![]() ![]() Stateful operations – if the application has a requirement that the state needs to be maintained from one request to another, then the SOAP 1.2 standard provides the WS* structure to support such requirements.If such a scenario exists then, it's always better to use the SOAP protocol. There can be a firm agreement that the web service will only accept the cart item name, unit price, and quantity. Let's assume we have a web service that does the final payment. An example is an online purchasing site in which users add items to a cart before the payment is made. A Formal means of communication – if both the client and server have an agreement on the exchange format then SOAP 1.2 gives the rigid specifications for this type of interaction.Asynchronous processing and subsequent invocation – if there is a requirement that the client needs a guaranteed level of reliability and security then the new SOAP standard of SOAP 1.2 provides a lot of additional features, especially when it comes to security.Let's list Difference Between SOAP vs REST Web Services However, we can find how REST differs from SOAP. If done right, there's less coupling, and changes can be dealt with more gracefully. You don't violate the protocol standards by creating extra methods, you leverage on the standard methods and create the actions with them on your media type. For example, consider an application with employee data that other applications can manipulate. The SOAP API exposes functions or operations, while REST APIs are data-driven. This creates significant differences in how SOAP APIs and REST APIs behave. It's a generic client that knows how to use a protocol and standardized methods, and an application has to fit inside that. SOAP is a protocol, while REST is an architectural style. You need constant updates following any change, but it's easier to ascertain if the contract is being followed.Ī REST client is more like a browser. There's a rigid contract between client and server, and everything is expected to break if either side changes anything. This is probably one of the sources of confusion around it since people tend to call REST any HTTP API that isn't SOAP.Ī SOAP client works like a custom desktop application, tightly coupled to the server. SOAP and REST can't be compared directly since the first is a protocol (or at least tries to be) and the second is an architectural style. ![]() Unfortunately, there are a lot of misinformation and misconceptions around REST.
