Introduction

This tutorial will guide you through the basics of using n8n, a powerful workflow automation tool. Whether you're new to automation or looking to enhance your skills, this step-by-step guide will help you create your first workflow effectively.

Step 1: Setting Up n8n

1. Installation

   • Visit the n8n website to download the latest version.
   • Follow the instructions to install it on your system, whether on Windows, macOS, or Linux.
   • Consider using Docker for an easy setup by running the following command:

     docker run -it --rm \
       --name n8n \
       -p 5678:5678 \
       n8nio/n8n
     

2. Accessing n8n

   • Open your web browser and go to http://localhost:5678 to access the n8n editor.

Step 2: Creating Your First Workflow

1. Start a New Workflow

   • Click on the "New" button to create a new workflow.

2. Adding Nodes

   • In n8n, a workflow is made up of nodes. Click on "Add Node" to select the type of service you want to integrate (e.g., HTTP Request, Email, etc.).
   • For example, to send an email:
     • Search for the "Email" node and select it.
     • Fill in the necessary fields like sender email, recipient email, subject, and message body.

3. Connecting Nodes

   • Drag a line from the output of one node to the input of another to establish a connection.
   • This defines the flow of data between your nodes.

Step 3: Configuring Trigger Nodes

1. Setting Up Triggers

   • Add a trigger node that will initiate your workflow. Common triggers include webhook or cron jobs.
   • For a webhook:
     • Select the "Webhook" node and set it up to receive data when an event occurs.

2. Testing Your Trigger

   • Once configured, test the trigger by sending a request to the webhook URL provided by n8n to ensure it is working correctly.

Step 4: Executing the Workflow

1. Running the Workflow

   • After setting up your nodes and connections, click the "Execute Workflow" button to run it manually.
   • Monitor the execution to ensure all nodes are functioning as expected.

2. Debugging Issues

   • If errors occur, check the nodes for misconfigurations.
   • Use the execution log to trace any issues and adjust settings accordingly.

Step 5: Saving and Activating Your Workflow

1. Saving Your Workflow

   • Click on the "Save" button to store your workflow.
   • Name your workflow descriptively for easy identification later.

2. Activating Your Workflow

   • To run the workflow automatically based on triggers, activate it by toggling the activation switch to "On".

Conclusion

You have now learned the foundational steps to get started with n8n and create your first workflow. With practice, you can explore more complex integrations and automate various tasks effectively. As a next step, consider experimenting with different nodes and triggers to enhance your automation capabilities. Happy automating!
