Which tool is mentioned for converting RAML data types to OpenAPI (OAS) data types?

• A. apimatic.io
• B. SwaggerHub
• C. Postman
• D. OpenAPI Generator

Answer: (A)

Converting RAML data types to OpenAPI data types requires a tool that translates API description formats, mapping RAML schema types to OpenAPI schema types. apimatic.io is designed for this kind of transformation, offering RAML to OpenAPI conversion so you can generate a valid OpenAPI specification from a RAML model and then use it for further tooling or SDK generation. The other options focus more on design, collaboration, testing, or code generation from OpenAPI rather than performing a direct RAML-to-OpenAPI conversion. SwaggerHub centers on designing and hosting API specs (OpenAPI and RAML), Postman handles API testing and import workflows, and OpenAPI Generator builds code from OpenAPI, not convert RAML to OpenAPI. That's why apimatic.io is the best choice for this task.
