Hi,
I used google-ads-ruby gem, and I want to get all campaigns and ad_groups under the manager account, what should I do?
I though there were two ways.
One is that I get campaigns directly by manager account. But when i use client.service.google_ads, I got error message: "Request contains an invalid argument."
So I tried another way that is operating sub_account directly. But when I use list_accessible_customers(),and there is not sub_account's resource_name. That means i can't operate the sub_account directly, right?
So, how can I get campaigns from manager account?
