# Create Node

Create a knowledge-base node (folder or document) in the caller's org.

A `document` may carry inline `markdown` or reference an uploaded file via `source_file_id`; a `folder` is a structural container. `parent_id` must reference a live folder in the caller's organisation (root when null). `summary` is an optional free-text summary and `metadata` an optional caller-composed JSON object; both may be set on either type.
