'''SOAP''', originally an acronym for Simple Object Access Protocol,{{efn|Since version 1.2 of the specification it is no longer an [[acronym]] for Simple Object Access Protocol}} is a messaging [[protocol (computing)|protocol]] specification for exchanging structured information in the implementation of [[web service]]s in [[computer network]]s. It uses [[XML Information Set]] for its [[message format]], and relies on [[application layer]] protocols, most often [[Hypertext Transfer Protocol]] (HTTP), although some legacy systems communicate over [[Simple Mail Transfer Protocol]] (SMTP), for message negotiation and transmission.
