Cannot View Logs in Splunk after Integrating with Google Workspace

[ShuKinTa]

This is regarding the integration between Splunk and Google Workspace.

I have followed the documentation below to configure the integration, but the log data is not being ingested into the specified index in Splunk, and I cannot view the Google Workspace logs on Splunk. Additionally, there are no apparent errors after the integration setup.

I would appreciate any advice or precautions to take when installing the Add-on for Google Workspace.

# Additional info

When use a group email address (with owner permissions) and configure the integration between Splunk and GWS, an authentication error occurs. However, if use a user name email address, the integration is successful. 

I thought that granting owner permissions would allow the group email address to integrate successfully just like a user email address, but this was incorrect.

9. In the Service account details page for your new service account, perform the following steps:

~~~~~ Omitted ~~~~~

h. Navigate to the user name email address that has Owner permissions. Copy the email address.

I think its a permission issue, Google Workspace user should have a “Organization Administrator” role. That’s the only requirement for the account. you account might be read only?
