# Bulk import nodes and edges

`POST /api/v0/knowledge-graphs/{kg_id}/import`

Atomically creates a batch of nodes and edges. Each node may carry a ``ref`` string that edges in the same request can resolve as ``source_ref`` / ``target_ref``. The whole batch rolls back if any item fails validation.

## Path parameters

- `kg_id` string, uuid, required

## Request body

- BulkImportRequest
  - `nodes` BulkImportNode[]
    - `ref` string, nullable — Optional client-supplied tag used to cross-reference this node from edges in the same request, before the server assigns a UUID. Must be unique within the request.
    - `type_id` string, required
    - `name` string, required
    - `attributes` object
    - `selector` object, nullable
    - `confidence` number, nullable
  - `edges` BulkImportEdge[]
    - `edge_type_id` string, required
    - `source_public_id` string, uuid, nullable
    - `source_ref` string, nullable
    - `target_public_id` string, uuid, nullable
    - `target_ref` string, nullable
    - `attributes` object
    - `confidence` number, nullable
    - `evidence` object, nullable
