Introduction “SOAP is a Remote Procedure Calling protocol that works over HTTP. The body of the request is in XML. A procedure executes on the server and the value it returns is also formatted in XML. Procedure parameters and returned values can be scalars, numbers, strings, dates, etc. ; and can also be complex record and list structures. ” (- A Busy Developer’s Guide To Soap 1. 1) 2/6/2022 3
