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

Generate an OpenAPI 3.1 specification from existing code by running the spec generation workflow against your codebase. This code-first approach automatically produces a complete and validated contract for your RESTful API.

What is the difference between design-first and code-first OpenAPI workflows?▼

Design-first OpenAPI workflows draft the specification before writing implementation code, while code-first workflows generate the API documentation from existing source code. This Skill supports maintaining and validating contracts across both approaches.

Can I validate my API implementation against an OpenAPI contract?▼

Yes, you can validate implementations against OpenAPI contracts. This ensures your RESTful API endpoints conform to the defined structure, maintaining contract consistency and verifying SDK readiness across new and existing APIs.

Does this OpenAPI generation approach support client SDK generation?▼

Yes, the OpenAPI spec generation process supports client SDK generation. By creating and validating structured OpenAPI 3.1 specifications with reusable components, it ensures your API contract is fully ready for automated SDK creation.

How do I maintain versioned OpenAPI specs and documentation portals?▼

Maintain versioned OpenAPI specs and set up documentation portals by applying the provided generation and validation patterns. This ensures structured API documentation remains consistent and synchronized across new and existing API versions.
