The latest update of APIMatic, version 3, aims to enhance developer experience and simplify API management for organizations going digital. The Code Generator has been overhauled with new features and improvements, including updated language versions, dependencies, and adherence to coding standards, as well as support for immutable clients, timeouts, and retries on API call errors. Additionally, the API Portal has been revamped with a more aesthetic and interactive interface, featuring a Markdown docs editor, pop-out code samples, and version-specific documentation. The API Transformer now supports anyOf, oneOf, not constructs, and union types, making it easier to polish API definitions. The update ensures backward compatibility during migration and preserves existing data.
