What is n8n workflow? A-Z guide to building automated workflows

What is a workflow in n8n?

To understand n8n, we first need to clarify its core concept: the n8n workflow. Simply put, a workflow in n8n is a series of logically connected actions designed to automate a specific process from start to finish. Instead of manually handling repetitive tasks, you set it up once, and the workflow takes care of the rest.

This is a classic example of workflow automation that saves time and minimizes human error.

Key components of a workflow

Every n8n workflow is built from basic building blocks called "nodes." These nodes work together to create a complete automation system.

• Trigger Node: This is the starting point—the event that kicks off the entire workflow. A trigger can be anything, such as:
  • Scheduled: Runs at 9 AM every day.
  • App Event: Listens for a specific action in an integrated application.
  • Webhook: Receives an HTTP request from another application.
  • Manual: You click a button to start it.
• Action Node: Once triggered, the workflow performs one or more actions. Each n8n node represents a specific action within an application. Examples include:
  • Sending an email via Gmail.
  • Creating a new task in Trello.
  • Sending a message to a Slack channel.
  • Fetching data from an API.
  • Adding data to a database.
• Connection: These are the links between nodes, allowing data to flow from one to the next. The output of one node becomes the input for the following node, forming a seamless workflow.

Example: Picture a simple workflow: every minute, when a commit is added to a Google Sheet, n8n automatically retrieves the new data and sends a notification to Telegram. The whole process runs on its own without any manual intervention.

Step-by-step guide to building a workflow in n8n

Creating an n8n workflow is more intuitive than you might expect. With its drag-and-drop interface, you can build powerful automation scenarios without writing much code. Here’s a basic 3-step process:

Step 1: Define the workflow’s goal

This is the most critical step. A clear plan ensures your workflow is effective and purposeful. Ask yourself:

• What process do you want to automate? (e.g., sending welcome emails to new customers, syncing product data, generating weekly reports).
• What is the starting point (trigger)? (e.g., when a new customer signs up on your website).
• What actions need to be performed? (e.g., adding customer info to a CRM, sending a welcome email, creating a task for the sales team).
• Which applications or services need to be integrated? (e.g., HubSpot, Gmail, Google Sheets, Slack).

Step 2: Create the workflow in n8n

Once you have a plan, log into n8n and start building your new workflow.

• Add a Trigger Node:
  • In the Canvas interface, click the "+" button to add your first node.
  • Search for and select the trigger you want. For example, to start a workflow when a new row is added to Google Sheets, choose the "Google Sheets Trigger" node.
  • Configure the Trigger: Select the event (e.g., "On Row Added"), connect your Google account (via Credentials), and specify the spreadsheet to monitor.

  • 

• Connect accounts (Credentials):
  • When adding a new node for the first time, n8n will prompt you to connect the relevant account. This authentication step allows n8n to access and act on your applications. It’s secure and only needs to be done once per account.

  • 

• Add Action Nodes:
  • Click the "+" sign on the Trigger Node to add the next action node.
  • Search for and select the desired application. For instance, to send an email, pick the "Gmail" node.
  • Configure the Action: In the Gmail node, choose "Send an Email." You can use data from the previous Google Sheets node to populate fields like "To Address," "Subject," and "Body." For example, drag the "email" column from Google Sheets into the "To Address" field.

  • 

• Repeat and connect:
  • Keep adding action nodes as needed to complete your workflow.

Step 3: Test and activate the workflow

Testing is essential before going live.

• Run a test (Test Workflow): Click the "Execute Workflow" button at the bottom of the screen. n8n will run the workflow with sample data, letting you see the results at each step. This helps you spot any logical errors or misconfigurations.

• 

• Activate: Once everything works smoothly, toggle the "Active" switch in the top-right corner. From then on, your n8n workflow will run automatically whenever the trigger is activated.

Real-world examples of n8n workflows

The possibilities with n8n are limitless. Here are some practical examples to spark ideas:

• Marketing automation: This workflow tracks Google Trends, filters potential topics, generates content with AI, and posts it across multiple social media platforms.

• 

• Automated reporting: At the end of each day, it fetches data from the Google Analytics API, compiles a report, and emails it to the management team.
• AI chatbot creation: Integrates n8n with OpenAI or other language models to build smart chatbots that answer customer queries on your website or Facebook Messenger.

• 

Tips for optimizing your workflow

• Use templates: n8n offers a huge library of thousands of community-contributed workflow templates. Instead of starting from scratch, explore these templates and tweak them to fit your needs—saving tons of time.
• Add conditional logic: Use the "IF" node for conditions. For example: If the customer is from Vietnam, then send an email in Vietnamese; else, send it in English.

• 

• Handle errors: Set up an "Error Workflow" to trigger a separate workflow if the main one fails, notifying you so you can address issues quickly.
• Check periodically: Even after activation, occasionally review the execution history to ensure the workflow runs smoothly.
