The OpenAPI Initiative has announced the release of OpenAPI 3.1, which introduces multiple new functionalities and improvements compared to its predecessors. APIMatic, a solution provider for API management, has announced that it supports OpenAPI 3.1 as one of its latest supported API specification formats, enabling users to transform their existing API definitions into OAS 3.1 or generate API portals and SDKs in various programming languages using the APIMatic Code Generator and Docs Generator. The APIMatic Transformer tool maps components from OpenAPI 3.0 to OpenAPI 3.1, including the Schema Object, Info Object, Components Object, Responses, Parameters, RequestBodies, and other components, addressing differences such as nullable flags, exclusive minimum and maximum values, single-valued enums, file uploads, and reference objects. The tool also supports multiple examples and updates in OpenAPI 3.1, allowing users to transform their existing OpenAPI 3.0 files to the latest format with minimal effort using APIMatic's transformation capabilities.
