APIs are increasingly important for banks, retailers, and enterprises, but they also need to comply with regulatory standards.The Consumer Financial Protection Bureau (CFPB) has recently passed rule 1033 to protect consumer financial data.Open banking interfaces must be available and fast with uptime of at least 99.5% each month.The UK has long led the open banking movement and has set the foundation for API best practices.Securing APIs is crucial, as poorly designed APIs can expose vulnerabilities and increase the risk of exploitation.Companies should establish effective monitoring systems for their APIs to maintain compliance and prevent API drift.Recent studies show that 75% of tested APIs had endpoints that didn’t conform to standards, highlighting the need for continuous oversight.API performance and monitoring are now at the heart of financial data access and privacy regulations.
