The debate between REST/JSON and SOAP/XML has been going on for years, but it takes on new nuances when you look at it through the lens of mobile web services. That is why we decided to dig into the topic and compile the key differences into a handy infographic.
REST (Representational State Transfer) is an architectural style that typically uses JSON to format request and response messages, while SOAP (Simple Object Access Protocol) is a messaging protocol that relies on XML. Both JSON and SOAP are used across different mobile platforms, and each format has its own strengths depending on the criteria you care about most. The comparison below looks at REST vs. XML and JSON vs. SOAP from three angles: the speed of performance, the size of request and response messages, and the ease of consumption for developers building mobile and web applications.
In short, JSON and RESTful web services tend to be lighter and faster to parse, which makes them a popular choice for mobile apps where bandwidth and speed matter. SOAP with XML, on the other hand, offers stricter standards and built-in error handling, which can be useful for more complex enterprise integrations. Choosing between REST API vs. JSON API approaches (or, more precisely, between JSON and SOAP as messaging formats) usually comes down to the specific requirements of your project rather than one format being universally better than the other.
Understanding the difference between REST vs. XML and JSON vs. SOAP is also useful when working with eCommerce APIs, since the way a platform is built affects how easily it can be integrated.
