JSON Pointer
JSON Pointer is a standardized string syntax for identifying a specific value within a JSON document.
The Design of Web APIs, Second Edition
JSON Pointer is a standardized string syntax for identifying a specific value within a JSON document.
- How it is used
- Uses standardized document locations to reuse OpenAPI components, identify request errors, and target linter overrides.
- How deep it goes
- Explains root markers, slash-separated properties, reuse, and slash escaping, but does not develop the full standard grammar.
- Examples
- Demonstrates Product schema references, request-body error locations, and a Spectral override for an accounts endpoint.
- What you can do after
- Apply JSON Pointer to configure reusable OpenAPI references, locate API errors, and suppress selected Spectral findings.

Automating API Delivery
JSON Pointer is a string syntax for identifying a specific value within a JSON document.
- How it is used
- Targets individual OpenAPI objects when Spectral linting rules need project- or operation-specific overrides.
- How deep it goes
- Defines document-value identification and demonstrates percent-encoded operation paths, but defers general syntax details to an appendix.
- Examples
- Uses PUT and DELETE operations under /users/{id} to demonstrate disabling and warning-level operationId rules.
- What you can do after
- Operate Spectral with overrides that selectively disable or downgrade rules for named OpenAPI operations.
