How to use JSON Patch & Pointer
Enter a JSON Pointer expression (RFC 6901) to navigate to a specific value inside a document, or define a JSON Patch (RFC 6902) operation set — add, remove, replace, copy, move — to apply targeted mutations to a JSON document.
Common use cases
API designers use this to describe precise incremental updates in PATCH endpoints without sending full replacement bodies. Backend developers use it to test and validate patch operation sequences during development, and tooling authors use it to generate patch sets for configuration management.
