Node types: Trigger and Action

There are two node types you can build for n8n: app nodes and trigger nodes.

Both types provide integrations with external services.

Trigger nodes

Trigger nodes start a workflow and supply the initial data. A workflow can contain multiple trigger nodes but with each execution, only one of them will execute, depending on the triggering event.

Action nodes

Action nodes perform operations as part of your workflow. These can include manipulating data, and triggering events in other systems.
