I have been trying using Google Analytics extension to get my data from GA to my data base but it seems there is some error in Google Analytics Connection extension as only profile ID option is appearing rest are not coming.
The other thing you need to ensure is that the service account has been added as a user to the Google analytics account/property you want access to. (add the service account in the same way you add a regular user)
Google API authentication is working fine with me as well the problem with very next step in Google Analytics connection where we generally setup project name, profile name etc but I am not getting those option in connector except profile id
