Start by systematically inspecting each failing request's method, URL, headers, and body against the API documentation, then isolate and fix issues one at a time while verifying each fix with a test call. After all individual requests pass, run the full sequence end-to-end to catch any state or dependency issues.
Pro tip: Demonstrate production maturity by checking for idempotency and rate limiting early, and always capture the full error response body and headers—not just the status code—to pinpoint the root cause quickly.
Re-run each failing request individually and log the full HTTP response (status, headers, body) to understand the exact error messages and codes.
Compare the request's method, URL, query params, headers (auth, content-type), and body schema with the API documentation to spot mismatches.
Apply the minimal correction for each issue (e.g., add missing auth header, correct JSON field) and re-run that single request to confirm it now returns 2xx.
Execute all five requests in order to ensure no state dependencies or side effects break the sequence, and that the entire flow passes.
Summarize what was wrong with each request and suggest improvements like better error handling, validation, or logging to avoid similar issues.
