Iam using visa checkout sdk on ios app. Everyting seems going correctly, but i am confused with the result.encryptedKey and
encryptedPaymentData , How do i decrypt them ? Should i do it from app side or do from my backend server. Please provide solution with example.
Decryption must take place outside of the app, as the app is not secure. The attached two guides indicate both transaction flow and how to complete it.
Please find attached for detail example in A -1 of Visa Checkout Integration Giuide.
