Creating In-App purchase on iTunes Connect (iOS)

When offering IAP within an an app, you must first add an entry for each individual purchase within iTunes Connect. If you’ve ever listed an app for sale in the store, it’s a similar process and includes things like choosing a pricing tier for the purchase. When the user makes a purchase, the App Store handles the complex process of charging the user’s iTunes account. There are a whole bunch of different types of IAP you can add:

Consumable: These can be bought more than once and can be used up. These are things such as extra lives, in-game currency, temporary power-ups, and the like.
Non-Consumable: Something that you buy once, and expect to have permanently such as extra levels and unlockable content.

Non-Renewing Subscription: Content that’s available for a fixed period of time. Auto-Renewing Subscription: A repeating subscription such as a monthly raywenderlich.com subscription.

You can only offer In-App Purchases for digital items, and not for physical goods or services. For more information about all of this, check out Apple’s full documentation on Creating In-App Purchase Products. Now, while viewing your app’s entry in iTunes Connect, click on the Features tab and then select In-App Purchases. To add a new IAP product, click the + to the right of In-App Purchases.
