Web APIs
Web APIs (Application Programming Interfaces) are interfaces that allow different software applications to communicate over the web using standard protocols like HTTP/HTTPS. They define a set of rules and specifications for how requests and responses should be structured, typically using formats such as JSON or XML. Web APIs enable the integration of services, data exchange between systems, and the building of distributed applications like web and mobile apps.
Developers should learn Web APIs to build modern, interconnected applications that leverage external services, share data across platforms, and create scalable architectures. They are essential for implementing features like third-party integrations (e.g., payment gateways, social media logins), microservices communication, and developing RESTful or GraphQL-based backends. Mastery of Web APIs is crucial for full-stack development, cloud computing, and IoT projects where seamless data flow is required.
