n8n Zero to Hero · Level 1: The Automation Playground · Episode 03
My First Green Button
The button that says GO — setting up and testing your first Trigger node.
What this episode is about
In Episodes 1 and 2 you placed nodes without knowing what they actually do — today that changes. Every n8n workflow needs a starting point, and the Manual Trigger is the simplest one there is: a button that says GO. We add it to the canvas, press it, and watch it actually run — reading the green checkmark that means "this worked," and peeking at the tiny bit of output data it produces. We also look ahead at the other kinds of triggers you'll meet later in the course, ones that fire on a schedule or the moment a message arrives from the internet.
