If you have a Branded Mobile Application and want to set up in-app purchases for subscriptions, you'll use a unique Product ID for each subscription you intend to sell.
First, set up in-app purchases for subscriptions on your App Store and/or Google Play developer accounts. Once done, copy the Product IDs from those platforms and enter them in Joomag.
To enter the Product ID for a subscription:
Go to My Publications and open the collection settings.
Click the Mobile App tab.
Under In-App Purchases, find your subscription and enter the Product ID from App Store and/or Google Play.
Click Save.
