Set and read obfuscated IDs

Use obfuscated account and profile IDs to associate purchases with user accounts while protecting user privacy. These identifiers help with fraud detection and can link purchases to your backend user system.
Note
Obfuscated IDs are set using 
IGooglePlayStoreExtendedService
, but read from orders using 
IGooglePlayStoreExtendedPurchaseService
.
using UnityEngine.Purchasing;class GooglePlayObfuscatedIdsSample{    static void SetObfuscatedIds(StoreController storeController, string profileId, string accountId)    {        var googlePlayStoreService = storeController.GooglePlayStoreExtendedService;        if (googlePlayStoreService != null)        {            googlePlayStoreService.SetObfuscatedProfileId(profileId);            googlePlayStoreService.SetObfuscatedAccountId(accountId);        }    }        static void ReadObfuscatedIdsUsingConvenienceFunction(StoreController storeController, Order order)    {        var googlePlayPurchasingService = storeController.GooglePlayStoreExtendedPurchaseService;        if (googlePlayPurchasingService != null)        {            var obfuscatedProfileId = googlePlayPurchasingService.GetObfuscatedProfileId(order);            var obfuscatedAccountId = googlePlayPurchasingService.GetObfuscatedAccountId(order);            //...        }    }    static void ReadObfuscatedIdsFromOrder(Order order)    {        var profileId = order.Info.Google?.ObfuscatedProfileId;        var accountId = order.Info.Google?.ObfuscatedAccountId;    }}

Listen for deferred subscription changes

When a user changes their subscription tier (upgrade or downgrade) with a deferred payment, the change takes effect at the next renewal date. Use this listener to be notified when such changes occur, so you can update your UI or inform the user about their pending subscription change.
using UnityEngine.Purchasing;class AddGoogleEventListenersSample{    void AddGoogleEventListeners(StoreController storeController)    {        var googlePlayPurchasingService = storeController.GooglePlayStoreExtendedPurchaseService;        if (googlePlayPurchasingService != null)        {            googlePlayPurchasingService.OnDeferredPaymentUntilRenewalDate += OnDeferredPaymentUntilRenewalDate;        }    }    void OnDeferredPaymentUntilRenewalDate(DeferredPaymentUntilRenewalDateOrder deferredPaymentOrder)    {        var currentOrder = deferredPaymentOrder.CurrentOrder;        var nextSubscriptionProduct = deferredPaymentOrder.SubscriptionOrdered;        //...    }}
