Hi Saba,

The web services are not officially documented as they weren't originally intended for general public consumtion but rather glue various K2 integration components together.  If your not currently aware, the major APIs (K2ROM, K2Mng, KO and K2Studio are all well documented in the help file.

 CanIConnect is a very basic method that simply immediately returns true:
public bool CanIConnect()
{
     return true;
}

This is just a quick test to ensure the InfoPath user is able to see the webservice.  Feel free to post other web services questions as well.
