API Debugging Tools

This page targets practical API debugging workflows: validate malformed payloads, inspect JWT claims, compare version changes, and convert event timestamps.

Debugging checklist for API teams

1) Validate payload syntax with JSON Validator. 2) Normalize output with JSON Formatter. 3) Inspect auth claims with JWT Decoder. 4) Compare revisions with Diff Checker.

Time and auth troubleshooting

Many API incidents are caused by token expiry and timezone mismatches. Use Timestamp Converter together with JWT decoding for faster root-cause analysis.
