FAQPage Schema
How do I generate OpenAPI 3.1 specifications from existing code?

You can generate OpenAPI 3.1 specifications from existing code using a code-first workflow. This approach automatically derives API documentation, schemas, and security schemes directly from your codebase to ensure production-ready specs.

What is the best way to validate API contract compliance across services?

Validating API contract compliance is best handled by enforcing OpenAPI structure against design-first specs or validation patterns. This ensures consistency and interoperability across services by checking templates, schemas, and examples.

Can I use a design-first approach to create OpenAPI documents for SDK generation?

Yes, you can use a design-first approach to create OpenAPI documents for SDK generation. The workflow supports defining templates, schemas, and security schemes upfront to drive consistent client SDK generation and API documentation.

Does OpenAPI spec generation support hybrid workflows for API documentation?

OpenAPI spec generation fully supports hybrid workflows for API documentation. It combines design-first and code-first approaches, allowing you to maintain consistent OpenAPI documents even when mixing design artifacts with codebase inputs.

When do I need to enforce OpenAPI structure for my API specs?

You need to enforce OpenAPI structure when creating API docs portals, generating SDKs, or ensuring API contract compliance. It validates your templates, schemas, examples, and security schemes to deliver consistent, production-ready specs.
