When your application requests private data, the request must be authorized by an authenticated user who has access to that data. Every request your application sends to the Google DoubleClick Bid Manager API must include an authorization token. The token also identifies your application to Google.
This is what the error means by
"You are not authorized to use DoubleClick Bid Manager API.
Make sure that you include the following scope when requesting authentication of the user.
More info can be found here and there is documentation here on how to get it working with ruby you will need to alter the example there for your api as this is for calendar.
Note about service accounts.
Service accounts must be pre-authorized in order to work. In the case of Google drive you can take the service account email address and share a folder on your google drive with it. Basically you share data with the service account granting it access to the data. Not all google apis support service account authentication. Youtube api, Doubleclick, and blogger I think addsence or adWords as well, are a few that do not support service account authentication as there is no way to share the data with a user without them responding to the share request.
