Unity IAP Store Guides - Amazon, Apple, Google Play, Windows

Yes, obviously but that's the exact point I'm making. The ID is said to be store independent in your documentation but in reality it's not.

Code (CSharp):

1. builder.AddProduct("Money1", ProductType.NonConsumable, new IDs
2.                 {
3.                     {"gold1", GooglePlay.Name},
4.                     {"GoldOne", WinRT.Name}
5.                 });

If it was store independent it shouldn't matter what I add as the first parameter string, it should only matter what I add in the specific cases for the Purchasing.IDs storeIDs

If I'm required to add the same thing in the first string and the two later then how can I do something store independent?

 

Having investigated the Windows store ID issue I can confirm that declaring a store specific ID for 'WindowsPhone8.Name' would result in the wrong ID being used at runtime - this was a bug.

Furthermore, having both 'WinRT.Name' and 'WindowsPhone8.Name' was confusing, given that Microsoft product IDs are universal across phone and desktop when making Universal builds.

I have released version 1.2.2 of our store packages that deprecates WinRT.Name and WindowsPhone8.Name and introduces WindowsStore.Name as their replacement.

You can update your project by going to the IAP cloud service window and selecting 'import' to reimport our store packages.

@Nihil688 were you declaring a store specific ID using 'WinRT.Name' or 'WindowsPhone8.Name'? The former should have worked, the latter would not.

 

Right, I tested predominantly on Windows Universal 10 and the windows store made it backwards compatible with windows 8 which made it work.

Mind you I did get a warning from Windows Store:

 

I'm not sure why Microsoft would generate that warning, it seems to be an error on their part.

 

Hi @nicholasr ,

You suggest something like this:

Code (CSharp):

1. private void SendInfoToUnityAN()
2.         {
3.             Analytics.CustomEvent("RealMoneyPurchase", new Dictionary<string, object>
4.         {
5.              { "customSegment", _customSegmentParameter},
6.              { "prodID", "coins"},
7.              { "price", "25" }
8.         });
9. }

*And the result will be => RealMoneyPurchase "coins" "25" ?

Thanks in advance!

 

@D0R1N Correct - once Analytics has time to collect and process the data (about six hours) the `RealMoneyPurchase` Custom Event will be available in the Data Explorer for your project at analytics.unity3d.com. You'll be able to see the values set into the keys `customSegment`, `prodID`, and `price`.

 

Hi, I add init to my script:

Code (CSharp):

1. void InitializePurchasing() {
2.     var builder = ConfigurationBuilder.Instance(StandardPurchasingModule.Instance());
3.  
4.     builder.AddProduct(FULL_VERSION_ID, ProductType.NonConsumable);
5.  
6.     UnityPurchasing.Initialize(this, builder);
7. }

But when I run it in iOS device i get error: "NoProductAvailable".
ID is true and registered in iTunesConnect. I tried and new IDS() method.
I tried to on Dev mode, tried to change id but I have not more power... Help plz!

 

Have you been through the checklist here? Are you testing using an ituned connect test user account?

 

Advise

What does it means:

• Products must be cleared for sale in iTunes Connect
• It may take many hours for newly created iTunes Connect products to be available for purchase

I added the product to itunes connect:



And done Init in controller which loading with store scene:



But I taking the same error: "NoProductsAvailable".

Help. Thanks!

P.S. App is in TestFlight. And I log out from iTunes store. Sandbox user needed for purchase not for initialization.

 

You are logged out of the App store before you launch your App?

Can you DM me your product IDs if you are not happy to share them here?

 

Hi,

Im having some difficulties with this plugin. already setup it as the guide say,have a beta published with an item, the unity editor say pass when i test it, my item and my id in google play and unity are the same. but the popup never show up...
I tested it many times.

any light?

 

Please take and attach a trace using adb, from when your application starts up and attach it to this thread.

 

Sorry, it's working nicely, looks like my co worker updated a new version to google developer and it was in publishing again.

Feel really ashamed to bother you.

Just to other people, i see many tutorials about this and they upload the test apk in alpha open, the test apk also work in beta close.

 

Hi @resetme,

No need to feel ashamed, that's what the forums are here for! Glad it's all working now!

 

Hi there, I'm trying to get IAP working on WP8.1.
We got all the packages ID in app, we got the proper c# code, we got the proper packs on WP store set up.
The thing is, that everytime we try to start the app on WP8.1, we get this:

UnityIAPWin8:Exception loading listing information:Exception from HRESULT: 0x805A0194

Could someone please decode this machine jibberish into some human-readable and fixable form? Thanks in advance.

 

Have you installed your Application from the store, not sideloaded from visual studio?

 

We've pushed the app to store before, but the in-app purchases still don't show up, and we have no idea why.

 

But have you installed the app from the store to do your testing?

 

The above exception was provided from Visual Studio test.
We've perfmormed testing on the app from the store also, with no results from shop also - should we look more into it?

 

This error suggests that your App ID is not known. If you are sure your details are correct I suggest filing a support ticket with Microsoft.

 

Hey there !
Any one here to help?
I am getting an IAP not initialized error on both iOS and android. I have followed exactly the same code from the tutorial, Any fixes?

 

I'm having a terrible issue in iOS. Every time the user restarts the app Unity's IAP loses the purchase receipt from non-consumable items the user got. So I'm having to force my users to "Restore Purchases" every time the app runs anew.

The documentation for Product.receipt states: "Consumable receipts are not saved between app restarts.". Which obviously should mean that non-consumable receipts ARE saved between restarts. Only they are not. When testing in Sandbox mode I figure it was an issue there, but it's still happening on the actual App Store.

I ask first that you implement this correctly. Receipts for non-consumables SHOULD be persisted between restarts, just like Unibill used to do and Prime31 does (and like your docs imply you would).

Secondly, if that doesn't happen in the next patch, that you document a proper way to verify with the app's receipt. How that is not part of these guides is beyond me.

 

Hey @Adnan2012 ! Sorry to hear about the initialization failure. Generally the application logs on iOS and Android will shed useful light on the issue, and similarly so will the value of the initialization result parameter (InitializationFailureReason) passed into `OnInitializeFailed`.

Would you be game to share some text from those logs here, and also paste the failure parameter's value?

@LotusBlack What devices / OS versions are you seeing purchase restoration failure on?

The Apple Sandbox service supports purchase restoration.

Unity IAP persists non-consumable purchases in a device-local transaction log.

Is the game returning
`PurchaseProcessingResult.Complete` from its `ProcessPurchase` implementation?

 

Hi Nicholasr Sir!
Thanks allot for answering my query. Bad of me, I was actually wasn't doing alpha testings stuff properly. Working fine now super thanks.
I was just curios to know about the consumable products in Unity IAP. How does unity handle it as Google Play Managed IAP?

• If you are using the Version 3 API, you can also consume managed items within your application. You would typically implement consumption for items that can be purchased multiple times (such as in-game currency, fuel, or magic spells). Once purchased, a managed item cannot be purchased again until you consume the item, by sending a consumption request to Google Play.
  http://developer.android.com/google/play/billing/api.html

How Unity is sending consumption request? If it's sending!

 

Unity IAP sends the consumption request when you return PurchaseProcessingResult.Complete from your ProcessPurchase method, or, if you return PurchaseProcessingResult.Pending, when you call IStoreController.ConfirmPendingPurchase at a later date.

 

@LotusBlack Sorry, the docs need clarification here.

Apple provides a single receipt for the whole application. When a product is purchased, that receipt is associated with the product that was purchased, but that association does not persist between App restarts.

To determine what a player is entitled to on Apple stores you should parse the App receipt, within which is a list of product Ids that the player has bought.

We have been working on a library to help with validating and parsing Apple receipts, which should launch this week. I will update this thread when it does.

 

@Banderous Glad to hear, I actually implemented the simplest workaround I could think as a contingency issue, if anyone else is wondering: I'm saving to PlayerPrefs a string with the App Store ID when a PurchaseProcessed event happens (it can happen from a RestoreTransactions too, so that's good).

 

Hello,
I just can't find any info about how to retrieve price from store using Unity IAP
Is it possible?
Thank you

 

p.metadata.localizedPriceString

Where p is a Product object from IStoreController.products.all

[edit]Oh, you can also use p.metadata.localizedPrice, for a decimal value instead of a string.[/edit]

 

oh, got it
Thanks a lot)

 

@LotusBlack Version 1.3.0 of our store packages is now available, installable via the IAP cloud service window. It features a receipt validation and parsing library documented here which you can use to determine what a user is entitled to in an Apple or Google purchase receipt.

 

@Banderous Excellent! I do have a question about how the receipt works though: I noticed that if I call IAppleExtensions.RefreshAppReceipt, I get a trigger for iTunes login, just as if I tried to RestoreTransactions. But shouldn't RestoreTransactions also refresh the receipt itself? So what's the diff between the two?

And is the receipt cached somehow after each purchase the user makes by Unity?

Correct me if I'm wrong, but the way I see it working is that I only call RefreshReceipt/RestoreTransactions on a fresh install? And then validate purchases each time the app runs, using the cached receipt?

 

Yes, I believe restore transactions and refresh transactions are very similar in how Apple implements them; the authentication is required to fetch the signed receipt from Apple's servers. The difference with restore transactions is that the transactions are then replayed.

You can read the app receipt from local storage, as you suggest. That doesn't need any authentication.

 

@Banderous Since I got your attention...

Wouldn't it now be the natural evolution to have the Unity IAP lib just run these validators behind the scenes and to us users we'd just check each non-consumable product in our list with .hasReceipt to unlock the IAPs?

That's how it's working for Android right now, so I assume it's in your to-do with Apple?

 

@LotusBlack @Fattie There is a risk in making Unity IAP 'authoritative' - we want to avoid providing a single target for cracking tools that will unlock IAPs in every Unity game.

We are already running that risk by providing this reference receipt validation implementation, which is why we will be open sourcing it - so that others can modify it and increase the diversity of implementations.

Consider Apple's receipt validation strategy which is simply to provide a specification for their receipt format and a high level overview of how to validate it - there is no reference implementation.

I'm afraid I don't have a list of volume Unity IAP customers at present.

 

Hey again @Banderous !

Is it not how the lib is working for Android right now? Apparently on Android .hasReceipt is returning true, even after restarting the app and not restoring purchases. Or is there some behind-the-scenes difference that eludes me?

Also, another concern about the lib in general:

The way it is now, it does not initialize properly without internet connection, correct? But why? Don't we have the cached receipts and don't we feed in the products to the ConfigurationBuilder anyway?

So it could probably succeed with a warning in the case where the player has no active internet connection and just say the prices can't be fetched (and purchases obviously fail), but otherwise work off of the cached receipts.

 

Hi @LotusBlack-- don't forget, Android sort of "automatically" restores purchases, as do other stores. it's only Apple where you have to explicitly restore purchases.

indeed if you scroll down to `RestorePurchases()` in the excellent example code http://unity3d.com/learn/tutorials/topics/analytics/integrating-unity-iap-your-game-beta

it's basically only for Apple, it skips out otherwise. our kodes..

Code (CSharp):

1.     // note Apple (alone) currently requires explicit purchase restoration
2.     public void RestorePurchases()
3.         {
4.         if (!IsInitialized())
5.             {
6.             Debug.Log("RestorePurchases fail, not initialized. Try later?");
7.             return;
8.             }
9.  
10.         if ( Application.platform != RuntimePlatform.IPhonePlayer && Application.platform != RuntimePlatform.OSXPlayer)
11.             {
12.             Debug.Log("RestorePurchases, it is NOT necessary to restore purchases on " + Application.platform);
13.             return;
14.             }
15.  
16.         Debug.Log("Since this is an Apple device, restoring purchases explicitly...");
17.         var apple = iExtensionProvider.GetExtension<IAppleExtensions>();
18.         apple.RestoreTransactions((result) =>
19.             {
20.             Debug.Log("RestorePurchases continuing: " + result + ". If no further messages, no purchases available to restore.");
21.             });
22.         }

BTW. I've never seen any reason not to simply: always call for restore whenever the app is actually launched. Users rarely launch apps, they just put them to the background. I think it's actually reassuring to users to see that it's explicitly picking up their unlocks and dragon clothes, when they do a full-open of the app.

 

@LotusBlack Google Play features its own cache, so will typically initialise even if you don't have Internet connectivity.

On Apple stores you can read the app receipt from the device storage regardless of Internet connectivity.

@Fattie Thanks! Unity IAP adds the relevant permissions and activity on Android (they're in the GooglePlay.aar), on Apple stores it links in the storekit framework using the plugin importer settings. I'm not aware of plist modifications on iOS, though they are on the Mac App store.

Unity merges together the manifests of all the different android archives in your project. If other plugins have elements in their manifests they will be merged into the final app manifest.

 

You don't need to explicitly tell Unity IAP what your product ID is on every platform:

Unity IAP assumes this product is called "GREENEGGS" on every platform.

If you add a different store specific ID for a specific platform, it will still be known as "GREENEGGS" on all the other platforms.

Also from this snippet:

Code (CSharp):

1. private void PurchaseSUCCESSFULpidknown( string PID )
2. {
3.         if (consumables.Contains(PID)) { SuccessCONSUMable(PID); return; }
4.         if (nonconsumables.Contains(PID)) { SuccessNONconsumable(PID); return; }
5. }
6.  

You don't need to keep a list of what is consumable or non consumable, the type of the purchase is available on the purchase arguments:

Code (CSharp):

1. public PurchaseProcessingResult ProcessPurchase(PurchaseEventArgs args)
2. {
3.     Debug.Log(args.purchasedProduct.definition.type);
4.     // ...
5. }

 

"You don't need to explicitly tell Unity IAP what your product ID is on every platform"

Ahh! beautiful. So to be clear, say I do precisely this

Code (CSharp):

1. builder.AddProduct(
2.    "localCode", // probably the same, i.e.: "JELLYBOMBS"
3.    ProductType.Consumable, // or one of the other two
4.    new IDs(){{ "JELLYBOMBS", AppleAppStore.Name }, });
5.            // notice I happened to use AppStore, and only gave ONE store
6.  

- notice I happened to use only ONE of the stores
- I assume it does not matter WHICH store I happened to use

Result, `builder` now assumes JELLYBOMBS is available in ALL stores. (And indeed the code is "JELLYBOMBS" in all stores.)

This is quite correct?

Is there an issue with ... what if some items are not available in some stores? Does the system inherently believe "each item, should be in all stores"? (For the record, I would firmly agree that is how the system should work. I can't see any reason one would have something not available in one store or the other.)

----

"You don't need to keep a list of what is consumable or non consumable, the type of the purchase is available on the purchase arguments:"

Brilliant. I have to start reading these "A P I" things one day :O

 

Code (CSharp):

1. builder.AddProduct("JELLYBOMBS", ProductType.Consumable);

Then just create your product as 'JELLYBOMBS' in every store. If it has to be different for some reason on one or more stores, then you need to provide the overrides on those stores.

 

Ahh! For goodness sake - if only I'd looked at the doco

Contents/Documentation/en/ScriptReference/Purchasing.ConfigurationBuilder.AddProduct.html

With this call

it does in fact make the local ID the same as the store ID.

(Since Android is only lowercase, for anyone first making IAP in Apple, it's best to go with lowercase in Apple - then they are all the same.)

So, so long as your Apple and Android ids are the same (and hence, all lowercase since PlayStore is only lowercase), you can just do this

Code (CSharp):

1. builder
2.    .AddProduct("manyjellybombs", ProductType.Consumable)
3.    .AddProduct("bigdragons", ProductType.NonConsumable)
4.    .AddProduct("lasertoes", ProductType.NonConsumable);

and that's the end of it. The local code is then the same as (both) app stores. Awesome.

 

Hello everyone!

I'm trying to implement IAPs to my Windows 10 game. Everything works fine at the editor, 0 errors, succesful purchases. But when I debug the project through Visual Studio on my local computer, I get a NullReferenceError.

Now the Visual Studio debugger does not show where the error is, but I was sure I didn't have such error BEFORE I started to implement IAPs so I slowly disabled parts of the IAPDemo.cs code which came with the imported files through services.



If I comment out the highlighted part, my game works fine. If I let it run, I get a NullReferenceException.

Anyone knows whats up?

Unity version 5.3.1f1.

Thank you for the help!

 

Hello, I am getting issue in Initializing the product id at Unity Window's IAP store while it's working fine in Unity_Editor but getting issue when i export it for Window 10 and run from visual studio 2015.

Code for Initializing is :


public void InitializePurchasing()
{
// If we have already connected to Purchasing ...
if (IsInitialized())
{
// ... we are done here.
return;
}

var module = StandardPurchasingModule.Instance();

// Create a builder, first passing in a suite of Unity provided stores.
var builder = ConfigurationBuilder.Instance(module);

// Add a product to sell / restore by way of its identifier, associating the general identifier with its store-specific identifiers.
builder.AddProduct(kProductIDConsumableGrassStack500, ProductType.Consumable, new IDs(){{ kProductIDConsumableGrassStack500, WindowsStore.Name }});// Continue adding the non-consumable product.
builder.AddProduct(kProductIDConsumableGrassStack1500, ProductType.Consumable, new IDs(){{ kProductIDConsumableGrassStack1500, WindowsStore.Name }});// Continue adding the non-consumable product.
builder.AddProduct(kProductIDConsumableGrassStack3000, ProductType.Consumable, new IDs(){{ kProductIDConsumableGrassStack3000, WindowsStore.Name }});// Continue adding the non-consumable product.
builder.AddProduct(kProductIDConsumableGrassStack5000, ProductType.Consumable, new IDs(){{ kProductIDConsumableGrassStack5000, WindowsStore.Name }});// Continue adding the non-consumable product.
builder.AddProduct(kProductIDConsumableGrassStack10000, ProductType.Consumable, new IDs(){{ kProductIDConsumableGrassStack10000, WindowsStore.Name }});// Continue adding the non-consumable product.
builder.AddProduct(kProductIDNonConsumableRemoveAd, ProductType.NonConsumable, new IDs(){{ kProductIDNonConsumableRemoveAd, WindowsStore.Name }});// And finish adding the subscription product.
UnityPurchasing.Initialize(this, builder);
}


Do i need to setup some setting in Unity or need to edit the code?

 

Say @Banderous and guys,

just to be clear, adding ANALYTICS to a project, does NOT add any libraries or packages (we can see in Project), is that right?

I got confused: I stripped everything out of a project and was re-adding it. For IAP indeed it adds

/Plugins/UnityPurchasing/

folder. However to turn on only Analytics, it adds ... nothing? That's all correct? Cheers

 

Hey @Fattie,

That is correct, when enabling Analytics from the Services window in the editor no libraries or packages are added to your project since Analytics is now integrated directly into the editor starting from version 5.2.

 

Hey guys,

so I'm also struggling with the same problem Lotus was describing two weeks earlier: The non-consumable product has been bought. The iTunes store knows I bought it, it's all fine unless I restart my application. Then the product is gone, I cannot rebuy it, since iTunes knows it already has been bought and the world is sad.

So when I get it right, I would call this code for iOS after the Purchasor has been initialized?

Code (CSharp):

1. #if UNITY_ANDROID || UNITY_IOS || UNITY_STANDALONE_OSX || UNITY_TVOS
2. var builder = ConfigurationBuilder.Instance(StandardPurchasingModule.Instance());
3. // Get a reference to IAppleConfiguration during IAP initialization.
4. var appleConfig = builder.Configure<IAppleConfiguration>();
5. var receiptData = System.Convert.FromBase64String(appleConfig.appReceipt);
6. AppleReceipt receipt = new AppleValidator(AppleTangle.Data()).Validate(receiptData);
7.  
8. Debug.Log(receipt.bundleID);
9. Debug.Log(receipt.receiptCreationDate);
10. foreach (AppleInAppPurchaseReceipt productReceipt in receipt.inAppPurchaseReceipts) {
11. if (productReceipt.productID == "myAppleID")
12. {
13. startMyFunctionForActivatingTheNonConsumable();
14. }
15.     Debug.Log(productReceipt.transactionIdentifier);
16.     Debug.Log(productReceipt.productIdentifier);
17. }

Or am I getting something wrong here?

 

Yes, that ought to work assuming your product ID is correct. I suggest you debug log details of every product in the receipt to see what it contains and ensure you are checking for the right ID.

 

Okay I have to test that on iOS. I have another question concerning the receipt-validation on Google.
I checked it pretty simple before like "if the purchaser is initialized and has the specific product ID, then switch on the non consumable product."
Then I wrote your topic about validation and now I'm running into problems, since I don't know what exactly I should validate here. I took this code

Code (CSharp):

1.     public void testfunctionAfterInitialize()
2.     {
3.         // Unity IAP's validation logic is only included on these platforms.
4.     #if UNITY_ANDROID
5.         // Prepare the validator with the secrets we prepared in the Editor
6.         // obfuscation window.
7.         var validator = new CrossPlatformValidator(GooglePlayTangle.Data(),
8.             null, Application.bundleIdentifier);
9.  
10.         try {
11.             // that's the line I don't think I'm correct here can I do this with the validator that has a "null" value for the AppleTangle.Data()?
12.             var result = validator.Validate(m_storeController.products.withID("myProductID").receipt);
13.             if (result != null)
14.             {
15.                 this.startReCreationFunction();
16.             }
17.             }
18.             // Unlock the appropriate content here.
19.         } catch (IAPSecurityException) {
20.             Debug.Log("Invalid receipt, not unlocking content");
21.         }
22.     #endif
23.     }    

but now this startRecreation() function is not called and the content is not accessible anymore.
Can you tell me where I'm wrong?

 

Isn't receipt validation automatic in Android though? Your product.hasReceipt methods should be returning true on Android even after reinitializing (reinstalling??) the app, from what I tested.
