Automate Tasks Without Code: Your Guide to Using n8n

Do you want to automate tasks without writing a single line of code? If yes, you’re in the right place. In this tutorial, we’ll explore how to create your first automated workflow using n8n, a powerful open-source automation tool.

What Exactly is n8n?

At its core, n8n connects different applications, automates repetitive tasks, and streamlines operations—all without extensive coding. If you’re familiar with services like Zapier or Make.com, n8n operates in a similar space but offers a crucial advantage: flexibility through self-hosting and customization.

This tool is incredibly beneficial for various professionals—writers, developers, marketers, and beyond. Its visual, node-based workflow builder makes it intuitive to use. Imagine constructing with digital LEGOs; you drag and drop different nodes (each representing an app or action) and connect them to create a workflow.

The Advantage of Open Source

One of the standout features of n8n is that it’s open-source. This means it has a strong, supportive community and is constantly evolving. Plus, the option to self-host gives you complete control over your data and infrastructure.

For instance, you could automate data processing tasks that traditionally require building custom applications. Imagine automatically gathering data from a form and sending a summary to your team’s Slack channel every day. The options are limitless!

Getting Started with n8n

Step 1: Set Up an Account

1. Navigate to the n8n Website: Open your browser and go to n8n.io.

2. Sign Up: Click the “Get Started” button, which will direct you to the registration page.

3. Choose Your Plan: While n8n offers a cloud-hosted version called n8n.cloud with different subscription plans, you can start with a free trial. This is perfect for testing features and learning the tool.

4. Log In: Once registered, log into your dashboard at app.n8n.cloud. Click the orange button that says “Open Instance” to enter your workflow canvas.

If you have technical skills, there’s also a free Community Edition that you can host on your server. This option provides complete functionality without the need for a subscription.

Step 2: Building Your First Workflow — A Daily Weather Notifier

Let’s dive into creating a practical application—a weather notifier that sends a daily message to your Telegram account sharing the weather forecast for Bangkok.

Step 1: Create a New Workflow and Set the Trigger

• On your dashboard, click the “Start from scratch” button to open a blank canvas. Every workflow begins with a trigger—a specific event to start the automation.

• In the configuration panel on the left, set the “Trigger Interval” to “Days” and “Trigger at Hour” to 7 am. This means our workflow will run daily at 7 AM.

Step 2: Get the Weather Data with an HTTP Request

With our trigger in place, it’s time to fetch weather data:

• Click the plus (+) icon next to your Schedule Trigger node.
• Search for “HTTP Request” in the “What happens next?” menu and select it.

To find a suitable API for weather data, visit open-meteo.com. Configure the forecast you desire—select “Temperature” and “Rain” for the hourly metrics, and copy the generated API URL.

Return to n8n and place the URL in the HTTP Request node, ensuring that the “Method” is set to GET.

You can test the connection by clicking the “Execute step” button. You should see output data in JSON format, which we’ll use in the following steps.

Step 3: Send the Notification to Telegram

Now for the exciting part: sending the weather data as a Telegram message.

• Click the plus (+) icon after the HTTP Request node, search for “Telegram,” and select it.

• Connect Your Account: You’ll need to provide your Telegram credentials. For this, create a bot using Telegram’s BotFather, who will give you an Access Token. Paste this token into n8n’s field and save it.

• Configure the Message: Provide your unique “Chat ID”—this identifies the chat where the message will be sent. In the “Text” field, you can combine static text with dynamic data from your HTTP Request.

For example, to construct a message saying, "The weather today is X°," you would include the corresponding temperature data by dragging it to the text box, creating an expression like this: {{ $json.hourly.temperature_2m[7] }}.

After composing your message, test it by clicking “Execute step” to ensure it’s working as planned.

Step 4: Activate Your Workflow

After ensuring everything is functioning:

1. Name your workflow—something like “Weather To Telegram.”
2. Click the “Save” button.
3. Toggle the switch at the top to turn it from “Inactive” to “Active.”

Congratulations! You’ve built a useful application that sends you a daily weather notification—all without writing a line of code.

Automation with Templates

If creating workflows from scratch seems intimidating, n8n has a fantastic feature: a library of over 2,700 workflow templates. You can browse these templates by category on n8n.io/workflows.

To use a template:

• Find one that suits your needs, click “Use for free,” and copy the JSON.
• Create a new workflow in n8n, and simply paste the JSON into your canvas. The entire workflow will appear, ready for customization.

Using templates is a great way to learn and quickly build complex automation.
