Mess with MSN Messenger have just posted their findings of a new add-in API in the leaked build 683 of Windows Live Messenger. It is reportedly labeled Messenger Client Side Plug-ins Type Library.
This new library will allow developers to create their own add-ins for Windows Live Messenger, which will be officially documented and supported, much like the limited activity API.
I just refreshed and timothy has posted a more definite list of members of the type library. It still looks quite limited, but it is a start. Many users have been waiting a long time for something like this! I know I have.
Finally!!! It does look rather limited, but at least its progress
Daniel, you forgot an f in your href (feel free to delete this comment).
Oopsie, my HTML proof reading skills aren’t so good
With the API of MSN Messenger 7.5 i always have problems they work at some people and there isnt an explonation why dont dont work with some people. Hope this one hasnt.
The other API is pretty much unsupported and those problems are common. Since this new one is exclusive to WLM and not in Windows Messenger as well, it should be fine. They are also taking this one seriously (or so it seems).
nice… its a shame it leaked though, someone needs a kick in the pants
