Explaining what is an API (Application Programming Interface)

Skip the simplified analogies. Well except for the serveur haha MAIS this video dives straight into the technical mechanics of Application Programming Interfaces (APIs), explaining the exact data structures, protocols, and architectural patterns that allow distributed systems to communicate securely and efficiently. We break down the lifecycle of an API call from the client application to the server and database, exploring the anatomy of HTTP requests, authentication flows, and response payloads. What you will learn in this video: The Request/Response Cycle: How clients construct HTTP requests (GET, POST, PUT, DELETE) and target specific server endpoints. Authentication: The role of Headers and Bearer tokens in securing data transmission. Data Payloads: Parsing syntax-highlighted JSON responses and understanding HTTP status codes (e.g., 200 OK, 404 Not Found, 500 Internal Server Error). REST vs. WebSockets: The transition from stateless, individual HTTP requests to persistent, bi-directional, real-time data streams. Video 1 out of 2 tho
