Adapting GCS_Auth code example to Google Calendar -

i created github repo sbt project contains modified gcs_auth code example. modifying works google calendar. when run project console app, oauth token valid 3600 seconds, terrific.

my question is: else must in order enable app create new calendar user, , modify , delete events in user's calendar? user create events in calendar created app. understand there 'enterprise setting' have not been able find documentation on means. oauth overview: "an application has oauth consumer key , secret (roughly equivalent role account username , password) allowed act user in domain when accessing google data apis." found "additional claims" on this page , i'm puzzling out.

seems capability possible if each user accesses google calendar via domain administered via google's services. random gmail accounts not intended able grant write permission service apps. unfortunately, not meet project's needs , have write own calendar facility.
