Benjamin Deustch enhanced the Adyen/adyen-node-api-library by improving the SDK’s usability and modularity through direct exposure of the SessionAuthenticationAPI from the root index. He reorganized and alphabetized the SDK’s exports, addressing import path inconsistencies and aligning the structure with code review feedback to support future modular enhancements. Working primarily with TypeScript and Node.js, Benjamin focused on API integration and SDK development, ensuring the codebase was more maintainable and accessible for customers. His work established a cleaner, more logical export surface, reducing friction for developers integrating with the SDK and laying a solid foundation for future API surface improvements.
