What kind of authorization I should use for my Django facebook app

I am building a facebook application using Django where I am using Google Data API (Blogger API) to read website's content.

So, what kind of authorization I should use in Google Data API to read the website.. To be specific, what kind of OAuth authorization I should use and how? 

(I want my users to use my app without any login credentials)..

Can anyone help me on it?
