Strictly speaking, SOAP and REST aren’t directly comparable: REST is an architectural style, and SOAP is a specific protocol defined by a standard. Give the SOAP header and the body. The optional SOAP Fault element is used to indicate error messages. SOAP is a method of transferring messages, or small mounts of information, over the Internet. Well, like any other protocol does, when it’s enforced as the fr anca lingua of a whole ecosystem of services.
Wsdl_headers: custom HTTP headers to be sent on WSDL requests. Soap is recovered from Diversey hotel customers which are Soap for HopeTM program partners, and then transported to a local site where residents reprocess it using an innovative but simple cold-press method.
RESTful web services are stateless. REST services are easy to integrate with existing websites and are exposed with XML so the HTML pages can consume the same with ease. The required SOAP Body element contains the actual SOAP message intended for the ultimate endpoint of the message.
Xml – The entire Soap request (Envelope) including headers. The sequence order of the calls is request, headers and then the dedicated service method. REST opens up lot more client for the exposed WebService than SOAP. REST also requires that the service is adequately documented, whereas a WSDL serves as accurate documentation for any SOAP web service.
XML messages by their self-documenting nature usually have more ‘overhead’ (headers, footers, nested tags, delimiters) than actual data in contrast to earlier protocols where the overhead was usually a relatively small percentage of the overall message.
