Basic usage instructions

Fetch users’ contact lists from your web application without asking them to provide their passwords.

First, register your application’s domain. Then make users follow this URL:

  Contacts::Google.authentication_url('http://mysite.com/invite')

They will authenticate on Google and it will send them back to the URL provided. Google will add a token GET parameter to the query part of the URL. Use that token in the next step:

  gmail = Contacts::Google.new('example@gmail.com', params[:token])
  contacts = gmail.contacts
  #-> [ ['Fitzgerald', 'fubar@gmail.com', 'fubar@example.com'],
        ['William Paginate', 'will.paginate@gmail.com'], ...
        ]

Read more in Contacts::Google. I plan to support more APIs (Microsoft Live, for starters); feel free to contribute.
