n8n Google Integration Guide

TL;DR Key Takeaways :

Create a Google Cloud project to manage APIs and credentials for n8n integration.
Configure the OAuth consent screen to securely authorize n8n’s access to your Google services.
Set up OAuth client credentials (Client ID and Client Secret) to link n8n with Google services.
Enable APIs for the specific Google services (e.g., Drive, Gmail, Docs) you want to use with n8n.
Connect the credentials in n8n, verify the integration, and start building automated workflows with Google services.

1: Create a Google Cloud Project

Creating a Google Cloud project is the foundation for managing APIs and credentials required for n8n integration.

Log in to the Google Cloud Console.
Click on “New Project” and assign a descriptive name to your project.
Once created, select your project from the dropdown menu in the console.

This project will act as the central hub for all configurations, including API management and credential setup, making sure a structured and organized integration process.

2: Configure the OAuth Consent Screen

The OAuth consent screen is a crucial step that defines how Google authorizes n8n to access your data securely.

In the Google Cloud Console, navigate to “APIs & Services” and select “OAuth consent screen.”
Choose “External” as the user type and click “Create.”
Complete the required fields, such as the support email address, and add test users who will access the integration during development.

This configuration ensures that Google recognizes your application and securely authorizes n8n to interact with your Google services.

3: Set Up OAuth Client Credentials

OAuth client credentials, including the Client ID and Client Secret, are essential for establishing a secure connection between n8n and Google services.

In the Google Cloud Console, go to “Credentials” under “APIs & Services.”
Click “Create Credentials” and select “OAuth client ID.”
Choose “Web application” as the application type.
Enter the authorized redirect URI provided by n8n, such as https://n8n.io/oauth2/callback.

Once the credentials are generated, save the Client ID and Client Secret securely. These details will be required to configure n8n and establish the connection.

4: Enable APIs for Google Services

To allow n8n to interact with specific Google services, you need to enable the relevant APIs in your Google Cloud project.

In the Google Cloud Console, navigate to “APIs & Services” and click “Enable APIs and Services.”
Search for the APIs you need, such as Google Drive API, Gmail API, or Google Docs API.
Enable each API by selecting it and clicking “Enable.”

Repeat this process for all the Google services you plan to use. Allowing these APIs ensures that n8n can access and interact with the respective services seamlessly.

5: Connect Credentials in n8n

With your Google Cloud project and credentials ready, the next step is to connect them to n8n for secure integration.

Open n8n and navigate to the credentials section.
Create a new Google credential and input the Client ID and Client Secret obtained from your Google Cloud project.
Sign in with your Google account and grant the requested permissions to complete the connection.

This step establishes a secure link between n8n and Google services, allowing smooth data exchange and automation.

6: Finalize Integration and Test Workflows

After connecting your credentials, it’s essential to verify the integration and test workflows to ensure everything functions as expected.

Refresh n8n to confirm that the credentials are active and properly configured.
Create and test workflows that use Google services, such as automating file management in Google Drive or sending emails through Gmail.
If additional services like Google Sheets or Slides are needed, repeat the process to enable their APIs and integrate them into your workflows.

Testing ensures that your workflows are fully operational and ready to automate tasks efficiently across various Google services.

Effortless Integration for Enhanced Automation

Setting up Google credentials in n8n is a straightforward yet powerful process that enables seamless integration with Google services. By creating a Google Cloud project, configuring the OAuth consent screen, allowing APIs, and connecting credentials, you can unlock the full potential of n8n for automating tasks. Whether you’re managing files in Google Drive, sending emails through Gmail, or working with documents in Google Docs, this integration provides a robust platform for streamlining workflows and enhancing productivity.
