I wish to write an API that can get the contacts list from Gmail, Yahoo and other e-mails. How can this be done? Are there already existing APIs for them or do I need to write PHP code to extract information?
I need a referral system like DropBox has. Has anyone coded it themselves or is it available as open source?

Please guide me in this regard. Any link or explanation will do the job.
Thanks 🙂
Google has an API: http://code.google.com/intl/en/apis/contacts/
And Yahoo also has an API: http://developer.yahoo.com/social/contacts/
There exists some other which are mentioned in this thread: PHP APIs for Hotmail, Gmail and Yahoo?
