The n8n ecosystem extends beyond built-in nodes. Community nodes add integrations for services not yet officially supported, and sub-workflows let you build reusable automation components.
Community Nodes
Install third-party nodes from the n8n community: 1. Go to Settings → Community Nodes 2. Search for the package name 3. Install and restart
Sub-Workflows
Use the "Execute Workflow" node to call another workflow as a function. This promotes reusability and keeps complex automations manageable.
