Samsung In-App Purchase (IAP) for Galaxy Watch is a payment service that makes it possible to sell a variety of items in applications installed on a Galaxy Watch and internally manages communication with supporting IAP services and the Samsung ecosystem (such as Samsung Account, Samsung Checkout, and Samsung Rewards).
In-App items can be offered as consumable, nonconsumable, or subscription. For example, you can use IAP in the following scenarios:
Here are two examples:
Try and buy watch face
Buy an in-app item
Download Galaxy Watch Studio (formerly Galaxy Watch Designer) and create a watch face with a free trial period.
In order to charge for your application or in-app item, you must request commercial seller status and register your payment information.
See the Commercial Seller Request Guide.
You can add in-app items only after you register a binary to which Samsung In-App Purchase is applied.
