You’ll need to set up your environment before creating your first n8n workflow. This setup requires key decisions about hosting and account creation.

Cloud vs Self-hosted: Which One to Choose?

You must choose between cloud-hosted and self-hosted options as you begin with n8n. Each option brings unique benefits:

Cloud (Hosted by n8n)

• The quickest way to start with zero maintenance
• The n8n team handles automatic updates
• Perfect for beginners and non-technical users
• You can sign up and build workflows within minutes

Self-Hosted

• Complete data privacy and control
• Your data stays on your server
• Advanced users find this more suitable
• Sensitive information and custom needs work better here

The cloud version works best for most beginners. Developers and businesses that need strict data control might choose self-hosting.

Installing n8n with Docker or VPS

Docker provides the most reliable method for installation if you select self-hosting. Your system stays clean and isolated with Docker, which makes database management simple and prevents compatibility issues.

Docker Engine and Docker Compose must be installed on your system first. A simple command then creates a volume for persistent data, downloads the needed image, and launches the container.

You can also set up n8n on a Virtual Private Server (VPS) from providers like DigitalOcean or AWS. This approach needs more technical expertise but gives you more flexibility.

Creating Your First n8n Account

The cloud option requires a visit to the official n8n website, where you’ll click “Start for Free” or “Get Started for Free”. Your signup involves:

1. Entering your full name, email, password, and account name
2. Selecting your skill level and company information
3. Clicking “Start Automating” to access your workspace

The n8n interface appears after login. You can start creating workflows by clicking the orange “Create Workflow” button in the top right corner.

These steps prepare you to build your first automated workflow using n8n’s powerful node-based system.

Understanding the Core Building Blocks

Your n8n environment setup is complete. Let’s look at the basic components that make n8n workflows work. Nodes are the building blocks of your automation, and each one performs specific functions.

Trigger Nodes: Starting Your Workflow

Trigger nodes kick off your workflow and decide when your automation begins. You’ll recognize them by their rounded left edge and lightning bolt icon instead of an input connector. The common triggers include Manual Trigger for testing, Schedule Trigger for time-based operations, Webhook Trigger that responds to external requests, and App Event Triggers that react to connected services. These triggers watch for specific events before they start running your workflow.

Action Nodes: Connecting to Apps

Action nodes take over after a trigger starts your workflow. They handle the actual tasks by connecting to external services, working with data, or running specific operations. Each action node represents a task like sending emails, updating databases, or posting messages to chat platforms. Most workflows link several action nodes together to complete complex processes.

Logic Nodes: Branching and Filtering

Logic nodes make your workflows smarter through conditional branching. IF nodes create true/false paths based on conditions, switch nodes route data through multiple paths, and merge nodes combine data from different branches. These nodes help workflows make data-driven decisions instead of following a straight path.

HTTP Request Node for Custom APIs

The HTTP Request node is one of n8n’s most flexible tools. This node connects with any service that has a REST API, even without a dedicated n8n integration. You can set up HTTP methods (GET, POST, PUT, etc.), add authentication, and adjust request headers or query parameters. The HTTP Request node gives you a solution for custom integrations or services without dedicated n8n nodes.

Using Expressions and JSON in n8n

n8n expressions use JavaScript snippets in double curly braces {{ }} to handle data dynamically. These expressions let you access data from previous nodes, change values, and create conditional logic without extra nodes. The JSON (JavaScript Object Notation) structure is vital since most n8n data flows as JSON objects. The combination of expressions and JSON knowledge helps you build advanced workflows that handle and transform data well.

Step-by-Step: Build a Daily Weather Email Workflow

Let’s put our n8n knowledge to work by creating a useful workflow that sends daily weather updates to your inbox. This hands-on example shows how n8n automation connects different services to create something you’ll actually use.

1. Add a Schedule Trigger Node

The Schedule Trigger node serves as your workflow’s starting point. You can set it to run daily at 7:00 AM with these settings:

• Trigger Interval: Days
• Days Between Triggers: 1
• Trigger at Hour: 7 am
• Trigger at Minute: 0

Your n8n instance’s timezone setting affects the Schedule Trigger, so double-check this setting for accurate timing.

2. Connect to OpenWeather API

The next step needs an HTTP Request node to fetch weather data. You’ll need to sign up for a free OpenWeatherMap account to get your API key (it has 400 free calls daily). Set up the node like this:

• Method: GET
• URL: api.openweathermap.org/data/2.5/weather?q=YOUR_CITY&units=metric&appid=YOUR_API_KEY
• Authentication: Query Auth (parameter: “key”, value: your API key)

3. Format the Weather Data with Set Node

The weather data needs organization through a Set node. JSON mode gives you better control over data structuring. You can pull out important details like temperature, description, and humidity from the previous node’s output. Create your message with:

{"weatherSubject": "Today's Weather in {{$node["HTTP Request"].json["name"]}}",
  "weatherBody": "Current temperature: {{$node["HTTP Request"].json["main"]["temp"]}}°C"}

4. Send Email via Gmail Node

The Gmail node handles sending your weather report. Start by authenticating with your Gmail account using OAuth2. Then set these options:

• To: Your email address
• Subject: Use the weatherSubject variable
• Text: Use the weatherBody variable
• HTML: Optional for formatted emails

5. Test and Debug the Workflow

The workflow needs testing. Run a manual test by clicking “Execute Workflow”. Each node’s output appears when you click it after execution. The execution log at the bottom of the screen shows any errors. Make your adjustments and activate the workflow to start getting daily updates.

Expanding Your First Workflow with Smart Add-ons

Your first workflow is running smoothly, and now you can improve it with powerful features that make n8n automation strong and adaptable.

Adding Conditional Logic with Switch Node

The Switch node raises your n8n workflows by routing data through multiple paths based on conditions. Unlike the simpler IF node, Switch supports numerous output routes through two main modes. Rules mode helps you create specific matching conditions for different data types. Expression mode lets you determine outputs with JavaScript programmatically. This advanced routing becomes valuable when you handle complex data scenarios. Your workflow can respond intelligently based on the information it processes.

Logging Data to Google Sheets

Google Sheets integration in your workflow creates powerful data logging capabilities. This integration makes shared reporting and data syncing possible across platforms. To cite an instance, see how you can set up your weather workflow to archive daily temperatures and create historical records automatically. This method works great for error logging—you can document automation failures with detailed diagnostics.

Using Templates from the n8n Library

You can save development time by utilizing pre-built templates from the n8n library. These ready-made workflows are perfect starting points for common automation needs. Many templates include error handling, notification systems, and optimization techniques that experienced users have developed. You can customize these templates to fit your specific needs instead of building complex workflows from scratch.

Pin Data and Reuse for Testing

Data pinning makes workflow development quick by letting you “freeze” a node’s output. This technique stops the unnecessary execution of time-consuming upstream nodes during testing. A distinctive blue icon appears on your canvas to identify pinned nodes. The output editing feature lets you paste previously generated data. This makes debugging efficient because you don’t need to trigger external services repeatedly.
