SOAP (Simple Object Access Protocol) and REST (Representational State Transfer) are both web service communication protocols. SOAP was long the standard approach to web service interfaces, although it’s been dominated by REST in recent years, with REST now representing more than 70% of public APIs, according to Hunsaker (2015).
REST Operates through a solitary, consistent interface to access named resources. It’s most commonly used when you’re exposing a public API over the Internet. SOAP, on the other hand, exposes components of application logic as services rather than data. Additionally, it operates through different interfaces. To put it simply, REST accesses data while SOAP performs operations through a more standardized set of messaging patterns. Still, in most cases, either REST or SOAP could be used to achieve the same outcome (and both are infinitely scalable), with some differences in how you’d configure it. In addition to using HTTP for simplicity, REST offers a number of other benefits over SOAP: REST allows a greater variety of data formats, whereas SOAP only allows XML. Coupled with JSON (which typically works better with data and offers faster parsing), REST is generally considered easier to work with. Thanks to JSON, REST offers better support for browser clients. REST provides superior performance, particularly through caching for information that’s not altered and not dynamic. (Kumuri et al 2015). It is the protocol used most often for major services such as Yahoo, Ebay, Amazon, and even Google. REST is generally faster and uses less bandwidth. It’s also easier to integrate with existing websites with no need to refactor site infrastructure. This enables developers to work faster rather than spend time rewriting a site from scratch. Instead, they can simply add additional functionality. Still, SOAP remains the preferred protocol for certain use cases. The general consensus among experts these days is that REST is the typically preferred protocol unless there’s a compelling reason to use SOAP (and there are some cases in which SOAP is preferred).
SOAP was originally created by Microsoft, and it’s been around a lot longer than REST. This gives it the advantage of being an established, legacy protocol. But REST has been around for a good time now as well. Plus, it entered the scene as a way to access web services in a much simpler way than possible with SOAP by using HTTP. There are some use cases that SOAP tends to be better-suited for. For instance, if you need more robust security, SOAP’s support for WS-Security can come in handy. It offers some additional assurances for data privacy and integrity. It also provides support for identity verification through intermediaries rather than just point-to-point, as provided by SSL (which is supported by both SOAP and REST). Another advantage of SOAP is that it offers built-in retry logic to compensate for failed communications. REST, on the other hand, doesn’t have a built-in messaging system. If a communication fails, the client has to deal with it by retrying. There’s also no standard set of rules for REST. This means that both parties (the service and the consumer) need to understand both content and context.
At the end of the day, the best protocol is the one that makes the most sense for the organization, the types of clients that you need to support, and what you need in terms of flexibility. According to Hunsaker (2015), most new APIs are built using REST and JSON, simply because it typically consumes less bandwidth and is easier to understand.
