Hi, we're developing an app which requires login. The login is managed on our Drupal server and allows both login on site and in app. Now we want to use in-app purchase to allow users to sign up directly in the app by buying a subscription. user signup in app (choose subscription) purchase/payment is handled by apple User credentials are added/created on our server?! Step 3 - what is the right way to do this? Is there a guide somewhere?

Is it possible - in appstore - to create a subscriptions model similar to what microsoft teams and google workspace has for team memberships? We want to have a subscription price per user per month (or year). Administrator should be able to add additional users (and add a subscription for the new users) - It doesn't seem to be possible - only option is to have prefix subscriptions with 5 users, 10user, 15 users etc. (we've also looked into consumables - but the lack the option to be reoccurring payments) Thanks in advance?
