HTTP API
An HTTP API (Application Programming Interface) is a set of rules and protocols that allows different software applications to communicate over the HTTP protocol, typically using methods like GET, POST, PUT, and DELETE to perform operations on resources. It enables data exchange between clients (e.g., web browsers, mobile apps) and servers in a standardized way, often returning data in formats like JSON or XML. This concept underpins modern web services, microservices architectures, and integrations between distributed systems.
Developers should learn HTTP APIs because they are fundamental for building web applications, mobile backends, and cloud services, enabling interoperability across platforms and technologies. They are essential for implementing RESTful services, handling CRUD operations, and integrating third-party services like payment gateways or social media platforms. Understanding HTTP APIs is crucial for roles involving backend development, API design, or DevOps, as they form the backbone of most client-server interactions on the internet.
