How to Build Automation Workflows with n8n on Your VPS
What can you do in n8n?
n8n allows you to automate tasks by connecting various apps and services through an easy-to-use visual workflow editor. You can integrate APIs, handle data transformations, and trigger actions based on specific events such as receiving new emails, form submissions, or defined schedules.
Send newly received Gmail messages to a Slack channel as team notifications.
Automatically save form submissions from Typeform into a Google Sheet.
Scheduled Twitter posts automatically by pulling content from an RSS feed.
Sync new CRM data (e.g., HubSpot) with Airtable or your internal database in real time.
Trigger custom workflows via webhooks when a customer makes a purchase on your Shopify store.
This guide will walk you through how to build basic workflows in the n8n panel, hosted on your VPS. In this example, you’ll create an automation that fetches unread emails from Gmail and log their details (like Subject, From, and Date) into a Google Sheet.
Log in to your n8n panel using the email and password you created during the initial setup.
You can access your panel by visiting the following URL: https://n8n.[your-vps-hostname].gbnet.cloud
(Make sure to replace [your-vps-hostname] with your actual hostname.)
Click on 'Start from scratch' to begin creating your first workflow, as this is a new setup.
Click the '+ Add first step' button in the center of the page to select a trigger node.
You may choose a trigger that best suits your project. For this guide, we will use the trigger manually.
Once you have selected the trigger node, you can add the next nodes by clicking the '+' button after trigger node.
You may choose any node that suits your project requirements. For this guide, we will select the Gmail node.
Next, you need to select the appropriate action. Since we want to fetch unread emails, the suitable action is 'Get many messages'.
Then, you need to configure the parameters. If you have already set up Gmail credentials, you can select the available credential. If not, expand the 'Choose Credential' section and click '+ Create New Credential'.
By clicking setup new credential, a window like the one shown below will appear. To obtain the Client ID and Client Secret, you need to access the Google Cloud Platform.
You need to copy the OAuth Redirect URL and paste it into the Authorized redirect URLs field in Step 16.
In the Google Cloud Platform, you can either select an existing project or create a new one by clicking the 'Select a project' at the top left for your n8n integration.
Click on New Project to create a new project.
