Getting The Most Out of Messenger

Let web site visitors interact with Windows Live Messenger users using the Windows Live Messenger Library, Windows Live Messenger IM Control, and the Windows Live Presence API.  You can also use the Windows Live Messenger client, version 7.0 and later, to develop a single-user or multi-user application through the Windows Live Messenger Activity API.

 

 

IM Control

The IM Control enables web sites to show the presence of Windows Live Messenger users and let site visitors engage in IM conversations with site owners or representatives.

Presence API

The Presence API is an HTTP-based API that returns a Windows Live Messenger user's presence.

Messenger Library
