Can I restore former Items without adding former products when do UnityPurchasing.Initialize()?

I changed shop item lineups, but I want to enable to restore former Subscription/NonConsumable items.

Can I restore former Subscription/NonConsumable Items even if I do

UnityPurchasing.Initialize() 

only with new products?

Or I must add former products with new items when

UnityPurchasing.Initialize() 

?

(in iOS/Android)

 

Please don't multipost. Please define "shop item lineups" but restore former items? Once you sell a product, you should never delete or change the product. You can call FetchAdditionalProducts https://docs.unity3d.com/ScriptReference/Purchasing.IStoreController.FetchAdditionalProducts.html

 

Sorry for multiposting. Thank you for the information of FetchAdditionalProducts! I'll try this.

 

I want to ask one more question.

If I add new Items in store dev console after UnityIAP is already once initialized,
can't I get new products by

instance_of_IStoreController.products.WithID(productId)

until I call

FetchAdditionalProducts()

?

I would appreciate your reply.

 

To spell out my situation,
I'm wondering which code below is the right way to do

FetchAdditionalProducts()

to reflect newly added shop items.

1) If

instance_of_IStoreController.products.WithID(productId)

doesn't reflect newly added shop items until

FetchAdditionalProducts()

, i think this code results lacking of newly added items.

Code (CSharp):

1. ProductDefinition currentProducts = new HashSet<ProductDefinition>();
2. foreach (ShopItem item in currentShopItemInfos_in_my_server) {
3.     Product currentProduct =  StoreController.products.WithID(item.itemProductId)
4.     if (currentProduct != null) {
5.         currentProducts.Add(currentProduct.definition);
6.     }
7. }
8.  
9. if (currentProducts.Count > 0) {
10.     storeController.FetchAdditionalProducts(currentProducts, success_callback, failure_callback);
11. }

OR

2)

Code (CSharp):

1. ProductDefinition currentProducts = new HashSet<ProductDefinition>();
2. foreach (ShopItem item in currentShopItemInfos_in_my_server) {
3.     currentProducts.Add(new ProductDefinition(item.itemProductId, item.itemProductType));
4. }
5.  
6. if (currentProducts.Count > 0) {
7.     storeController.FetchAdditionalProducts(currentProducts, success_callback, failure_callback);
8. }

 

Make sure you fully test your code. Products would not be in your controller until you fetch them.

 

I got it! Thank you for your advice.

 

Please tell me one more.

On

FetchAdditionalProducts()

is called in iOS,
will an appleID password input dialog appear?

Sorry I can't test on device now..

 

No

 

Thank you!
