Sub-workflow (n8n)
also sub-workflow
In n8n, a sub-workflow is a separate workflow called by another via the Execute Workflow node, enabling reusable, modular logic.
Analogy
Like a function you call from many places instead of copying the same code.
Why it matters
Sub-workflows keep complex automations modular and reusable, reducing duplication across builds.
In practice
A reusable 'send Slack alert' sub-workflow called by several parent workflows.
