Let's say we have this case: User logs in through the uwp app and makes a purchase for one of the subscriptions associated with the app. We can request customer's b2b key to verify subscription state. In case this key got lost, is there any way to request a new one without interacting with the user?

Could you explain what's the b2b key that you mentioned, is it Microsoft Store ID key?

Yes, it's a Microsoft Store ID key, it's mainly required for this API call https://learn.microsoft.com/en-us/windows/uwp/monetize/get-subscriptions-for-a-user as I can't check the state for subscriptions without this b2b key, I want to check for the state of subscriptions without a b2b key, is there any way to do that?

Derive from official document. Currently, the only way to create a Microsoft Store ID key is by calling a Universal Windows Platform (UWP) API from client code in your app.
