The error says that there is a mandatory parameter by the name "Key" which you are not providing while calling the webservice. Please test the webservice via some other tool like Altova xmlspy.

Take the message sent from xi to webservice and use xmlspy to call the webservice using the same message. xmlspy will give you much clearer picture.
