What Are Sub-Workflows in n8n?
A sub-workflow is a separate workflow you call from another workflow, like a reusable function. The calling workflow uses the Execute Sub-workflow node, and the sub-workflow runs from its own Execute Sub-workflow Trigger, accepts input data, and returns a result.
How to Use Sub-Workflows in n8n
Build the reusable logic as its own workflow that starts with an Execute Sub-workflow Trigger. In the main workflow, add an Execute Sub-workflow node, select that workflow, and pass in the data it needs. The sub-workflow runs and hands its output back to the main flow. Use sub-workflows to reuse one tested process across many automations, keep large workflows readable, and isolate logic you change often.
