Query Product Details

This is an asynchronous function that retrieves Product Details from the Google Play Console.
It returns detailed data for each product ID you provide, including pricing, currency, title, and subscription offers.

You can use the returned information to display in-game shop items or manage available subscriptions.
The function also provides Offer Tokens, which can be used later when Launching a Billing Flow.

Parameters include a list of Product IDs and a Product Type that determines whether the query targets in-app products or subscriptions.
Once the operation completes, one of two delegates will trigger — success or failure — depending on the result of the query.

Parameters

1. Product Ids

An array of product IDs to request from the Google Play Console.
Each ID should match a product you’ve configured in your Play Store listing.

---

2. Product Type

Specifies the type of products to query — either In-App or Subscription.
See EProductType for available values.

---

3. On Success

Triggered when product details have been successfully retrieved.
Returns an array of FProductDetails that includes all pricing and metadata information.
You can drag this pin to create a custom event and use the data in your shop or UI.

---

4. On Failure

Triggered when the request fails.
Returns:
- Response Code — EBillingResponseCode
- Error Message — FString with additional debug information.

Use this delegate to handle issues.

Example

In the example below, the Query Product Details node requests information for a list of in-app products retrieved from the Google Play Console.
The results are then passed to a custom event, which updates the product list in the in-game shop UI.

If the query fails, the Handle Error function is called, allowing you to process the error code and message for debugging or user feedback.

This setup can be extended for subscriptions — simply change the Product Type to Subscription and store the results for use when launching a purchase.

C++ Usage

You can fetch product details directly from C++ by providing an array of product IDs and handling success or failure through delegates.

#include "BillingCPPLibrary.h"

void UMyGameInstance::FetchProductDetails()
{
    TArray<FString> ProductIDs = { TEXT("coins_pack_1"), TEXT("premium_upgrade") };

    FOnProductDetailsQuerySuccessfulNative OnSuccess;
    OnSuccess.BindLambda([](const TArray<FProductDetails>& ProductDetails)
    {
        UE_LOG(LogTemp, Log, TEXT("Successfully retrieved %d product details."), ProductDetails.Num());
    });

    FOnProductDetailsQueryFailedNative OnFailure;
    OnFailure.BindLambda([](EBillingResponseCode Code, const FString& Message)
    {
        UE_LOG(LogTemp, Error, TEXT("Failed to query product details: %s (Code: %d)"), *Message, static_cast<int32>(Code));
    });

    UBillingCPPLibrary::QueryProductDetails(ProductIDs, EProductType::INAPP, OnSuccess, OnFailure);
}
