subflow

Call another flow in the same workspace (depth and cycle guards)

Runs another flow by id and returns that flow’s output node result. Depth is capped (default max 5); cyclic call stacks are rejected. See SECURITY.md.

Calls another flow. Multiple outgoing edges (fan-out) share the same output.

Data

Field	Type	Description
`label`	string	Optional UI label
`flowId`	string	Target flow id (filename without `.flow.json`)
`input`	object	Optional map of string templates → subflow run input fields

Input / output

	Value
Execute input	Previous node output (not automatically passed unless you map it in `input`)
Output	Subflow’s flow output value

Examples

{
  "id": "callEcho",
  "type": "subflow",
  "data": {
    "flowId": "echo-subflow",
    "input": {
      "message": "foreach count={{nodes.mapIds.count}}"
    },
    "label": "Call echo-subflow"
  }
}

The sample workspace includes echo-subflow for this pattern; kitchen-sink calls it on the demo path.
