Release ONE store IAP Library API V7(SDK V21)

ONE store IAP library API V7(SDK V21.00) has been released. The main changes are as follows.

You must apply ONE store IAP library API V7(SDK V21) to the new in-app. You can migrate the in-app applied with anything over ONE store IAP library API V5(SDK V17) to API V7(SDK V21). Since ONE store IAP API V4(SDK V16) has been designed to a structure that is different from the later versions, it cannot be migrated to ONE store IAP API V4(SDK V19).

Subscription Products

Subscription products are provided instead of the monthly auto-renewal products used in SDK V19 and below. Subscription products offer various functions that allow users to directly manage subscription products within the ONE store app, as well as various functions for developers, such as promotions to attract new users and notifications of changes in subscription status.

Release ONE store IAP Library API V6(SDK V19)

ONE store IAP library API V6(SDK V19.00) has been released. The main changes are as follows. You must apply ONE store IAP library API V6(SDK V19) to the new in-app. You can migrate the in-app applied with ONE store IAP library API V6(SDK V17) to API V6(SDK V19). Since ONE store IAP API V4(SDK V16) has been designed to a structure that is different from the later versions, it cannot be migrated to ONE store IAP API V4(SDK V19).

Remove ONE store IAP API version

You no longer need to add the in-app API version in the app's manifest. API Version meta-data will be added to IAP SDK V19.

Confirming a Purchase

For apps using ONE store IAP library API V6(SDK V19) and above, a purchase must be acknowledged within 3 days. Unless the purchase is acknowledged within 3 days, it will be judged that the item has not been normally provided, and the purchase will be canceled. You can acknowledge the purchase by using one of the following methods:

• If the in-app is consumable, use PurchaseClient.consumeAsync().

• If the in-app is not consumable, use PurchaseClient.acknowledgeAsync().

For Monthly auto-renewal products, you must acknowledge the purchase only for the first billing. If ONE store IAP API V6(SDK V19) has been applied, the purchase MUST be acknowledged within 3 days. Note that if the purchase is not acknowledged within 3 days, it will be canceled.

Obtain market identification code

For IAP library V6 and above, the market identification code is necessary to use Server to Server API. You can obtain the market identification code through getStoreInfoAsync().
