IAP SDK Programming

Instantiate Samsung In-App Purchase

Before your app can make IAP requests, it must call getInstance() to create a singleton instance of IapHelper.

Request

public static IapHelper getInstance( Context _context )

Parameters

Return Value

IapHelper

Code snippet

Java

private IapHelper iapHelper = IapHelper.getInstance(context);

Kotlin

private val iapHelper: IapHelper = IapHelper.getInstance(context)

Set the IAP operation mode

IAP supports three operational modes. One is for enabling billing for item purchases and the other two are for testing IAP functions without billing app users for item purchases.

If setOperationMode() is not called, operation mode is set to OPERATION_MODE_PRODUCTION by default (testing is not supported, but beta release and normal publication are supported).

Request

public void setOperationMode( OperationMode _mode )

Parameters

Code snippet

Java

iapHelper.setOperationMode(HelperDefine.OperationMode.OPERATION_MODE_TEST);

Kotlin

iapHelper.setOperationMode(HelperDefine.OperationMode.OPERATION_MODE_TEST)

Get user-owned items

getOwnedList() returns a list of in-app items that the app user currently has from previous purchases:

• Consumable items that have not yet been used and not yet reported as consumed
• Non-consumable items
• Subscription items currently in a free trial or an active subscription period
  • Includes canceled subscription items until their active subscription period has ended
  • If the subscription price is changed, includes information such as new price, renewal date, and user consent

getOwnedList() also returns item data and processing results specified by the OnGetOwnedListListener interface.

Request

public boolean getOwnedList
(   
    String                        _productType,
    OnGetOwnedListListener        _onGetOwnedListListener
)

Parameters

Return value

• true - The request was sent to server successfully and the result will be sent to OnGetOwnedListListener interface listener.
• false - The request was not sent to server and was not processed.

Response

void onGetOwnedProducts(ErrorVo errorVo, ArrayList<OwnedProductVo> ownedList)

Parameters

OwnedProductVo

Notify Samsung IAP that the purchase was processed

After your app has granted entitlement to the user with a successful transaction, your app needs to notify Samsung IAP that the purchase was successfully processed.

The following sections describe the process for acknowledging different types of purchases.

Consumable items

consumePurchasedItems() reports one or more purchased consumable items as consumed, which makes the items available for another purchase. The app user may or may not have used the items. Returns item data and processing results specified by the OnConsumePurchasedItemsListener interface.

Request

public boolean consumePurchasedItems
(
  String                             _purchaseIds,
  OnConsumePurchasedItemsListener    _onConsumePurchasedItemsListener
)

Parameters

Return value

• true: The request was sent to server successfully and the result will be sent to OnConsumePurchasedItemsListener interface listener.

• false: The request was not sent to server and was not processed.

Response

void onConsumePurchasedItems(ErrorVo errorVo, ArrayList<ConsumeVo> consumeList)

Parameters

Non-consumable items and subscriptions

acknowledgePurchases() acknowledges that the user has been granted entitlement for one or more purchased nonconsumable items or subscriptions. Returns item data and processing results specified by the OnAcknowledgePurchasesListener interface.

Request

public boolean acknowledgePurchases
(
  String                             _purchaseIds,
  OnAcknowledgePurchasesListener     _onAcknowledgePurchasesListener

Get promotion eligibility for subscription

getPromotionEligibility() returns the pricing options of a subscription item, such as free trials and introductory prices, applicable to the customer.

public void getPromotionEligibility
(
  String _itemIds,
  OnGetPromotionEligibilityListener onGetPromotionEligibilityListener
)

Change subscription plan

changeSubscriptionPlan() allows your customer to change their existing subscription to another tier of the same subscription item.

A change may be an upgrade (from a lower priced tier to a higher priced tier or changing between two equally priced tiers) or a downgrade (from a higher priced tier to a lower priced tier).

You must specify a prorationMode to choose how to apply changes to the payment and current subscription period.

Request

public boolean changeSubscriptionPlan
(
  String _oldItemId,
  String _newItemId,
  ProrationMode _prorationMode,
  OnChangeSubscriptionPlanListener _onChangeSubscriptionPlanListener

String _oldItemId,
String _newItemId,
ProrationMode _prorationMode,
String _passThroughParam,
OnChangeSubscriptionPlanListener _onChangeSubscriptionPlanListener
)

Return value

• true - The request was sent to server successfully and the result will be sent to OnChangeSubscriptionPlanListener interface listener.
• false - The request was not sent to server and was not processed.
