My ideal v3 directory client.

example.rb

##### In my app
class Account <  DirectoryClient::Base
  def self.specific_convenient_scope_method
    where(blah: "blah").order(:bloo)
  end
end

Account.all
# Handles OAuth authentication and reauthentication on timeout
# Introspects class name to work out api endpoint (/api/v3/accounts)

#### In client
class DirectoryClient::Base
  # OAuth handling
  # Ransack compatibile methods
end

# In short, the client is skinny and, like the API v3 BaseController, implements a generic class that has 
# all the non unique functionality of every API endpoint baked in. It is then up to the dev to extend
# or include that class in their actual endpoint specific classes.

# Best of both worlds. Client isn't updated every time theres a new endpoint, but abstract away authentication
# into the bowels of the client.
