When enabling "Google Workspace API" integration by clicking on Authenticate with Google Workspace, integration fails with the following error:

503 - Service Unavailable

• Google Workspace
• Provisioning
• Error
• Okta Identity Engine (OIE)
• Okta Classic Engine

This error indicates the Google Workspace server is temporarily unable to handle requests, usually due to overloading, maintenance, or backend issues.

To resolve the issue, follow the steps mentioned below:

1. After some time, retry authentication by navigating to the Okta Admin Console > Applications > Applications > Google Workspace > Provisioning tab, then clicking Configure API Integration.
2. Select Enable API integration, and then click Authenticate with Google Workspace.
3. Enter the Google Workspace Admin account credentials:
   1. Enter the admin username.
   2. Enter the admin password.
   3. Review the list of permissions Google will grant Okta to perform in the Google Workspace tenant. If acceptable, click Allow.
4. Back on the Provisioning page in Okta, a message confirming successful authentication will be seen. Click Save.
