Integrate IAP Helper into Your App

To prepare for integrating IAP features and testing the integration, perform the following.

Create a project with a unique package name

Create a project in Android Studio with a package name that is different from the app registered in other app stores.

Caution : If package names are not different, app update malfunctions and problems with marketing and promotional support may occur.

Add permissions to AndroidManifest.xml

Add these permissions to AndroidManifest.xml:

com.samsung.android.iap.permission.BILLING to connect to IAP and enable in-app item registration in Seller Portal.
android.permission.INTERNET because IAP uses the internet.

<uses-permission android:name="com.samsung.android.iap.permission.BILLING"/>
<uses-permission android:name="android.permission.INTERNET"/>

Register an app and in-app items in Seller Portal

During IAP integration, you may need to test IAP features.
Samsung IAP needs information about your app and in-app items registered in Seller Portal.

With the com.samsung.android.iap.permission.BILLING permission added to your app’s AndroidManifest.xml file, you can register an incomplete app and one or more in-app items.

Note : Your app does not need to have IAP features integrated in order to register the app and its in-app items.
As IAP integration proceeds, you can upload new versions of your app and new in-app items as needed.

To register an app and its in-app items

Sign in to Seller Portal using your Samsung account.
Click Add New App
Click Android, select the default language, and click Next.

Note : After entering information in each tab, click Save.
In the Binary tab, upload your app APK.
In the App Information tab, enter fundamental app details.
In the Country / Region & Price tab,
specify a free or paid app, a paid app price, and countries to sell your items.
In the In App Purchase tab, register one or more in-app items:

a. Click Add Item

b. Enter in-app item information.

c. Click Save.

Note : For a subscription item, ensure your item registration information is correct. After saving a subscription item, you can only change its item title.

d. Verify the item is listed

e. When you add a new item, by default, it is inactive (not visible in Galaxy Store). To enable consumers to purchase the item, select it and click Activate.

Note : Don't click Submit Beta Test or Submit in this step.

For more app registration details, see the App Registration Guide.

For more in-app item registration details, see the Item Registration Guide.
