Mastering scalable APIs using System Design
Designing APIs is akin to assembling a puzzle, requiring careful planning for seamless system communication. APIs, essential in modern software development, enable interoperability, modularity, and scalability. Key types include RESTful APIs, which emphasize statelessness and resource-based design; GraphQL APIs, allowing flexible data queries; and SOAP APIs, which use XML for structured communication. Status codes categorize responses, indicating success or errors. Benefits of APIs include decoupling services, facilitating integration, and promoting reusability. Adhering to best practices in API design—such as clear documentation, versioning, and security—ensures robust applications that meet evolving needs in today’s digital landscape.
