Worked on stabilizing the Synchronization feature in the contentstack/contentstack-typescript repository by correcting the API endpoint to use /stacks/sync and standardizing parameter handling. This involved updating TypeScript code to ensure consistent parameter passing and aligning unit tests with the revised endpoint structure. Focused on API integration and bug fixing, the work improved the reliability of the synchronization process and reduced endpoint-related errors for downstream integrations. By enhancing test coverage and updating the contract with the API, the changes contributed to a more predictable customer experience and reduced the risk of future regressions, demonstrating careful attention to detail and maintainability.
