API Design and Architecture - Backend Engineering Intro

Learn the fundamentals of API design and architecture in this comprehensive backend engineering tutorial that covers essential concepts for building robust web services. Explore what APIs are and examine different types including SOAP, GraphQL, gRPC, and WebSockets, understanding when and how to use each approach effectively. Master JSON data formatting and discover how to structure API endpoints following RESTful patterns. Dive deep into HTTP methods including GET, POST, PUT, PATCH, and DELETE operations, learning proper implementation techniques for each. Understand the critical differences between nested data structures and filtering approaches, and learn when to use query parameters versus path parameters versus request body data. Examine real-world examples of complete API requests and responses, and master HTTP status codes to provide meaningful feedback to API consumers. Gain practical knowledge through hands-on examples that demonstrate proper API endpoint design patterns and best practices for backend development.
