Our expert team is currently recording the visual guide for n8n Introduction.
The Core Concept
n8n is a powerful, visual workflow automation tool. Imagine you want to save every new email attachment to your Google Drive, and then get a Slack message about it. Instead of doing this manually every day, or paying a developer to write a complex script, n8n lets you drag and drop 'Nodes' (apps) onto a canvas and draw lines between them to automate the whole process.
Because n8n is 'fair-code', you can host it yourself for free or use their cloud version. It's the perfect middle-ground between simple tools like Zapier and writing custom Python scripts. In this lesson, we will look at how a basic trigger-and-action workflow operates.

Code & Implementation
// n8n is a visual tool, so you don't write code to build basic workflows!
// Behind the scenes, a workflow is just a JSON file connecting nodes:
{
"nodes": [
{
"parameters": {},
"name": "Start",
"type": "n8n-nodes-base.start"
},
{
"parameters": { "url": "https://api.github.com" },
"name": "HTTP Request",
"type": "n8n-nodes-base.httpRequest"
}
],
"connections": {
"Start": {
"main": [ [ { "node": "HTTP Request", "type": "main", "index": 0 } ] ]
}
}
}Expected Output
Workflow executed successfully. Data fetched from HTTP node.

The Challenge
You don't need the software yet. On a piece of paper or in a text file, write down a 3-step automation you wish existed in your life.
Helpful Hints
- •Step 1 should be a Trigger: 'When this happens...'
- •Step 2 should be an Action: 'Do this...'
- •Step 3 should be another Action: 'And then do this...'
