Course overview

Repetitive tasks such as copying form data into spreadsheets, sending confirmation emails, compiling daily totals or alerting the team about new orders take up a large share of staff time every week. Workflow automation lets systems hand work to each other automatically. n8n is a fair-code tool that you can host on your own server. You connect hundreds of services by dragging and dropping nodes without writing code, and add code when you need it, so businesses of any size can start automating at low cost.

This course takes learners through n8n version 2, from installing it with Docker Compose and PostgreSQL to understanding nodes, items and expressions, using different triggers and transforming data. Learners connect Google Workspace, databases and external services through APIs, send alerts through Telegram or LINE, design maintainable workflows with sub-workflows and handle failures with error workflows. They then get started with AI agents and with running n8n in production. It closes with a workshop that builds a business automation system from start to finish. (3 days, 6 hours per day, 18 hours in total, Beginner to Intermediate level.)

Curriculum

Course Details

This course is the 2026 edition that replaces the previous n8n workflow automation course for modern businesses, which was taught on n8n 1. It runs for 3 days, 6 hours per day (18 hours in total, 09:00-16:00), as lectures with labs and workshops based on real business tasks. Beginner to Intermediate level. The content has been moved entirely to n8n 2, including workflow

publishing, task runners and the new security defaults. New topics include the Form Trigger, data tables, alerts through Telegram and the LINE Messaging API, and an introduction to AI agents. Learners who want to go deeper into AI agents and MCP can continue with Agentic AI Development using n8n and MCP. Learners take home a lab guide, sample workflows for every lab and a docker-compose file.

Frequently asked questions

What is n8n and how does it differ from Zapier or Make?

n8n is a fair-code workflow automation tool where you connect services by dragging and dropping nodes, much like SaaS automation tools. The key difference is that you can host it on your own server, so data stays inside the organisation and internal business use is not charged per task run. You can add JavaScript or Python when standard nodes are not enough, and it has built-in AI agents. If you would rather not run a server, n8n Cloud is also available.

How do you install n8n with Docker Compose?

Write a docker-compose file with an n8n service and a PostgreSQL service, give each a data volume, and set the key environment variables such as the database connection, timezone, N8N_ENCRYPTION_KEY and webhook URL, then run docker compose up. The first visit to the web page creates the owner account. Keep the encryption key safe, because it decrypts every stored credential, and for production set up a domain with HTTPS through a reverse proxy.

How do you set up an alert when an n8n workflow fails?

Create a separate workflow that starts with an Error Trigger and add a node that sends a message, such as Telegram, the LINE Messaging API through HTTP Request, or email, including the workflow name, the error message and a link to the failed execution. Then open the settings of each workflow you want to watch and select this error workflow. Combine it with Retry on Fail on nodes that call external services, so n8n tries again first and alerts you only when it cannot recover.

Who is the n8n Workflow Automation for Business course for, and what should I know beforehand?

It suits SME owners and start-ups, operations, sales and marketing staff, in-house IT teams, freelancers, and developers and students. You do not need to know how to program, only to be comfortable with a computer and online services such as email and Google Sheets. Some database or basic JavaScript knowledge helps you pick things up faster.

What will I be able to do after the n8n Workflow Automation for Business course?

You will be able to install n8n with Docker, design workflows with triggers and data transformation, connect Google Workspace, databases and external services through APIs, send alerts through Telegram or LINE, structure work with sub-workflows, handle failures with error workflows, start using AI agents for business tasks and run n8n in production. Participants who complete the training receive a Certificate of Completion with its own number, which can be verified online.

Can the n8n Workflow Automation course be run in-house for our team?

Yes. It can be run in-house for your team, with examples adapted to your own work, such as your real business processes and the systems your organisation already uses, or a focus on installing n8n on your own servers. You can request a quotation from this page, or contact us on LINE @itgenius or by phone on 02-570-8449.
