SOAP (originally Simple Object Access Protocol) is a messaging protocol specification for exchanging structured information in the implementation of web services in computer networks Its purpose is to induce extensibility , neutrality and independence. For most ’s servers, RESTful web services provide a good caching infrastructure over an HTTP GET method. Set the request method to POST. Creating clients, developing APIs, the documentation is much easier to understand and there aren’t very many things that REST doesn’t do easier than SOAP.
Service producers and consumers must understand the context and content being passed along as there is no standard set of rules to describe the REST web services interface. In case of transactional work SOAP web services needs to be used where on other hand REST web services provides simplicity.
The SOAP specification defines the structure of the SOAP messages, not how they are exchanged. These different services, especially UDDI, have proved to be of far less interest, but an appreciation of them gives a complete understanding of the expected role of SOAP compared to how web services have actually evolved.
Instead they can expose and access web services using technology already deployed. Juste a note to avoid wasting time on php-soap protocol and format support. NormalizeNames: if your wsdl operations contains names with non identifier characters (^a-z$_0-9), replace them with _. Note: if using this option, clients using wsdls with two operations like soap:method and soap-method will be overwritten.
SOAP relies on building XML-based systems, which means the amount of data is inherently larger, which in turn means it’ll cost you a lot more for central processing unit (CPU) and memory usage, usually to the point that you have to build custom servers to handle the load.
