Great systems are built on great APIs.
APIs are the contracts between services, clients, and teams. A badly designed API leads to confusion, bugs, rework, and eventually, broken systems
🔹 Version your APIs: Systems evolve. Prefixing with /api/v1/... ensures you don’t break clients when features change
🔹 Proper methods & idempotency: GET for reads, POST for create. Make retries safe, your future self will thank you.
🔹 Handle errors gracefully: Return meaningful status codes and error bodies...
