We are developing an application to be used as third party app on clover device(currently station duo). We are testing things using sandbox on Android studio emulator(station 2018 setup) for development and also got a devkit(station duo / station pro) and installed app apk on it which is working.
Regarding the payments processing, we have used REST API's to develop display order and charge a payment. These are working correctly on the emulator after installing Cloud Pay Display app on the emulator. When we try to install Cloud Pay Display app on the devkit by connecting it from Preview App Market, it is not being installed on the devkit device as it's availability doesn't include clover station duo / station pro.
1 - How can we consume REST API's in our application for a clover station duo payments? If Cloud Pay Display or REST Pay Display apps are not available for station duo then any other server app available to work?
2 - What is the alternative approach to use REST API's for clover station duo?
3 - Is there a way to access clover station duo remotely from different region. (like Anydesk is used to access windows platform remotely).
