How can I retrieve contacts/emails from things like MSN, Twitter, Facebook, GMail , etc...?

Question

Hi,

I'm building an application that gives users the option to send out an email notification to their friends.

The options I would like to give them for this are to:

• manually write down which emails they would like to send to
• choose contacts from a list of ones already in the database for that user
• choose all contacts from facebook, twitter, digg, gmail, or msn to send the email to

Is there any way I can retrieve all of the email addresses for a certain contact from these different websites?

For example, if I chose the option to send out email notification and I wanted to send it to all of my friends on my facebook account, how could I do this? (Remembering that the user is interacting with a completely separate website and should not have to go onto facebook to send this emails)

Any ideas?

Thanks in advance for your help!

Matt

Answer 1

For each websites (twitter, facebook, etc.) use their API for accessing contacts.

Answer 2

Google contacts api: http://code.google.com/apis/contacts/ Windows Live contacts api: http://msdn.microsoft.com/en-us/library/bb463989.aspx

Facebook's apis are here: http://wiki.developers.facebook.com/index.php/API

Answer 3

Russau was faster with the Google contacts API. For sending Gmail messges there is also a third-party API here. Actually I thought that also Google released one, but I couldn't find it at the moment.

\Edit: This might be relevant too.
