REST API
REST (Representational State Transfer) API is an architectural style for designing networked applications, using HTTP protocols to enable communication between clients and servers. It relies on stateless operations, standard HTTP methods (GET, POST, PUT, DELETE), and resource-based URLs to create scalable and interoperable web services. APIs following REST principles allow systems to exchange data in formats like JSON or XML, making them foundational for modern web and mobile applications.
Developers should learn REST API design to build scalable, maintainable, and interoperable web services that integrate with diverse clients, such as web apps, mobile apps, and IoT devices. It is essential for creating microservices architectures, enabling third-party integrations, and supporting data exchange in cloud-based applications, as it simplifies client-server communication using widely adopted HTTP standards.
