When a long API JSON response hides sku, id, trace.id, or order-line fields across unknown nesting levels, format the payload first, use JSONPath recursion and wildcards to discover the field, then verify the stable path with Pointer, key paths, or diff checks.
JSONPath field discovery topic
JSONPath recursive field discovery, wildcard paths, and API response debugging tools
A local workflow for $..field recursive discovery, [*] array wildcards, bracket notation for special keys, and API field lookup.

Common lookup scenarios
Discover nested sku, id, or error-code fields when you do not know the level
Sweep deep item or line arrays with [*] wildcards
Read dotted or hyphenated metadata keys with bracket notation
Explain why an old JSONPath turned empty after a release
Export discovered fields to CSV for QA or ops review
Recommended workflow
- Format the JSON and confirm the root shape
- Use recursive expressions such as $..sku or $..id for field discovery
- Add [*] or a narrower parent path when arrays are deep
- Use ['trace.id'] or ['request-id'] for special keys
- Once stable, verify the final path with Pointer, key paths, or diff checks

LookupToolChakanFAQ
When a long API JSON response hides sku, id, trace.id, or order-line fields across unknown nesting levels, format the payload first, use JSONPath recursion and wildcards to discover the field, then verify the stable path with Pointer, key paths, or diff checks.
When should I start with recursive JSONPath?
Start with recursion when you know the field name but not the nesting level. After discovery, narrow it to a more stable path.
Why combine this with Pointer or key paths?
Recursive lookup is best for discovery. Fixed paths are better for docs, tests, and post-release regression checks.
