Integrating Big Data Analytics in Fintech through Cloud-Based APIs

Abstract

The rapid evolution of fintech has transformed the financial services industry, with APIs (Application Programming Interfaces) playing a pivotal role in enabling seamless data access, integration, and innovation. API-driven fintech solutions facilitate the exchange of financial data among banks, third-party service providers, and customers, fostering the development of new financial products and services. However, this increased data accessibility raises significant security and privacy concerns, necessitating robust measures to protect sensitive financial information. This paper explores how APIs enhance data access in the fintech sector while addressing the security challenges they introduce. By examining the implementation of open banking, secure API practices, and data protection frameworks, this study highlights the potential of APIs to revolutionize financial services securely.
