I'm using Google Apps Provisioning API with gdata-java-client to manage Google Apps domain. https://developers.google.com/google-apps/provisioning/
Since Provisioning API is deprecated now, I'm considering to migrate to new Google Apps Directory API with google-api-java-client. Looks like the most of functionalities of my software can be migrated, but I couldn't find how to set "emailPermission" of the group settings. https://developers.google.com/google-apps/provisioning/#creating_a_group
It sounds like Google Apps Groups Settings API would be it, but it has far more high-functioning than Provisioning API do and I don't think these are equivalent.
Is there any equivalent API for Directory API/Admin SDK?
