Connecting Ibexa Connect to Google services using a custom OAuth client

In this article, we will show you how to create your own project in Google Cloud Console and a custom OAuth client. This is useful for connecting restricted Google services, like Google Drive or Gmail*,* to Ibexa Connect.


The following procedure is intended for:

  • Personal use ( and users)
  • Internal use (Google Workspace (formerly GSuite) users that prefer to use a custom OAuth client)


  • a Google account

Follow these steps to create a custom OAuth client for Google services:


You will not be charged when selecting this option. For more details, refer to Google's Exceptions to verification requirements.

For the Scopes section:

Click the Add or Remove Scopes button to add the required scopes.

Enter the required scopes for the Google service you want to connect to Ibexa Connect by checking the corresponding box for each required scope.

Google Drive

For the Test Users section:


The Optional Info section is displayed only for non-Google Workspace users and does not contain any required fields.


This step is required, otherwise, you won't be able to establish a connection with Ibexa Connect.

Click Add users to add the email address associated with the Google account you want to connect to Ibexa Connect.

  1. Sign in to Google Cloud Platform using your Google credentials.

  2. Open the Dashboard, and click the CREATE PROJECT button.


  3. Choose a name for your project, then click Create.


  4. Click Enable APIs and services.
