I'm thinking of making a mobile game but was curious on the high level idea with implementing in-app purchase.
My assumption is, correct me if I'm wrong, that you'd have some button to buy something in your game and when pressed it makes some kind of call to iTunes/GooglePlay to charge a certain value, and then comes back to your app if everything worked and then we would handle the changes to the game settings to show this purchase?
Is this grossly understated or in the right ballpark?
