When an API call fails, the immediate reaction is often to check the status code. While essential, a 4xx or 5xx response is merely a symptom. True debugging involves dissecting the entire request-response lifecycle, methodically tracing the flow to identify the root cause. This isn't about guessing; it's about a systematic, engineering-driven approach to pinpoint exactly where the contract broke down. Deconstructing API Failures: A Hands-On Debugging Checklist Effective API debugging demands more than just inspecting logs; it requires understanding the common failure points and systematically validating each stage. Here's a practical checklist to guide your investigation. Phase 1: Inbound...
