Sub-flow node

Sub-flow (sub_flow) calls another flow as a step of this one: its input goes in, its Flow Output comes back. The composition primitive for multi-agent architectures and shared logic.

Configuration

Open the node (double-click) to edit it. Key fields:

• Node ID / Name — the identifier used in variables and the display name on the canvas.
• Target flow — which flow to execute.
• Input mapping — which values to pass it.

Inputs & outputs

It receives mapped inputs and emits the target flow's output. Downstream nodes reference its output with {{node_id.field}} — see the variables reference.

Example

Chat Input → Sub-flow (validador) → Sub-flow (agente ventas) → Chat Output
