Hello Unity Gurus! I am currently using Unity 2017.3.1 and IAP 2.2.6 for my game. Due to some reasons, it is not able to update by latest Unity version. But when it builds, app is crashing on Android devices. I tested and IAP 2.2.6 is crashing on Android devices on empty projects. So I think this is because of Unity and IAP is not compatible. Is there any solution to figure out this problem? Thanks,

While the restore function seems to work reliably with non-consumable products in sandbox / Testflight, it often doesn't return the purchased subscription product.

I'm using the Unity IAP sample code for the actual restore function. Purchasing subscription always works fine. Purchasing AND Restoring non-consumables also works fine. Restoring of the subscription: Sometimes it works, other times not. When it doesn't work, it permanently doesn't work (regardless of the number of attempts I make, restarting or re-installing the app). To make restore work again, I have to purchase the subscription again, delete and re-install and then usually it works (until I delete and re-install again).

I guess if it was a bug in my code, it would never work. The fact that it works fine on certain installs but not on others makes me think it may be a problem with Unity Purchasing or Apple.

I haven't released the app yet so I don't know if this is only a problem with sandbox environment or not.

When the billing process of UnityIAP is performed, the purchase process is performed normally, but Process Purchase may be called after the end and PurchaseFailureReason .DuplicateTransaction may be returned with an error. This phenomenon occurs only on iOS Ver14 or later. Does anyone know the cause of this? Thank you

It seems that some of my players are having the IAP controller fail to initialise, most are fine but our Crashlytics have caught many players having it fail. Cant seem to have it happen on a local device and cant see anything consistent between devices. Is there a good way to debug what could be causing this? I am on the most recent IAP version (2.2.6) but it has been happening for a while on different versions. IOS is fine, but Google play and Amazon both have the same issue.

Hi all, I have searched a lot, and with a lot, I mean really A LOT. My problem is that I can't find a working solution to validate whether a subscription in the Google Play Store & Apple App Store is still active. No YouTube tutorials on this topic, IAP documentation that isn't understandble, no forum posts with a real solution etc. The only thing I need is a piece of code that will do the thing below and work in 2021 (simplified): - Cross platform check if someone's auto renewable subscription is still active (Apple app store & Google Play Store). if(subscription.active == true){ Data.SubscriptionAccess = true; } else{ Data.SubscriptionAccess = false; } Data is a class that contains static data throughout my app. It basically enables if you can get to exclusive scenes for which you have to have a subscription. I really hope someone can come with a solution... Thanks in advance for your time!

What would be considered the best BaaS service for storing In-App purchases in an app so that the user can re-login on a different device and still retrieve this info?
I will NOT be requring any other features like chat, leaderboard etc.

My options are : - Playfab - GetBrainCloud - ChilliConnect - LootLocker - AWS or Firebase (building and maintaining the backend myself)
I am looking for an option that does not burn my wallet if the number of monthly users surges up and at the same time avoid paying the full price if there are very few monthly active users.
I am leaning towards AWS/Firebase as it fits my needs but would like to hear other people's opinions on this.

Unity version 2019.4.15f1 MacOS Catalina 10.15.2 Following documentation here: https://docs.unity3d.com/Manual/UnityIAPiOSMAS.html. At the bottom they have a section for Mac App Store. It says I must enable "Mac App Store validation", which I did I modified the Info.plist as required, ran all the codesign and productbuild commands with proper certificates, deleted the .app, and tried to install .pkg ![alt text][1] It installs, and shows in my Applications. But when launching, I get a popup to login to App Store ![alt text][2] The documentation says to use test iTunesConnect account. It's now call Appstore Connect, but yes, I created the test sandbox account and tried that. Tried deleting and creating new account. Doesn't work. When I use a test account, it complains of incorrect password (I verified 500% the password is correct, recreated the account multiple times, tried creating new test accounts many times, even waited 24 hours once). When I try to use my real Apple ID, it accepts it (no errors), but then displays this screen again. If I don't enable "Mac App Store Validation", this isn't a problem. But documentation says it must be enabled to test purchases. [1]: /storage/temp/177016-osx1.png [2]: /storage/temp/177020-osx3.png

When I looked for this function, this function was added in Android SDK 21. https://developer.android.com/reference/android/view/Display#getAppVsyncOffsetNanos() I definitely set the minimum SDK level to 19 (kitkat) But it is calling SDK 21. I thought Unity was upgrading a version of the minimum sdk somewhere, so I looked up the documentation and found this in the IAP documentation. ----- -------------------------------------------------------------------- ------ ## [1.11.0] - 2017-05-01 ### Added - FacebookStore - Facebook Gameroom Payments Lite support. Available on Unity 5.6+ when building for Facebook Platform on Gameroom (Windows) and WebGL. Preliminary documentation is available [here](https://docs.google.com/document/d/1FaYwKvdnMHxkh47YVuXx9dMbc6ZtLX53mtgyAIn6WfU/) - Apple platforms - Added experimental support for setting "simulatesAskToBuyInSandbox". Please let us know how this impacts ask-to-buy testability for you. ```csharp extensions.GetExtension().simulateAskToBuy = true; ``` - Apple platforms - Added support for setting "applicationUsername" field which will be added to every payment request to help the store detect fraud. ```csharp // Set the applicationUsername to help Apple detect fraud extensions.GetExtension().SetApplicationUsername(hashedUsername); ``` ### Requirement - GooglePlay - "Android SDK API Level 24 (7.0)" (or higher) must now be installed. To upgrade, either perform the one-time step of setting the project's "Android Player Settings > Other Settings > Minimum API Level" to 24, building an APK, then resetting to the project's previous value. Or, run the `android` Android SDK Manager tool manually and install "Android 7.0 (API 24)". Addresses build error messages: "Unable to merge android manifests." and "Main manifest has \ but library uses targetSdkVersion='24'". Note the Minimum API Level support is unchanged; merely the installation of API 24 SDK is now required for Daydream VR. ### Fixed - GooglePlay Daydream VR - Uses decoration-free Activity for purchasing - GooglePlay - Avoids sporadic price serialization exception - Apple App Stores - Improve handling of the situation where an attempt to finish a transaction fails (if the user is signed out of the store and cancels the sign in dialog, for example). The Apple store implementation will now remember that the transaction should be finished, and attempt to call finishTransaction again if the transaction is retrieved from the queue again. When this happens, the store will call OnPurchaseFailed with the reason "DuplicateTransaction"—this prevents a situation where a call to InitiatePurchase could result in no call to ProcessPurchase or OnPurchaseFailed. - Amazon - Fix for a crash when loading product metadata for subscription parent products ----- -------------------------------------------------------------------- ------ According to the above article, when the IAP becomes version 1.11, the Android sdk API version should be 24 or higher. This is too high to be called the minimum version. Is this true? Even if it's true, I should be able to run my application on kitkat. what can i do?

Hi guys, I updated Unity purchasing package to 2.2.2 and and UDP is up-to-date. However, I'm still having warning notification when I upload my app bundle to Google Play console. ![alt text][1] Am I skipping anything here? [1]: /storage/temp/177317-googlewarning.jpg

So I was using the IAP button as the tutorial showed me and the button won't work ingame only giving me this error: NullReferenceException: Object reference not set to an instance of an object UnityEngine.Purchasing.UIFakeStore.InstantiateDialog () (at Library/PackageCache/com.unity.purchasing@3.0.1/Runtime/Stores/FakeStore/UIFakeStore.cs:175) UnityEngine.Purchasing.UIFakeStore.StartUI (System.String queryText, System.String okayButtonText, System.String cancelButtonText, System.Collections.Generic.List`1[T] options, System.Action`2[T1,T2] callback) (at Library/PackageCache/com.unity.purchasing@3.0.1/Runtime/Stores/FakeStore/UIFakeStore.cs:153) UnityEngine.Purchasing.UIFakeStore.StartUI[T] (System.Object model, UnityEngine.Purchasing.FakeStore+DialogType dialogType, System.Action`2[T1,T2] callback) (at Library/PackageCache/com.unity.purchasing@3.0.1/Runtime/Stores/FakeStore/UIFakeStore.cs:128) UnityEngine.Purchasing.FakeStore.FakePurchase (UnityEngine.Purchasing.ProductDefinition product, System.String developerPayload) (at Library/PackageCache/com.unity.purchasing@3.0.1/Runtime/Stores/FakeStore/FakeStore.cs:163) UnityEngine.Purchasing.FakeStore.Purchase (System.String productJSON, System.String developerPayload) (at Library/PackageCache/com.unity.purchasing@3.0.1/Runtime/Stores/FakeStore/FakeStore.cs:132) UnityEngine.Purchasing.JSONStore.Purchase (UnityEngine.Purchasing.ProductDefinition product, System.String developerPayload) (at Library/PackageCache/com.unity.purchasing@3.0.1/Runtime/Stores/BaseStore/JSONStore.cs:354) UnityEngine.Purchasing.PurchasingManager.InitiatePurchase (UnityEngine.Purchasing.Product product, System.String developerPayload) (at Library/PackageCache/com.unity.purchasing@3.0.1/Runtime/Purchasing/PurchasingManager.cs:60) UnityEngine.Purchasing.PurchasingManager.InitiatePurchase (System.String purchasableId, System.String developerPayload) (at Library/PackageCache/com.unity.purchasing@3.0.1/Runtime/Purchasing/PurchasingManager.cs:69) UnityEngine.Purchasing.PurchasingManager.InitiatePurchase (System.String productId) (at Library/PackageCache/com.unity.purchasing@3.0.1/Runtime/Purchasing/PurchasingManager.cs:43) UnityEngine.Purchasing.CodelessIAPStoreListener.InitiatePurchase (System.String productID) (at Library/PackageCache/com.unity.purchasing@3.0.1/Runtime/Codeless/CodelessIAPStoreListener.cs:145) UnityEngine.Purchasing.IAPButton.PurchaseProduct () (at Library/PackageCache/com.unity.purchasing@3.0.1/Runtime/Codeless/IAPButton.cs:108) UnityEngine.Events.InvokableCall.Invoke () (at :0) UnityEngine.Events.UnityEvent.Invoke () (at :0) UnityEngine.UI.Button.Press () (at C:/Program Files/Games/2020.1.5f1/Editor/Data/Resources/PackageManager/BuiltInPackages/com.unity.ugui/Runtime/UI/Core/Button.cs:68) UnityEngine.UI.Button.OnPointerClick (UnityEngine.EventSystems.PointerEventData eventData) (at C:/Program Files/Games/2020.1.5f1/Editor/Data/Resources/PackageManager/BuiltInPackages/com.unity.ugui/Runtime/UI/Core/Button.cs:110) UnityEngine.EventSystems.ExecuteEvents.Execute (UnityEngine.EventSystems.IPointerClickHandler handler, UnityEngine.EventSystems.BaseEventData eventData) (at C:/Program Files/Games/2020.1.5f1/Editor/Data/Resources/PackageManager/BuiltInPackages/com.unity.ugui/Runtime/EventSystem/ExecuteEvents.cs:50) UnityEngine.EventSystems.ExecuteEvents.Execute[T] (UnityEngine.GameObject target, UnityEngine.EventSystems.BaseEventData eventData, UnityEngine.EventSystems.ExecuteEvents+EventFunction`1[T1] functor) (at C:/Program Files/Games/2020.1.5f1/Editor/Data/Resources/PackageManager/BuiltInPackages/com.unity.ugui/Runtime/EventSystem/ExecuteEvents.cs:261) UnityEngine.EventSystems.EventSystem:Update() (at C:/Program Files/Games/2020.1.5f1/Editor/Data/Resources/PackageManager/BuiltInPackages/com.unity.ugui/Runtime/EventSystem/EventSystem.cs:376) I know the generic problem with NullReferenceException but I just don't understand this.

Actually, I'm new to UNITY. In my existing project, the previous developer implemented the IAP feature in UNITY, but it is partially implemented. Now, I'm trying to implement the codeless IAP, when I'm trying to migrate from the old version to the new version of IAP I'm getting lots of errors. Even I'm deleting all the files related to the IAP of the previous version. Can anyone help to figure it out?

1st button/referrance is working remaining is not working ![alt text][1] [1]: /storage/temp/178016-iap-calling.png

We are in the process of updating to 2020.3.1f1 from 2019.4.16f1. We get this error error CS1029: #error: 'UnityFx.Purchasing requires Unity IAP service to be enabled.' This happens only on our build machine. I fixed this issue one my local machine by enabling IAP in the build settings. When I open the project directly on the build machine (from the build folder) the I can confirm that Unity IAP plugin is installed. Platform is set to iOS in the Build Settings on both machines. ------------------------------------------------------------------------------------------- Assets/Scripts/BEK/Payment/Scripts/Startup.cs(10,8): error CS1029: #error: 'UnityFx.Purchasing requires Unity IAP service to be enabled.'

hi, I am using the codeless IAP button and category. but when I am testing it after submitting it to Internal testing on google play store it shows **"the item you requested is not available for purchase"**. Knowing that I used my **template ID** from the play store instead of setting the price in the category and the app is reading the price **correctly** but when I press the button it shows the message. thank you this photo shows that the value is read from the template correctly ![alt text][1] and this is the error photo ![alt text][2] [1]: /storage/temp/178920-20210408-095503.jpg [2]: /storage/temp/178922-screenshot-20210408-095300-google-play-store.jpg

Hi, My app recently got rejected from the iOS App Store as they were not provided a receipt upon making an in-app purchase. I added the code from ; https://docs.unity3d.com/ru/2019.4/Manual/UnityIAPValidatingReceipts.html Specifically the code from ProcessPurchase; and in the Obfuscator, I obfuscate the generated secret key from the users and access in apple store connect. Am I doing this the right way and does this generate the required receipt? Thanks.

hi, i used the codless iap to make a buy button and added my price template id in the product category... Everything worked fine with no errors displayed in the editor... so i uploaded it to internal test... it even shows me the price on the button according to my location when i installed it from testers link from playstore. but when i try to click the button it shows that the product is not available
