The Three Building Blocks
Every n8n workflow has the same structure, regardless of complexity.
Trigger — What starts the workflow. This could be a webhook receiving an HTTP request, a cron schedule firing at a set time, a new row appearing in a database, a file being dropped in a folder, or a manual run you kick off from the interface. Every workflow has exactly one trigger node.
Process — What happens to the data. This is where you transform, enrich, filter, or route the data that came in. A workflow might have zero process nodes (trigger directly to output) or twenty. Most useful workflows have two to five.
Output — What the workflow does with the result. Send a notification, write to a database, make an API call, create a file, update a spreadsheet.
Understanding this structure means you can read any workflow and understand what it does before you look at the configuration of individual nodes.
