APIs are not just code; they are products that must evolve safely. In this video, we break down the API Lifecycle as a disciplined engineering process—covering everything from the initial design contract to final deprecation. Whether you are a backend developer, system architect, or software engineering student, understanding the full lifecycle of an API is crucial for building scalable and maintainable systems. 🚀 IN THIS VIDEO, YOU WILL LEARN: 📚 API Design: How to define contracts using OpenAPI and model resources. 📚 Development & Testing: Best practices for stateless services, idempotency, and contract testing. 📚 Deployment Strategies: Using CI/CD pipelines, containerization, and Blue-Green/Canary deployments. 📚 Versioning: Managing backward compatibility and breaking changes safely. 📚 Deprecation: How to retire legacy endpoints without disrupting clients.
