Oculus Keys - feature to tell which key was consumed to install the app

Is there any way to obtain the key used to install the current app (if any)?

It would be really useful for better checkout integration. For example, we might want to sell different levels of access, features, etc. in a keys-only app. Knowing the key inside the app would let us automatically configure everything at install-time and would give us an implicit link between the Oculus app and the user's account on our website.

Thanks
