Worked on the lifinance/contracts repository to deliver the Pioneer Demo Script API Alignment and Transaction ID Enhancement feature. This involved updating the demo script to match recent API changes, ensuring compatibility and robust transaction processing. The implementation introduced a crypto-random transaction ID generator and extended the query payload to include an external_id, supporting accurate processing by the updated API. Using TypeScript and Node.js, the developer focused on API integration, enhancing the demo’s reliability and readiness for production-like testing. The work addressed evolving API requirements and improved the script’s ability to interact seamlessly with the backend for transaction management.
