How do you secure fintech apps and APIs?
Fintech apps and APIs are secured by testing authentication, authorisation, transaction logic and data handling across mobile apps, web apps and payment APIs. Testers try to access other users' accounts, change amounts, replay transactions and abuse UPI, wallet or open banking flows, then give developers clear fixes.
