[Solved] How to handle a second purchase attempt of a non-consumable product

I have consumable and non-consumable and subscription product ID's in my android store.

During the "builder.AddProduct" I have identified the non-consumables as "ProductType.NonConsumable". What does the Unity IAP do with the ProductType.NonConsumable information?

What happens if the player tries to purchase the non-consumable product a second time? Does the Unity IAP trigger something that indicates that this non-consumable has already been purchased?

Code (CSharp):

1.  
2. //Initializes the IAP builder, adds products that are available for sale and supplies a listener to handle purchasing events.
3.     public void InitializePurchasing()
4.     {
5.        // If we have already connected to Purchasing ...
6.         if (IsInitialized())
7.         {
8.             // ... we are done here.
9.             return;
10.         }
11.         // Create a builder
12.         var builder = ConfigurationBuilder.Instance(StandardPurchasingModule.Instance());
13.  
14.         // Add a product to sell by way of its identifier, associating the general identifier with its store-specific identifiers.
15.         //*********** CONSUMABLE PRODUCTS ******************      
16.         builder.AddProduct(Product_100_coin, ProductType.Consumable);
17.         builder.AddProduct(Product_500_coin, ProductType.Consumable);
18.         builder.AddProduct(Product_1000_coin, ProductType.Consumable);
19.         builder.AddProduct(Product_10_scatter, ProductType.Consumable);
20.         builder.AddProduct(Product_5_splash, ProductType.Consumable);
21.  
22.        
23.         //*********** NON CONSUMABLE PRODUCTS ******************
24.         builder.AddProduct(Product_plane_jumbo, ProductType.NonConsumable)
25.  
26.         //*********** SUBSCRIPTION PRODUCTS ******************
27.         builder.AddProduct(Product_Level5, ProductType.Subscription);
28.        
29.         // Kick off the remainder of the set-up with an asynchrounous call, passing the configuration
30.         // and this class' instance. Expect a response either in OnInitialized or OnInitializeFailed.
31.         UnityPurchasing.Initialize(this, builder);
32.     }
33.  

 

So please explain the purpose of identifying the product as "ProductType.NonConsumable". (ie what does Unity do with that information)

 

Thank you for your quick check about trying to purchase a non-consumable twice.

I guess I can either keep track of all of the non-consumables that a player has purchased (and save that info in a secure data file) OR retrieve that information from the Android store each time the game is started.

So, is there a way to get from the Play store a list of non-consumables that a particular player has already purchased?
