FAQPage Schema

How do I generate an OpenAPI 3.1 specification from existing source code?▼

To generate an OpenAPI 3.1 specification from source code, provide your API code or annotations to run a code-first generation workflow, producing a synced API spec document.

What is the best way to keep my API documentation in sync with code changes?▼

Keeping API documentation in sync involves validating and linting your OpenAPI spec against the source code, ensuring contract compliance and preventing integration gaps caused by outdated designs.

Can I validate a design-first OpenAPI schema against my RESTful API implementation?▼

Yes, you can validate a design-first OpenAPI schema by running consistency checks and linting against your RESTful API implementation patterns to ensure full contract compliance.

How do I prepare an API documentation portal and SDK from an OpenAPI spec?▼

You prepare an API documentation portal and SDK by applying template-driven generation to your OpenAPI spec, producing formatted documentation and SDK code outputs.

Why does my OpenAPI specification keep going out of sync with my API design?▼

OpenAPI specifications go out of sync when documentation is maintained separately from the code, a problem solved by using code-first generation or enforcing validation patterns.
