# Workflow Retriever node

Use the Workflow Retriever node to retrieve data from an n8n workflow for use in a Retrieval QA Chain or another Retriever node.

On this page, you'll find the node parameters for the Workflow Retriever node, and links to more resources.

```{include} ../../../../../_snippets/integrations/builtin/cluster-nodes/sub-node-expression-resolution.md

```

## Node parameters

### Source

Tell n8n which workflow to call. You can choose either:

* **Database** and enter a workflow ID.
* **Parameter** and copy in a complete [workflow JSON](/08-0-0-Workflow/workflows/export-import.md).

### Workflow values

```{include} ../../../../../_snippets/integrations/builtin/cluster-nodes/langchain-sub-nodes/workflow-values.md
