Worked on stabilizing payment processing within the nashtech-garage/yas repository, focusing on backend reliability for order transactions. Addressed a critical bug in the payment status update flow by correcting API endpoint paths and ensuring authentication headers were properly handled for payment capture requests. This backend fix, implemented using Java and Spring Boot, improved the consistency of transaction states between order and payment services. The work enhanced API integration and reduced payment capture failures, resulting in a smoother checkout experience and more accurate revenue reporting. The contribution emphasized code quality and traceability, aligning closely with established API contracts and business requirements.
