Hi, I am working on an app which connects my SAAS tool where we plan merchant's stock situation. For time being, I am not going to charge merchants and app will be free for some months. Looks like, I need to integrate Billing API for the app to be approved. Since I am not going to charge sellers, is there anyway to get the approved without Billing API? Also, is there any alternate options to have the app in unlisted mode - so I can still create URL for customer from my SAAS tool directly? so Billing API is not required
