EVENT-DRIVEN ARCHITECTURE AND API OBSERVABILITY FOR REAL-TIME FINANCIAL TRANSACTION SYSTEMS

Abstract

This study discusses how event-driven architecture and API observability can help to 
make financial transactions systems reliable in real-time. The literature discusses the 
observation of the use of asynchronous event processing and observability structures in 
enhancing scalability and the visibility of transactions. The research is based on an explanatory 
research design and secondary data analysis ass it evaluates event streaming and monitoring 
can transform financial systems through the reactive mode into proactive operations. The 
results reveal that event-driven architectures lower latency and improve resilience and large 
volumes of transactions, whereas API observability contributes to improving security, 
compliance, and end-to-end traceability. The study emphasises the need to adopt clouds, 
governance and skills training of resilient financial platforms.
