Connecting Roku Pay subscriber confirmation with web and phone apps

Building multi platform subscription service. Would like to integrate the Roku pay data for subscriber and subscription status to a universal subscriber database that can be accessed on phones and web to confirm active subscription. I have not found any documentation on the this in Roku Dev info.  Is there an acceptable/ preferred way to have web and phone apps get subscriber information? Is there an api for this? Any guidance on the topic is welcomed.

Thanks.
