Why use API Response Analyzer?
Production APIs fail in subtle ways: wrong Content-Type, slow TLS, or a 200 with an error object in JSON. This analyzer performs a GET from the browser, records timing and headers, and highlights parsing issues so you can spot regressions before customers do.
Practical tips
- Test both the apex URL and any CDN or API-gateway hostname you expose publicly.
- If JSON parsing fails, fetch the raw body with REST Endpoint Tester to inspect encoding.
- Watch for cache headers: stale CDN responses often look like application bugs.
Common questions
- Why might latency differ from curl?
- Browsers add TLS negotiation, connection limits, and extension overhead. Use multiple samples and compare trends, not single numbers.
- Can I analyze POST APIs here?
- This page focuses on GET health checks. Use REST Endpoint Tester for methods with a body or custom headers.
