For working with Google using 1.0 protocol, applications were required to be registered using https://accounts.google.com/ManageDomains which provided a ConsumerKey and a ConsumerSecret to access feeds.
Newer application registrations are instead done using https://code.google.com/apis/ which provides ClientID, RedirectURL etc. (but not consumer key) as it is based on OAuth 2.0
Question: Is it possible to run an application created with Google APIs (OAuth 2.0) to work with an 1.0a OAuth flow? If yes, what field should be considered as a ConsumerKey?
