I need a prototype build around usage of all the VISA Developer Platform APIs available and access the same either from an android or an iOS App. These APIs need to be working against the sandbox environment they provide.
Can use an AWS or some kind of basic prototype server built on Java which lets your iOS app or the Android app to connect and work with the visa APIs.
Some basic stuff like call the REST services from Visa developer platform against the sandbox environment and show the result in the iOS textview would be sufficient.
