Resolved Unavailable product for Google Subscriptions

Hi, I've just tested the Sample v3 IAP project from the forum for Android Platform:
https://forum.unity.com/threads/sample-iap-project.529555/

Unity Editor 2020.3.33f1
Unity In-App Purchasing 4.1.3
Testing Device: Android Samsung S21 FE
Application APK: Downloaded from Play Store

I've also setup the following:

• Google IAP Product id: gold50
• Prepaid 1 month duration subscription id: sub_monthly
• Prepaid 1 year duration subscription id: sub_yearly
• Licensed Testing account + Licence response as "LICENSED" in Google Play Console

Without any modifications to any code (simple build, upload and deploy to internal track), I've encountered an issue where the Google Subscriptions products are not able to initialize. After pressing the "Initialize" button, only gold50 as a product work and I'm able to see the test payment for test card screen. However pressing the subscription button returns the following:

BuyProductID: FAIL. Not purchasing product, either is not found or is not available for purchase

This is the adb logs for the test.

Am I doing something wrong for subscriptions or does Unity IAP not support it due to Google's new changes in May 2022?

Edit: Tested on Unity In-App Purchasing 4.1.5 and having the same issue as stated above.

 

In-app products:


Subscription:

Variables:

Code (CSharp):

1. public static string GOLD_50 = "gold50";
2. public static string MONTHLY = "sub_monthly";
3. public static string YEARLY = "sub_yearly";

Initialize button:

Code (CSharp):

1.  
2. public void MyInitialize()
3.     {
4.         InitializePurchasing();
5.     }
6.  
7.  public void InitializePurchasing()
8.     {
9.         if (IsInitialized())
10.         {
11.             return;
12.         }
13.        
14.         builder = ConfigurationBuilder.Instance(StandardPurchasingModule.Instance());
15.  
16.         builder.AddProduct(GOLD_50, ProductType.Consumable);
17.         builder.AddProduct(MONTHLY, ProductType.Subscription);
18.         builder.AddProduct(YEARLY, ProductType.Subscription);
19.  
20.         builder.Configure<IGooglePlayConfiguration>().SetObfuscatedAccountId("test1");
21.  
22.         builder.Configure<IGooglePlayConfiguration>().SetDeferredPurchaseListener(OnDeferredPurchase);
23.  
24.         MyDebug("Starting Initialized...");
25.         UnityPurchasing.Initialize(this, builder);
26.  
27.         //ProductCatalog catalog = ProductCatalog.LoadDefaultCatalog();
28.  
29.         //foreach (ProductCatalogItem product in catalog.allProducts)
30.         // {
31.         //MyDebug("Product = " + product.id);
32.         //}
33.     }

 

Understood, thank you for looking into this.

 

I've promoted the internal test to closed testing while setting the country to Singapore only, however I still have the same issue when clicking on the subscription button :

BuyProductID: FAIL. Not purchasing product, either is not found or is not available for purchase

Is there any other possible issues that could prevent subscriptions from being added?

 

I've updated the base plan for both subscription base plan to auto-renewing and after waiting a few hours it managed to successfully add the product into the IAP builder. Both monthly and yearly now works as intended with the test card payment screen for Closed Testing & Internal Test track.

Does it mean that Unity IAP 4.x at the moment does not support prepaid subscription types for Google which causes the product to not be added?

 

Same thing.

For two days I was I did many tests and checked many times. I had a subscription with no automatic renewal and I had done everything correctly but still could not find the product in the initialization.

Then I found this thread, I changed the subscription to an auto-renewing one and after an hour it works.

Maybe it would be better for Unity to write it down somewhere that non-auto-renewing subscriptions aren't supported (if so), or others will end up wasting a lot of time.

 

What's the features does Unity not support? I am still battling with this. Is free trial / grace period supported?
Also, is there an update on support?
Many thanks

 

For my issue, I was getting confused between the base plan subscription ID and the product subscription ID. All working now. Unity 2021, IAP 4.5.0

 

Hello. Did you set base plan ID or subscription product ID?

 

I'm having the same question. What's the difference between the subscription product id and the base plan id? Seems like it should be such a simple answer but I can't find any clear info, and there are no examples in the documentation.

 

I'm not positive yet, but it seems like it might be like this:

If I'm creating 2 subscriptions for both iOS and Google Play:

• "appname.premium.monthly" and
• "appname.premium.yearly"

Would it look like this in Google Play:

• subscription product id: "appname.premium."
• base plan ids: "monthly" and "yearly" ?
