SOAP often uses HTTP as the transfer mechanism. REST provides an excellent caching infrastructure over HTTP GET methods and enables developers to mark response data as cacheable or non-cachable. The goal of caching is never having to generate the same response twice, which helps gain speed and reduce server load. ![]() Related: What Is A Web Application? Definition And How It Works Caching benefit with REST API calls A SOAP API uses more bandwidth, which may affect systems that handle a lot of data. Compared to a REST request, a SOAP request contains more information. Developers primarily use REST for web services, as its lightweight nature is helpful in these situations. Related: Cyber Security Interview Questions And Answers SOAP requires more bandwidth compared to RESTÄ«ecause of the envelope-style of payload transmission, SOAP has a little additional overhead by default. ![]() While SOAP and REST APIs can encrypt their communication using HTTPS and SSL, SOAP provides an additional layer of WSS on the message level, ensuring that only the allowed server process can read it. REST can use the secure version of the hypertext transfer protocol (HTTP), hypertext transfer protocol secure (HTTPS) and both support SSL for end-to-end security. SOAP offers web services security (WSS), superior to secure sockets layer (SSL) in transport security and better suited for integration with enterprise-level security technologies. Related: Database Interview Questions For Freshers And Experienced Professionals (With Sample Answers) REST and SOAP handle security differently While JSON is the most commonly used format, REST APIs can also accept XML, plain text and XML. The format of the SOAP envelope includes header and body, whereas REST APIs are format neutral. REST supports various data formats, including plain text, HTML, extensible markup language (XML) and JavaScript object notation (JSON), making it a better fit for data and increasing browser compatibility, whereas SOAP only supports XML. REST is a more data-driven architecture, whereas SOAP is a standardised protocol for sharing structured data that is more function-driven. Related: Essential Web API Interview Questions And Example Answers REST APIs access a resource, whereas SOAP APIs perform an operation Instead, a REST API exposes the uniform resource locator (URL) for users and a post request to that URL creates a user. A SOAP API that exposes functionality to create a user, for example, might include a function called CreateUser in the SOAP body. ![]() You develop REST APIs after the data, whereas you can create SOAP APIs after the API's functionality. SOAP employs a service interface to expose specific portions of an application's business logic on a server, whereas REST uses uniform resource identifiers (URIs) to do the same. Here are some key differences between them: SOAP is a protocol, whereas REST is an architectural style Though both are API formats for accessing web services, both have some pros and cons. REST versus SOAP is an important decision developers make when creating application programming interfaces. In this article, we discuss the fundamental difference between REST and SOAP with examples, explore their advantages and outline some popular alternatives. If you plan to build a program that depends on web services, knowing the difference between REST and SOAP can help you decide the suitable API for your project. Both REST and SOAP (simple object access protocol) connect two applications via server-side data that are machine and human-readable. Representational state transfer (REST) has become the preferred choice for public application programming interfaces (APIs) and open-source work that allows other developers to connect and efficiently use the data.
