Hey, guys! I'm still working on my mobile multiplayer survival game. In my article titled Build a Game That Features Local In-App Purchases, I shared my experience of configuring in-app product information in the language and currency of the country or region where the user's account is located, which streamlines the purchase journey for users and boosts monetization.
Some new challenges have arisen, though. When an in-app product is configured, I need to test its purchase process before it can be brought online. Hence, I need a virtual purchase environment that doesn't actually charge me real money. Sandbox testing it is.
