n8n Automation Tutorial: Build Your First Workflow in 15 Minutes (No Code)

n8n is an open-source workflow automation tool that lets you connect apps and automate tasks — without writing code. Think of it as a visual programming tool where you connect blocks to create automated workflows.

In this tutorial, you'll build a real automation from scratch in just 15 minutes.

What is n8n?

n8n (pronounced "nodemation") is a free, open-source workflow automation tool. It's similar to Zapier or Make.com, but with key advantages:

  • Self-hosted: You own your data and workflows
  • Open source: Free to use, modify, and extend
  • 500+ integrations: Connect with almost any app or service
  • AI-native: Built-in AI nodes for LLM integration
  • Code when needed: Add JavaScript/Python for custom logic

Tutorial: Build an Automated Email Summary Workflow

Let's build a practical workflow: automatically check an RSS feed for new articles and send a daily email summary.

Step 1: Create a New Workflow

  1. Click "Add workflow" in the n8n dashboard
  2. Name it "Daily Article Summary"

Step 2: Add a Schedule Trigger

  1. Click the + button to add a node
  2. Search for "Schedule Trigger"
  3. Configure it to run daily at 8:00 AM

This tells n8n when to run your automation.

Step 3: Add an RSS Feed Node

  1. Click + to add another node after the trigger
  2. Search for "RSS Feed Read"
  3. Enter the RSS feed URL (e.g., https://dev.to/feed)
  4. This fetches the latest articles from the feed

Step 4: Filter Recent Articles

  1. Add an "IF" node
  2. Set the condition: Published Date is after yesterday
  3. This filters to only articles published in the last 24 hours

Step 5: Format the Summary

  1. Add a "Set" node (or "Code" node for more control)
  2. Map the article titles and URLs into a formatted email body

Step 6: Send the Email

  1. Add an "Email Send" node
  2. Configure your SMTP settings or use Gmail integration
  3. Set the recipient, subject ("Your Daily Tech Digest"), and body

Step 7: Test and Activate

  1. Click "Test workflow" to run it manually
  2. Check that the email is sent correctly
  3. Click "Activate" to make it run on schedule

Key n8n Concepts

Nodes

Building blocks of a workflow. Each node performs an action — fetching data, transforming it, or sending it somewhere.

Connections

Lines between nodes that pass data from one step to the next.

Triggers

Special nodes that start a workflow — on schedule, when a webhook is received, when a file changes, etc.

Expressions

Dynamic values using {{ }} syntax. Example: {{ $json.title }} references the title field from the previous node's output.

Workflow Ideas for Beginners

  1. Lead notification: When a form is submitted → Send a Slack message
  2. Social media scheduler: RSS feed → Format post → Post to Twitter/LinkedIn
  3. Invoice reminder: Check spreadsheet → If overdue → Send reminder email
  4. Meeting notes: Google Calendar event starts → Create a Notion page
  5. Data backup: Schedule → Pull data from API → Save to Google Sheets

n8n with AI

n8n has native AI integration. You can:

  • Add an OpenAI node to summarize, classify, or generate text
  • Build AI chatbots using n8n's chat trigger + LLM node
  • Create RAG workflows that search documents and answer questions
  • Chain multiple AI calls for complex reasoning tasks
