How do you set up your first n8n workflow?

Prerequisites

Before starting, organizations need either an n8n Cloud account or a self-hosted n8n instance. n8n Cloud offers a free tier with 5 active workflows and requires no setup. Self-hosting requires Docker or a direct installation on a Linux server with Node.js 18+.

Step 1: Access the n8n Editor

For n8n Cloud, sign up at n8n.io and open the workflow editor from your dashboard. For self-hosted instances, navigate to your n8n URL (typically https://your-domain.com or http://localhost:5678). The editor presents a blank canvas with a "+" button in the center.

Step 2: Create a New Workflow

Click the "+" button or use the top-left menu to create a new workflow. Name it something descriptive (e.g., "Google Sheets to Slack Notification"). n8n saves workflows automatically as you build them.

Step 3: Add a Trigger Node

Every workflow starts with a trigger. Click the "+" button on the canvas and search for your trigger type:

• Schedule Trigger: Runs on a cron schedule (e.g., every 5 minutes, daily at 9am)
• Webhook: Triggered by an HTTP request from an external service
• App Trigger: Triggered by an event in a connected app (e.g., new row in Google Sheets)

For this tutorial, select Google Sheets Trigger and choose "Row Added" as the event.

Step 4: Configure Credentials

n8n will prompt you to create a Google credential. Click "Create New Credential" and follow the OAuth flow:

1. Sign in with your Google account
2. Grant n8n access to Google Sheets
3. The credential is saved and encrypted in n8n's credential store

Select the specific spreadsheet and sheet organizations want to monitor.

Step 5: Add Action Nodes

Click the "+" button to the right of your trigger node to add action steps. For a Google Sheets-to-Slack workflow:

1. Add a Slack node
2. Create a Slack credential (Bot Token or OAuth)
3. Select the channel to post to
4. Map data from the Google Sheets trigger to the Slack message

Use expressions (click the gear icon on any field) to reference data from previous nodes. For example: {{ $json.Name }} submitted a new entry will insert the "Name" column value from the Google Sheet row.

Step 6: Test Your Workflow

Click "Test workflow" in the top-right corner. n8n will execute each node sequentially and show the output data on the canvas. Green check marks indicate success; red X marks indicate errors. Click any node to inspect its input and output data.

If testing with a Google Sheets trigger, you may need to add a test row to the spreadsheet first, or use the "Execute Node" feature to simulate trigger data.

Step 7: Activate the Workflow

Once testing passes, toggle the "Active" switch in the top-right corner. The workflow is now live and will trigger automatically when new rows are added to your Google Sheet.

Step 8: Monitor Executions

Open the "Executions" tab (left sidebar) to see a log of all workflow runs. Each execution shows:

• Start and end time
• Status (success or error)
• Data processed at each node
• Any error messages with stack traces

Set up error notifications by adding a workflow-level error handler that sends a Slack message or email when any execution fails.

Common Patterns for First Workflows

Editor's Note: Google Sheets-to-Slack is our standard onboarding exercise for clients new to n8n. First-timers typically complete it in 12-18 minutes. The most common stumbling point is the Google OAuth consent screen setup — Google requires configuring a Cloud project, enabling the Sheets API, and creating OAuth credentials. This adds 5-10 minutes for users without an existing Google Cloud project. We pre-configure the Google credentials for client onboarding sessions to avoid this friction.
