I am getting start with Google Apps Admin SDK > Email Audit API, I can successfully call the API
GET https://apps-apis.google.com/a/feeds/compliance/audit/mail/monitor/{domain name}/{source user name}
using OAuth token authorized by a super admin account, but I cannot use the super-admin to build my service due to permission issue.
We have another account specific for using this API, we want to setup a custom role for this account to minimize to permission grant to this account, but we fail to find the right permission for Email Audit API.
So my question is: What is the minimal roles/permission in google admin panel for the user be able to use ALL Email Audit API feature?
