token** (header) (required) — `string`: Signed upload control token returned when the upload session was created.

## Request Body

Multipart part numbers for which signed URLs should be created.

### 400 — The request is invalid. This includes a query parameter sent with no value (`?limit=`, `?search=`), which is rejected rather than read as zero, empty, or the parameter default — omit the parameter instead.

### 403 — The caller lacks the rights this operation requires. When the cause is one a caller can act on, `error.details.code` names it. A resource in a workspace the caller cannot reach at all answers `404` instead, so absence and denial are indistinguishable.
