If you wish to create a client session key you will need to call the CreateSessionKey method. This method is available to developers from the Users.asmx Web Service and is the first step when using the My Alerts web service. The CreateSessionKey method must be called to retrieve the ClientId and SessionKey which are required in all calls to the My Alerts Web Services. This function is automatically called by the iShare portal.
