[Unity IAP] On auto-renewing-subscription is auto-renewed in store, what happens in Unity IAP?

I have some questions about Unity IAP's behaviour when auto-renewing-subscription is auto-renewed.
Please help.

1-1)In case not relaunching app, just make app foreground from background, Nothing happens？
1-2)Will

ProcessPurchase()

called automatically for subscription product?
1-3)Will subscription product is automatically renewed in

IStoreController.products.all 

without calling any refreshing method like

FetchAdditionalProducts() 

or

RefreshAppReceipt()

1-4)Needs

FetchAdditionalProducts() 

to reflect renewed subscription product?
1-5)Needs

RefreshAppReceipt() 

to reflect renewed subscription product?(iOS)

2)In case relaunching app,

UnityPurchasing.Initialize()

makes subscription items renewed by automatically calling

ProcessPurchase()

?

3)And what is the difference of behaviour between iOSAppStore and GooglePlayStore?

Sorry for many questions.

 

Use the SubscriptionManager to manage subscriptions. There is no need for any additional method calls. As always, make sure to test for yourself, the stores make is easy to test without using an actual credit card purchase https://forum.unity.com/threads/improved-support-for-subscription-products.532811/

 

Thank you, I'll use SubscriptionManager.

 

Hi, Is the Subscription Manager already validate the receipt? What happens when I call the IsSubscribed method or the IsCancel method? Should I validate the receipt anyway?

Thanks

 

You need to validate the receipt each time, we don't do that for you.

 

How to connect the apple user who paid with the user who registered in the game? I'm having trouble understanding how to know if the user logged into the app is up to date with the payment made with the user logged into the apple store.

 

For security, you (the developer) can't (and shouldn't) know. The payment process is (only) between the user and the Apple store, and is secure.

 

Good day

How I can get the updated Receipt when the subscription is auto - renewed?

 

We are tracking an issue on iOS where the receipt goes missing during a subscription auto-renewal. I'm hoping that we can address this issue in the next or upcoming release. Are you on iOS or Android?

 

Good Day Jeff

I'm Testing on Android first, for some reason when the test subscription is done unity don't update the Receipt.
Also I want know if I have to use the Google Play Billing Library:
https://developer.android.com/google/play/billing/unity

or with the last version from Unity IAP come with that?
I'm try with both, but saddly the Receipt is not updated.

 

Please show the code that you are using to check. What fields are you checking? Are you using the SubscriptionManager? I have code like this in the Sample IAP Project. It's similar to the code mentioned here

https://forum.unity.com/threads/improved-support-for-subscription-products.532811/

https://forum.unity.com/threads/sample-iap-project.529555/

Code (CSharp):

1.  public void ListProducts()
2.     {
3.  
4.         foreach (UnityEngine.Purchasing.Product item in m_StoreController.products.all)
5.         {
6.             if (item.receipt != null)
7.             {
8.                 MyDebug("Receipt found for Product = " + item.definition.id.ToString());
9.             }
10.         }
11.     }

 

Hello Jeff

this is the code to check the receipts:

Code (CSharp):

1.  
2.  public void CheckProductsReceipts()
3.     {
4.         for (int i = 0; i < storeController?.products?.all?.Length; i++)
5.         {
6.             Debug.Log("PRINT RECEIPTS " + storeController?.products?.all?[i].receipt);
7.  
8.         }
9.     }
10.  

this is the logcat from a monthly subscription test, I have that code inside the Update to validase if in any moment change:

2021-02-17 17:53:45.255 31054-31076/?

Accord Google Documentation that auto renew happen each five mins, I validase in the console the order ids:

GPA.3343-7995-0582-09647 , date: 17/2/2021 21:38 (UTC)
GPA.3343-7995-0582-09647..0 date: 17/2/2021 21:43 (UTC)
GPA.3343-7995-0582-09647..1 date: 17/2/2021 21:48 (UTC)

but the product in unity never take that change.

here is a "complete" code how i'm manager the renew:

Code (CSharp):

1.  
2.  
3. public  DateTime purchaseDate = default;
4. public  DateTime subscriptionEndDate = default;
5. public  Product currentSubscription = default;
6. public  bool testEnviroment = true;
7.  
8. public void OnInitialized(IStoreController controller, IExtensionProvider extensions)
9. {
10. storeController = controller;
11. #if UNITY_ANDROID || UNITY_IOS || UNITY_STANDALONE_OSX
12.         validator = new CrossPlatformValidator(GooglePlayTangle.Data(), AppleTangle.Data(), Application.identifier);
13. #endif
14.  appleExtensions = extensions.GetExtension<IAppleExtensions>();
15.  googlePlayStoreExtensions = extensions.GetExtension<IGooglePlayStoreExtensions>();
16. }
17.  
18. private void Update{
19. CheckProductsReceipts();
20. isPremium = CheckSuscription();
21. }
22.  
23.  
24.     public void CheckProductsReceipts()
25.     {
26.         for (int i = 0; i < storeController?.products?.all?.Length; i++)
27.         {
28.             Debug.Log("PRINT RECEIPTS " + storeController?.products?.all?[i].receipt);
29.                     if (storeController.products.all[i] != null && storeController.products.all[i].hasReceipt)
30.         {
31.             if (storeController?.products?.WithID(subscriptionMonth).receipt == storeController?.products?.all?[0].receipt)
32.             {
33.                currentSubscription = storeController.products.all[i];
34.  
35.             }
36.         }
37.         }
38.  
39. public bool CheckSuscription(){
40. nowT = DateTime.UtcNow;
41. #if UNITY_ANDROID || UNITY_IOS || UNITY_STANDALONE_OSX
42.         // I use first the validator because the Google.Play.Billing don't get the subscription manager, so this methot to //get the Purchase date works with the UnityIAP and the Google.Play.Billing
43.             if(validator != null) {
44.                 var result = validator.Validate(currentSubscription.receipt);
45.  
46.                  foreach (IPurchaseReceipt productReceipt in result){
47.                     PersistentData.purchaseDate = productReceipt.purchaseDate;
48.                     Debug.Log("DATETIME PURCHASE DATE " + PersistentData.purchaseDate);
49.                  }
50.             }
51.              if(testEnviroment == true){
52.                  timeToAdd = 300;// 300s = 5min to match the test time of monthly subscription accord google      documentation
53. subscriptionEndDate = purchaseDate.AddSeconds(timeToAdd).ToUniversalTime();
54.  }else{
55. timeToAdd = 1;// 1month
56. subscriptionEndDate = purchaseDate.AddMonths(timeToAdd).ToUniversalTime();
57.  
58. }
59.                
60.                   remainingTime = PersistentData.subscriptionEndDate - nowT;
61.                  Debug.Log(" END DATE " + subscriptionEndDate);
62.                  Debug.Log(" REMAINING TIME " + remainingTime);
63.            
64. #endif
65.    }
66. }
67.  

Yes, I also use the subscription manager, but the purchase date never change, I beleive is because this take the real 30 Days instead the test time.

Code (CSharp):

1.  
2.         if (storeController?.products?.all?.Length <= 0) { return; }

8.         for (int i = 0; i < storeController.products.all.Length; i++)
9.         {
10.             if (storeController?.products?.all?[i].receipt != null)
11.             {
12.                 Debug.Log("SUBSCRIPCIONINF RECEIPT " + storeController?.products?.all?[i].receipt);
13.                 if (storeController?.products?.all?[i].definition.type == ProductType.Subscription)

18.                         SubscriptionManager p = new SubscriptionManager(storeController?.products?.all?[i], intro_json);
19.  
20.                         SubscriptionInfo info = p.getSubscriptionInfo();
21.                         subscriptionInfo = info;
22.                     }
23.  
24.                 }
25.                 else { Debug.Log("SUBSCRIPCIONINF the product is not a subscription product"); }
26.             }
27.             else { Debug.Log("SUBSCRIPCIONINF the product should have a valid receipt"); }
28.  
29.         }
30.         if(subscriptionInfo != null)
31.         {
32.             Debug.Log("SUBSCRIPCIONINF " + subscriptionInfo);
33.             Debug.Log("SUBSCRIPCIONINF SKU DETAILS " + subscriptionInfo.getSkuDetails());
34.             Debug.Log("SUBSCRIPCIONINF purchase date  " + subscriptionInfo.getPurchaseDate());
35.             Debug.Log("SUBSCRIPCIONINF is subscribed? " + subscriptionInfo.isSubscribed().ToString());
36.             Debug.Log("SUBSCRIPCIONINF is Autorenewing? " + subscriptionInfo.isAutoRenewing().ToString());
37.             Debug.Log("SUBSCRIPCIONINF Remaining time " + subscriptionInfo.getRemainingTime().TotalSeconds.ToString());
38.             Debug.Log("SUBSCRIPCIONINF next billing date is: " + subscriptionInfo.getExpireDate());
39.         }
40.  

logcat from SKU DETAILS:


2021-02-17 18:15:47.336 31054-31076/? I/Unity: SUBSCRIPCIONINF SKU DETAILS {"productId":"suscripcion_mes","type":"subs","price":"COP 8,000.00","price_amount_micros":8000000000,"price_currency_code":"COP","subscriptionPeriod":"P1M","title":"suscripción Mensual","description":"accede a todo el contenido durante un mes”,"skuDetailsToken":"AEuhp4KkgDaNxp0Q5avRMoLyJvYJZxcYkFqP2geE4xckhMpIDYtkp0zkHPrSWZzxsRK_"}

I'm not sure, if calling that metods inside the update maybe that causing the trouble. The reason I have that the Update is because I want see the moment when the change happens and be sure the timer is working fine.

 

Hello Jeff.
Is there a way to check whether the user is still subscribed after the auto-renewal? Since the receipt goes missing I have trouble finding a workaround.

 

I'm not familiar with a work around, other than tracking dates yourself. We are working on this issue

 

I'm sorry, I am not sure I understand how to track the dates. If I'm understanding well, the expiration date given by the SubscriptionManager gives the date of the end of the first subscription. How could we track the dates of the renewed subscriptions if we have no receipts of them?

 

Yeah, good point. The assumption was that they successfully renew their subscription each month, but you would be blindly awarding the product which would be a non-starter, we are still working on this.

 

Can I use SubscriptionManager for both iOS and android?
How can I change subscription time?

 

You can't change the subscription time. You mean like Weekly vs Monthly? You would need separate products.

 

Did you found a solution for this issue? In Android it works perfectly, but in iOS when i use FetchAdditionalProducts for the subscription after an auto-renewal it seems the receipt doesn't get updated. Additionally, if i close the game and open after the expiration time for the first receipt i don't receive a receipt next time i enter the game.

 

How are you using FetchAdditionalProducts? What if you front load all the products? Does the subscription show up during Restore?

 

I currently load at start all the products, then fetch is called only for the auto-renewal subscription to update its receipt every 5 minutes (I'm aware it would be better to call the fetch once after the expiration occurs).

Something i forgot to mention, this behavior is happening on testflight, so after 5 minutes the subscription expires (we are using a 1 month subscription).

 

You don't want to fetch products again if you've already loaded them. The method is only meant to be used as the name implies. I'll look forward to the Restore results

 

In the documentation it says that FetchAdditionalProduct refresh metadata on existing products, in android i found this was the only way i got the receipt updated after it expired, maybe i understood wrong how it works. Even so, when closing and opening the app after a subscription expires it doesn't gets an receipt.

PS. I'm working on getting the restore results, but will take a while.

 

FYI Apple requires an IAP Restore button. If the subscription expires, you won't get a receipt.

 

How can i get the expiration date for the next subscription cycle if i don't get a new receipt?

 

Sorry I don't quite follow. If the subscription expires and they don't renew, there should not be a receipt. If they have an active or renewed subscription, the receipt should be available. We have heard of reports that receipts for autorenewing subscriptions go missing in Sandbox, seems to be an Apple issue. Should not occur in a released game.

 

Sorry, let me try to explain better my issue:

I have an auto-renewable subscription that renews monthly. I'm currently making tests in testflight and I'm seeing that when the first month (5 minutes in testflight) pass, if i close the app and then reopen the game there's no receipt, however since it is a renewable purchase it should have a receipt for the next month.

Additionally, I'm seeing that when the time for the first month pass with the app open, the subscription gets Expired, this makes sense since the receipt only has as expiration date the end of the first subscription period, at this point i should update somehow the receipt to check for a new expiration date.

How can i get that new expiration date for the next month if i don't receive a new receipt?

 

Yes it should. Please see my edited previous post.

 

Thanks a lot for your answer

 

As I know, if we call UnityPurchasing.Initialize at the start of the game, the receipt can be updated if subscription is auto-renewed.

But if the game is opened when the subscription is auto-renewed. How can I get updated receipt? Does it automatically update? I just need to loop through IStoreController.products.all and these products have new receipt?

 

Good day Jeff,

I am recently working on auto renewable subscription based products. is this resolved as I am not getting solution to read particular receipt to restore and renewal purchase both for iOS and Android. Please help
Thank you

 

Hello Jeff
I don't think it's an apple issue. I have an app that has been around for a while (over 980 test subscription receipts worth) and I'fe just upgraded to Unity 2021.3.20 LTS and IAP 4.7.0.
Test monthly subscription does. not automatically detect the renewed receipt after 5 mins. I have to press the subscribe button again and wait for the "You are already subscribed to this....." message.
It all worked fine previously with Unity 2020.3.33 and IAP 4.5.2
I don't just want to release an update in case it's NOT just an Apple Sandbox issue.
Are you able to 100% confirm that actual real subscriptions won't go missing in store version?

 

Hi Yannick_D

Ok thanks for the update and reassurance. Just get a bit worried when there are updates from Unity and updates to iOS and then things that used to work stop (in Sandbox), Too many moving parts

 

On iOS we are noticing a small amount of subscription receipts are going missing on renewal. We are seeing it most often with subscriptions that have free trials- probably because they renew the quickest.

In support emails we print out the user's raw apple receipt information (from code the found here https://docs.unity3d.com/Manual/UnityIAPValidatingReceipts.html.) We also have an inconvenient way to fetch receipts through our backend from Apple. When we obtain the users receipts using our backend we can see the missing subscriptions are actually there.

To us it's appearing like receipts in game are not always being correctly updated on renewal. Even having these people do a restore purchase doesn't seem to update the receipts in the game.

We are using In App Purchasing 4.7.0. Any suggestions to what might be going on?

 

The 'Validate' function is not updating my expiration date on iOS for auto-renewal. On my Apple ID, I can see that the app has renewed and will expire in six months. However, within the app itself, the subscription shows as expired. When I call 'validate' it does not update my receipt and still displays an old expiration date. Is there any specific function we should call to update the receipts besides `validator.Validate(receiptData)`? Unity 2021.3.17f1

Code (CSharp):

1. ConfigurationBuilder builder = ConfigurationBuilder.Instance(StandardPurchasingModule.Instance());
2.                 IAppleConfiguration appleConfig = builder.Configure<IAppleConfiguration>();
3.                 if (string.IsNullOrEmpty(appleConfig.appReceipt) == false)
4.                 {
5.                     byte[] receiptData = Convert.FromBase64String(appleConfig.appReceipt);
6.                     AppleValidator validator = new AppleValidator(AppleTangle.Data());
7.                     AppleReceipt localAppleReceipt = validator.Validate(receiptData);
8.                     receipts = localAppleReceipt.inAppPurchaseReceipts;
9.                 }

Code (CSharp):

1. for (int i = 1; i < receipts.Length; ++i)
2.             {
3.                     AppleInAppPurchaseReceipt receipt = (receipts[i] as AppleInAppPurchaseReceipt);
4.                 if (IsAppleSubscriptionReceipt(receipt))
5.                 {
6.                     if (IsAppleSubscriptionReceipt(latestReceipt) == false)
7.                     {
8.                         latestReceipt = receipt;
9.                     }
10.                     else
11.                     {
12.                         DateTime receiptExpirationDate = receipt.subscriptionExpirationDate;
13.                         DateTime latestExpirationDate = latestReceipt.subscriptionExpirationDate;
14.                         if (receiptExpirationDate > latestExpirationDate)
15.                         {
16.                             latestReceipt = receipt;
17.                         }
18.                     }
