My REST API app was just approved by clover. I'm trying to figure out the next steps so my customers can use the app. It seems like I need to submit an APK, but that doesn't really make sense since I'm not trying to integrate with any clover devices. Why would I need to mess with Android when I'm not developing on a phone or any clover devices? I've tried having my customers connect via OAUTH 2 but that does not work yet. What do I need to do to go live?
