What Is n8n and How to Use It: A Complete Beginner’s Guide

If you’re exploring workflow automation, low-code tools, or ways to integrate scattered systems without heavy engineering, you’ve likely come across n8n. It’s becoming a preferred platform for creators, SaaS teams, developers, and operations managers who want to automate daily work without losing flexibility or control. Many organizations considering n8n integrations also work with platforms like HubSpot, Make, and Zapier and at Mpire Solutions, we help businesses build these experiences through automation consulting and implementation.

This guide explains what is n8n and how to use it, along with real examples, beginner steps and practical use cases.

Understanding What n8n Is

A Flexible Low-Code Automation Platform

When people ask what is n8n and how does it work, the simplest answer is:
n8n is an open-source automation tool that lets you connect apps, trigger workflows, and process data using a visual editor.

It sits between entry-level no-code automation (e.g., Zapier) and full custom development.
You get the flexibility of code when you need it, yet non-technical users can still build workflows through a drag-and-drop interface.

Key Capabilities

n8n strength comes from three areas:

Visual Workflow Builder

You build workflows using nodes each node represents an action, trigger, or transformation.

Native API Handling

Instead of being limited to predefined templates, n8n allows:

  • Custom API calls

  • Custom authentication

  • Multi-step logic

  • Math, aggregation, and formatting

This is especially helpful for businesses running custom CRM fields, complex operational logic, or multi-system integrations.

Self-host or Cloud

You can run n8n on your server for full control or use n8n Cloud.
This makes it suitable for companies needing security compliance or custom workflows.

What Is n8n and How Does It Work?

Understanding how n8n works becomes easier when you break it into three parts.

1. Triggers Start the Workflow

A trigger could be:

  • New HubSpot contact

  • A Webhook event

  • A new email in Gmail

  • A Slack message

  • A Shopify order

  • A scheduled cron job

Triggers fire the workflow and pass data forward.

2. Nodes Process and Move Data

Nodes can:

  • Add or update records

  • Query APIs

  • Format text

  • Split or merge data

  • Send email or notifications

  • Filter or route steps based on conditions

Nodes are linked visually, making the automation readable even for non-technical users.

3. Execution Runs Step by Step

Once the workflow is active, n8n runs through each step sequentially and logs the results.
You can inspect the inputs and outputs of any node to debug or refine the workflow.

How to Use n8n: A Beginner-Friendly Breakdown

1. Install or Open n8n

You can use n8n in three ways:

  • n8n Cloud

  • Docker installation

  • Local installation (Node.js)

Most beginners start with cloud for ease.

2. Explore the Editor

The editor shows a blank canvas.
This is where you drag nodes, connect them, and design workflows.

3. Add a Trigger

Common triggers include:

  • Webhook

  • Cron

  • App-specific triggers (HubSpot, Google Sheets, Notion, Slack, Airtable)

This defines when the automation should start.

4. Add Action Nodes

For example:

  • Create HubSpot contact

  • Send Slack message

  • Query Google Sheets

  • Make HTTP request

  • Format JSON

  • Push to database

You can mix and match as many nodes as needed.

5. Save and Activate

Once activated, n8n runs your workflow automatically based on the trigger conditions.

Real-Life Scenarios: Where n8n Solves Real Problems

Scenario 1: A Marketing Team Struggling with Manual Lead Processing

A SaaS team receives leads from multiple places Meta Ads, a WordPress form, and webinars.
They manually upload CSVs into HubSpot every week.

n8n solution: Automatically collect all lead sources, clean the data, dedupe records, enrich with Clearbit, and push into HubSpot instantly.

Result: Lead response becomes faster, and sales touches happen on time.

Scenario 2: An E-commerce Brand Tracking Orders Across Shopify, WhatsApp, and Google Sheets

The operations team was copying order details between channels for fulfillment.

n8n solution: A workflow that syncs Shopify orders → sends WhatsApp messages → updates Google Sheets in real time.

Result: No manual entry, fewer errors, and faster deliveries.

Scenario 3: A Small Agency Managing Client Reporting

n8n solution: A scheduled workflow that collects metrics from all tools and sends a compiled report to Slack and email.

Result: Consistent reporting and fewer missed updates.

Why n8n Is Gaining Popularity

Open Source + High Flexibility

Teams can customize logic far more than restricted no-code platforms.

Affordable

Instead of paying per automation, per task, or per record, n8n allows more flexibility with pricing and hosting.

Community and Transparency

Developers contribute nodes, troubleshoot issues, and extend n8n in ways closed platforms can’t match.
