Obtaining Google Ads Credentials for n8n

Follow these steps to get your Google Ads credentials for n8n:

1. Create a Google Cloud Project

If you don’t already have one, create a project in the Google Cloud Console. This project will house your Google Ads API credentials. This is a crucial first step for managing your API access.

2. Enable the Google Ads API

In your Google Cloud project, navigate to the API Library and enable the “Google Ads API.” This allows your project to access Google Ads functionality.

3. Create OAuth 2.0 Credentials

Go to the “Credentials” page in your Google Cloud project.
Click “Create Credentials” and select “OAuth client ID.”
Choose “Web application” as the application type.
Give your OAuth client a name (e.g., “n8n Google Ads Integration”).
Under “Authorized JavaScript origins,” add the URL of your n8n instance (e.g., https://your-n8n-instance.com).
Under “Authorized redirect URIs,” add the same URL, appending /rest/oauth2-credential/callback (e.g., https://your-n8n-instance.com/rest/oauth2-credential/callback). This is crucial for n8n to complete the authentication process.
Click “Create.”

4. Obtain Client ID and Client Secret:

After creating the OAuth client ID, you will see your Client ID and Client Secret. Copy these values; you’ll need them for n8n.

5. Configure n8n

In your n8n instance, go to the “Credentials” section.
Add a new credential of the “Google Ads” type.
Paste the Client ID, Client Secret, and Refresh Token that you copied earlier into the appropriate fields.
Input your Google Ads Customer ID.
Follow the on-screen instructions to authorize n8n to access your Google Ads data.

Tips and Troubleshooting

Scopes (Permissions)

Ensure you have the necessary scopes enabled for the Google Ads API. Insufficient scopes can lead to authorization errors.

Redirect URIs

Double-check that your authorized redirect URIs in the Google Cloud Console match your n8n instance URL exactly.

Client ID and Secret Security

Treat your Client ID and Client Secret like passwords. Keep them secure and do not share them publicly.

Refresh Token Security

The refresh token is also very sensitive. It should be kept safe.

Testing the Connection

After configuring the credentials in n8n, test the connection immediately to ensure it’s working correctly.
