API DESIGN ROADMAP FOUNDATIONS What is an API → Interface that allows systems to communicate Types of APIs → REST, GraphQL, SOAP, gRPC HTTP Basics → Methods (GET, POST, PUT, DELETE), Status Codes Client-Server Architecture → Separation of concerns JSON & Data Formats → JSON, XML, Protocol Buffers REST API DESIGN REST Principles → Statelessness, Uniform Interface Resource Naming → Use nouns, not verbs (e.g., /users, /orders) HTTP Methods → → GET → Retrieve data → POST → Create data → PUT/PATCH → Update data → DELETE → Remove data Status Codes → 200, 201, 400, 401, 404, 500 Versioning → /v1/users, /v2/users API STRUCTURE & BEST PRACTICES Consistency → Use standard naming conventions Pagination → Limit large datasets (?page=1&limit=10) Filtering & Sorting → Query parameters (?sort=asc) Error Handling → Clear, structured error responses Idempotency → Same request → same result Rate Limiting → Prevent abuse (e.g., 100 requests/min) AUTHENTICATION & AUTHORIZATION Authentication → Verify user identity → API Keys → OAuth 2.0 → JWT (JSON Web Tokens) Authorization → Control access levels (roles & permissions) Secure Endpoints → Protect sensitive routes API SECURITY HTTPS → Encrypt communication Input Validation → Prevent malicious data CORS → Control cross-origin requests Rate Limiting → Prevent DDoS attacks Data Sanitization → Avoid injection attacks Secrets Management → Secure API keys & tokens DOCUMENTATION OpenAPI / Swagger → Standard API documentation Postman → API testing & documentation Clear Examples → Request & response samples Endpoint Descriptions → Explain purpose & usage Version Documentation → Track API changes TESTING Unit Testing → Test individual components Integration Testing → Test full API flow Automated Testing → CI/CD pipelines Load Testing → Handle high traffic Tools → Postman, Jest, Mocha, Supertest PERFORMANCE & SCALABILITY Caching → Redis, CDN Database Optimization → Indexing, query tuning Load Balancing → Distribute traffic Async Processing → Queues (RabbitMQ, Kafka) Horizontal Scaling → Add more servers ADVANCED CONCEPTS GraphQL → Flexible querying gRPC → High-performance communication WebSockets → Real-time APIs API Gateway → Centralized API management Microservices → Break into smaller services DEVOPS & DEPLOYMENT CI/CD → Automate testing and deployment Docker → Containerize APIs Kubernetes → Orchestrate services Monitoring → Logs, metrics (Prometheus, Grafana) Cloud Deployment → AWS, Azure, GCP REAL-WORLD BEST PRACTICES Design First → Plan before coding Backward Compatibility → Avoid breaking changes Logging → Track API usage and errors Throttling → Control traffic spikes User Experience → Simple, predictable APIs FINAL LEARNING PATH Learn HTTP & REST → Understand the basics Build Simple APIs → CRUD operations Add Authentication → Secure your API Document Properly → Use Swagger/Postman Optimize Performance → Scaling & caching Deploy to Cloud → Production-ready APIs Grab the API DESIGN EBOOK: codewithdhanian.gumroad.com/l/nbfkk

Foreclosure filings hit 38,840 in Feb — up 20% YoY. Most of those sellers have mortgages from 2020-2022 at 2-3%. New buyers paying 6.25%. That gap IS the sub-to opportunity. Stop wholesaling all your deals. Some of these need to be kept. 🏠
