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

Parameter	Type	Description
_context	Context	(Required) Android Context

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).

CautionEnsure the operation mode is set to OPERATION_MODE_PRODUCTION before submitting for Beta test or normal publication. In other words, OPERATION_MODE_TEST or OPERATION_MODE_TEST_FAILURE must be set only if the app status in Seller Portal is Registering or Updating.

Mode Description

Mode	Description
`OPERATION_MODE_PRODUCTION`	startPayment() requests are processed as specified, financial transactions do occur for successful requests, and actual results are returned (successful or failed). Note: For all other IAP SDK requests: Only items purchased in `OPERATION_MODE_PRODUCTION` mode are considered owned items.
`OPERATION_MODE_TEST`	startPayment() requests are processed as specified, except financial transactions do not occur (licensed testers are not billed for item purchases), and successful results are always returned. For details of the payment window shown in `OPERATION_MODE_TEST` mode, see below. Note: For all other IAP SDK requests: Only items purchased in `OPERATION_MODE_TEST` mode are considered owned items. In order to purchase in-app items, testers must be registered as a License Tester in the seller's Seller Portal profile. In this mode, licensed testers always get your in-app items for free. All other users see an error message if they try to purchase an in-app item.
`OPERATION_MODE_TEST_FAILURE`	All IAP SDK requests fail. It is meant to be a negative testing to ensure that your app can handle errors such as improper input and user actions.

OPERATION_MODE_PRODUCTION

startPayment() requests are processed as specified, financial transactions do occur for successful requests, and actual results are returned (successful or failed).

Note: For all other IAP SDK requests:

Only items purchased in OPERATION_MODE_PRODUCTION mode are considered owned items.

OPERATION_MODE_TEST

startPayment() requests are processed as specified, except financial transactions do not occur (licensed testers are not billed for item purchases), and successful results are always returned.
For details of the payment window shown in OPERATION_MODE_TEST mode, see below.

Note: For all other IAP SDK requests:

Only items purchased in OPERATION_MODE_TEST mode are considered owned items.
In order to purchase in-app items, testers must be registered as a License Tester in the seller's Seller Portal profile. In this mode, licensed testers always get your in-app items for free. All other users see an error message if they try to purchase an in-app item.

OPERATION_MODE_TEST_FAILURE

All IAP SDK requests fail.
It is meant to be a negative testing to ensure that your app can handle errors such as improper input and user actions.

NoteIf OPERATION_MODE_TEST is set, the pop-up below is displayed and Sandbox is shown at the top right of the payment window to indicate that the app user will not be billed for item purchases.

Request

public void setOperationMode( OperationMode _mode )

Parameters

Parameter	Type	Description
_mode	OperationMode	(Required) The IAP operating mode that controls the processing of IAP SDK API requests: `OPERATION_MODE_PRODUCTION` `OPERATION_MODE_TEST` `OPERATION_MODE_TEST_FAILURE`

Code snippet

Java

iapHelper.setOperationMode(HelperDefine.OperationMode.OPERATION_MODE_TEST);

Kotlin

iapHelper.setOperationMode(HelperDefine.OperationMode.OPERATION_MODE_TEST)

Get user-owned items

RequirementYou must call getOwnedList() whenever launching the application in order to check for unconsumed items or subscription availability.

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 (this includes canceled subscription items until their active subscription period has ended)

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

NotePurchased consumable items must be reported as consumed by calling consumePurchasedItems() to be purchased again, which can be done before or after the app user uses the item in the app. We recommend reporting all listed consumable items that have not been reported as consumed in one consumePurchasedItems() method call in order to avoid system overload or malfunction.

Request

public boolean getOwnedList
(   
    String                        _productType,
    OnGetOwnedListListener        _onGetOwnedListListener

Parameter	Type	Description
_productType	String	(Required) Type of in-app items to be returned: `item`: Both consumable and non-consumable items `subscription`: Auto-recurring subscription items `all`: Consumable, non-consumable, and auto-recurring subscription items
_onGetOwnedListListener		(Required) Name of the `OnGetOwnedListListener` interface that specifies the item data and processing results to be returned

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

( 
    ErrorVo                      _errorVO,

Purchase an in-app item

startPayment() initiates the purchase and payment transaction of the specified in-app item and can notify the end user if the purchase succeeded or failed. Returns the item data and transaction results and data specified in the OnPaymentListener interface.

You can specify a passThroughParam parameter value to enhance purchase security. During purchases with passThroughParam values created and passed by an IAP-integrated application are returned in the responses.

CautionWhen the IAP operating mode is OPERATION_MODE_PRODUCTION and the app is being distributed in the Galaxy Store, successful processing results in financial transactions (the app user will be billed for item purchases).

Parameters

Parameter	Type	Description
_itemId	String	(Required) Unique identifier value of the in-app item to be purchased.
_passThroughParam	String	Optional Unique identifier (maximum: 255 bytes) assigned by your Android app to the purchase and payment transaction.

Acknowledge a purchased consumable item

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.

NoteWe recommend reporting purchased consumable items immediately after verifying their purchase and reporting all unreported items in one consumePurchasedItems() method call in order to avoid system overload or malfuction.
