FAQPage Schema

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

To generate an OpenAPI 3.1 specification, you describe your REST API endpoints, data models, and validation rules. The tool processes source code, annotations, or design artifacts to produce structured API schemas.

What is design-first API development and how does it keep SDKs in sync?▼

Design-first API development uses OpenAPI 3.1 specifications as the source of truth, enabling contract validation and automated SDK generation. This ensures client portals and documentation remain synchronized with runtime behavior.

Can I use OpenAPI specs for contract testing in automated pipelines?▼

Yes, you can use OpenAPI specs for contract testing within automated test pipelines. The tool validates structured schemas and validation rules against code, tests, and runtime behavior across RESTful services.

How do I validate my API documentation against runtime behavior?▼

You validate API documentation by comparing your OpenAPI 3.1 specification against code, tests, and runtime behavior. This ensures your API contracts, structured schemas, and validation rules are accurate and up-to-date.

Does this approach work for configuring API gateways across RESTful services?▼

Yes, generating OpenAPI 3.1 specifications applies to API gateway configurations across RESTful services. It enforces structured schemas and validation rules to maintain accurate API contracts and integration with codebases.
