What is an API? Types of APIs Explained | System Design | 6

APIs are the backbone of modern applications, but what exactly are they, and why do we need them? In this video, we break down APIs from a System Design perspective — starting from the understanding APIs, to understanding its types. You’ll learn: • Why APIs are needed in modern development • How frontend, backend, and different services communicate We also cover different types of APIs: • REST (JSON-based, most commonly used) • SOAP (XML-based, legacy but still used in enterprises) • GraphQL (flexible data fetching) • gRPC (high-performance communication) • WebSockets (real-time communication) Whether you're preparing for interviews or trying to understand real-world systems, this video will give you a solid foundation.
