n8n Full Course – Architect Scalable AI Automations from Scratch

This freeCodeCamp.org course, credited to @automationsbyrahul in the description, runs about 43 minutes and teaches n8n by building a series of workflows that grow in scope. The creator lists chapter times in the description, and the course moves from setup to the concerns of running automations in production.

It opens at 0:00 with an introduction to n8n and an overview of the course. At 1:45 it turns to getting started: the canvas, hosting choices and setup. The first build, at 4:44, is a pipeline that takes a form submission, passes it through an AI step and sends an email. A second workflow at 7:44 is a chatbot for a sales CRM.

At 10:21 the course looks closely at the HTTP Request node and uses it to call APIs and scrape data. Document processing follows at 13:06, with fields pulled out of shipping documents. At 15:46 it separates AI agents from plain LLM calls and builds an agent that can search the web and send email. Google Sheets appears at 18:38 as a knowledge base the workflows read from.

The second half moves toward systems that run on their own. Memory comes up at 22:01, comparing short-term memory with long-term persistent memory. At 24:37 several agents work together in a content production pipeline. An event-driven setup for qualifying leads and sending alerts starts at 27:28, and at 32:25 a human approval step is added through Slack.

The last two chapters cover operations. From 34:40 the course handles production errors with retries and fallbacks. From 38:12 it covers workflow monitoring, observability and tracking token costs.

The description does not name the n8n version, the hosting plan or the AI model provider used, and no transcript was available on the watch page, so those details are unknown. The chapter times make it easy to jump straight to one topic, such as Slack approvals or error handling, without watching from the start. The early chapters on the canvas and the first two workflows are the natural entry point for anyone who has not opened n8n before.
