Worked on enhancing organization management APIs in the logto-io/logto repository, focusing on improving reliability and developer experience. Developed new response bodies for organization user endpoints, specifically for adding users and assigning roles, ensuring that clients receive consistent and relevant data after these operations. Updated API documentation to reflect the new response payloads and reorganized unit tests into dedicated files to improve test coverage and maintainability. Utilized TypeScript for implementation and unit testing, emphasizing API predictability and smoother client integration. These changes support faster onboarding for partners and strengthen the robustness of internal services by making API interactions more transparent.
