Payment

You can sell in-game items using the in-app payment feature provided by the GAMEPOT SDK. Before checking out, you need to set Configuration by store to match the applicable store. Also, if the item has not been added to Dashboard > Payment > In-app, an error "ProductID not found" will occur.

Android

(AOS) Import in-app information

When checking out, you need to display payment information and local currency information on the page. You can use the functions below to get the current payment currency, name, etc. If it doesn't work, check your console settings.

Kotlin:

import com.nbase.sdk.Store

NBase.getProductItems() {products, e -> 
    if (e != null) {
        Log.e("NBase", e.message)
    } else {
        // In-app item information
        Log.e("NBase", products)
    }
}

Java:

NBase nBase = NBase.INSTANCE;

nBase.getProductItems((products, e) -> {
    if (e != null) {
        Log.e("NBase", "getProductItems fail: " + e.getMessage());
    } else {
        if (products != null) {
            Log.e("NBase", "getProductItems success: " + products.toString());
        }
    }
    return null;
});

        Log.e("NBase", e.message)
    } else {
        Log.e("NBase", purchase)
    }
}

Java:

import com.nbase.sdk.Store;

NBase nBase = NBase.INSTANCE;
nBase.purchase(activity, storeId, productId, metadata, options, (purchase, e) -> {
    if (e != null) {
        Log.e("NBase", "purchase fail: " + e.getMessage());
