When a form is submitted, this follow-along lesson teaches how data passes between nodes, execution modes, looping and basic debugging.
What it does
# Let's Learn n8n! Lesson 1 This is a follow-along workflow that will teach you how to develop in n8n, from scratch. n8n is a powerful and flexible tool -- but it's quirky, the AI help is often wrong, and the docs are not sufficient or effective. Using this workflow you will learn concepts 'live', and can then refer back to these examples as you build your own workflows. Because this is a live script, you also will see that its working with the latest version, unlike many of the resources you will find on youtube etc. n8n changes very fast, so understandably things that worked even a few months ago may no longer apply to the current version. ### Who is this for? You should have familiarity with: - programming (any language) - javascript / typescript - REST API concepts - JSON data If any of those are not in your wheelhouse, building in n8n will be much more difficult, despite what you are told. Consider that using n8n may be difficult without this knowledge. ## Ok, Lets Continue Below...
