Statelessness: Each client request should contain all of the information needed to complete the request, and the server should not keep any state information about the client between requests.Ĭacheability: Depending on the system’s requirements, responses should be cacheable or non-cacheable. The following are the fundamental principles of RESTful architecture:Ĭlient-Server Architecture: The client and server should be independent and communicate using a standardized protocol (such as HTTP). Understanding the Basics of REST Architecture RESTful service principles encourage loose coupling across systems, making it easy to modify and update services without disturbing the overall system. RESTful services conduct CRUD (Create, Read, Update, Delete) actions on resources that can be represented in many formats such as JSON, XML, or plain text using HTTP methods such as GET, POST, PUT, and DELETE. RESTful services standardize how web-based systems interact with one another, enabling more efficient and scalable data transmission. REST (Representational State Transfer) is a set of architectural principles for developing web services that exchange data across applications. HTTP is a client-server protocol, which means that a client application (such as a web browser) sends a request to a server application, and the server answers with the information requested. HTTP (Hypertext Transfer Protocol) is the foundation of the World Wide Web, allowing web-based applications to communicate with one another. Introduction to HTTP and RESTful Services

In this article, we’ll go over the fundamentals of HTTP and RESTful services, as well as show how to utilize Postman to develop and consume RESTful APIs. Postman, a popular API testing tool, has made testing and interacting with RESTful services easier than ever. HTTP and RESTful web services have transformed the way programs communicate over the internet.
