Google Play Developer API version used in Unity IAP?

Hi, we've recently received a warning on our Google Play Dev Console about us having a version of Google Play Developer API older than 3.

So I was just wondering, does anyone know if Unity uses the Google Play Developer API to access products and subscriptions?

If not, does anyone know how to find where the Google Play Developer API in a project since I don't really have a clue ¯\_(ツ)_/¯

Thanks

 

We have the same issue:
"We’ve detected that your app is using an old version of the Google Play Developer API. From December 1 2019, versions 1 and 2 of this API will no longer be available. Update to version 3 before this date. Learn more"

When can we expect an update for UnityIAP to Google Play Developer API version 3?

 

Any unity support team member could give a feedback to this issue.
Same issue for me.

Using unity 2019.1.7f1 version

 

Cool ! Thank you @JeffDUnity3D

@JeffDUnity3D Thanks for your reply

 

Also receiving the same message for my game made with Unity 5.4.4p1.

@JeffDUnity3D What does Unity use the Google Play Developer API for... in-app purchases? Also, will there be anything I can do to comply with their requirement if I am using Unity 5.4.4p1?

 

@JeffDUnity3D Thank you very much!

 

@JeffDUnity3D Hi Jeff, would you happen to have a workaround for this as a temporary fix? We are using Unity's IAP plugin and trying to see if we can do a patch ourselves in case that update from you guys doesn't make it in time before we do an update for our app.

 

@JeffDUnity3D any idea how far back this will get backported? We're on 2017, but I think we need to upgrade to 2018 at least in order to get the play stores new adaptive icons working too.

 

@JeffDUnity3D Yes, I am using IAP.

Mainly worried because I am using Unity 5.4.4p1. Will I be able to update an IAP package or something?

 

@JeffDUnity3D Uggh... I have an established game and a solo developer. I tried to upgrade to the latest Unity 2017, 2018 and 2019 but framerate dropped so that's not an option for me.

@JeffDUnity3D Is there a way to talk to someone at Unity to see if there is an option (even paid) to get the fix in for the December deadline?

 

@JeffDUnity3D I didn't realize that IAP was a package in the Asset Store with compatibility back to 5.3. Looking forward to the fix. Thanks for the info!

 

Any updates on the release date of the PlayStore fix? Would be nice to able to test it before it becomes mandatory.

Thanks in advance!

@JeffDUnity3D Yes, we are using Appsflyer for receipt validation

 

Yes, we're verifying IAP on the server side too (for iOS, Google and Amazon).

 

Had me worried. I thought I was the only one. Please update here when it's available. I'm glad Unity is still supporting old versions, I can't risk to update to the latest.

 

No server validation here. Also want to second LandonC that backporting to old versions is very important for me (I'm using 5.4.4p1).

 

@JeffDUnity3D Ah yes, I worded that incorrectly.

Sorry for the confusion!

 

I have been informed by engineering that Unity IAP does not use the Google Play Developer API. We believe that affected developers may be using server-to-server calls for receipt validation or similar.

 

I am using the example code for validating purchase receipts, but I believe it's a local Tangle way from https://docs.unity3d.com/Manual/UnityIAPValidatingReceipts.html

Here is a snippet of my code:

Code (CSharp):

1.             var validator = new UnityEngine.Purchasing.Security.CrossPlatformValidator(GooglePlayTangle.Data(),
2.                 AppleTangle.Data(), Application.bundleIdentifier);
3.  
4.             try {
5.                 // On Google Play, result will have a single product Id.
6.                 // On Apple stores receipts contain multiple products.
7.                 var result = validator.Validate(args.purchasedProduct.receipt);
8.                 bool purchased = false;
9.  
10.                 foreach (IPurchaseReceipt productReceipt in result) {
11.                     if (String.Equals(productReceipt.productID, kProductIDConsumable_Common_Orbs_1, StringComparison.Ordinal))
12.                     {

 

We have confirmed that this is not a Unity IAP issue. This is an issue for developers using the Android Publisher API described here https://developers.google.com/android-publisher/ referenced by this technote announcing the V3 update timeline https://android-developers.googleblog.com/2019/03/changes-to-google-play-developer-api.html.

 

I just uploaded my app and released it to the "internal test" track and didn't receive the warning like I did before. Is everyone else still receiving the warning? Maybe this was a 1-time warning from Google? Or do I actually have to publish it to Production to get the warning?

@JeffDUnity3D Do you know if there is a way to figure out if a particular asset store plugin uses this API? I definitely do not use any publishing API in my game, but it's possible that one of my purchases from the asset store could have added it.

The first bullet point in the link states that the Google Play Developer API is used for IAP.

"The Google Play Developer API allows you to perform a number of publishing and app-management tasks. It includes two components:

• The Subscriptions and In-App Purchases API lets you manage in-app purchases and subscriptions.
  
• ..."

 

We don't use that API, that is a publisher REST API used to check product status. For example https://developers.google.com/android-publisher/api-ref/purchases/subscriptions/refund describes the POST REST API https://www.googleapis.com/androidp...scriptions/subscriptionId/tokens/token:refund Also there is this: https://stackoverflow.com/a/57334409/915990

 

Yeah this is a weird one, I only use Unity Ads, Unity IAP and Google Play Games Services Plugin (https://github.com/playgameservices/play-games-plugin-for-unity)

I had this API warning showing a few times, and then in the last month it disappeared.

I'm concluding that it was a bugged warning by google, I'll just ignore it for now and only worry about it if it appears again.

Google constantly sends me bugged warnings about things that I do not use or have in my game. It's incredibly annoying.

 

Nevermind, the warning just showed up today again.

I have no idea what could be possibly using the Google Play Developer API.

Does anything a Unity uses it?

 

No, we have checked several times by several people here. We are fairly certain at this point that it looks like a possible false positive from Google.

 

Yeah I'm getting to the same conclusion. Thanks.

 

In our case it seems to be the "play-services-drive" library that Play Games Plugin for Unity used for cloud saves before. This has changed to just use a REST API now. So our solution seems to be to not include the Drive library in our builds anymore.

@JustAnotherDude

 

I am getting this same message
And my game is totally offline no in-app purchase or ads
Any fix yet?

 

It's in your code, or another asset that you are using.

 

Mehn I have searched for days
But couldn’t find one
Any hints on how I can check cause google just told me they will take down my game if I don’t fix it

 

You could use Charles Proxy to see what component is calling the API that they mention https://support.unity3d.com/hc/en-us/articles/115002917683-Using-Charles-Proxy-with-Unity

 

Hello @JeffDUnity3D . We're using a really old Unity Purchasing version 1.11.0, released on 2017-05-01.

Can you confirm the Google Play Developer API isn't used on this one either? Should I just simply update the plugin to avoid possible issues?

Edit: I actually believe this is caused by our server-side purchases verification. I'll dig into it.

 

IAP has not used this API. It may be due to the use of a server-side purchase validation method call as you mention, or a data request from the Google Play Services API

 

Great. We just updated it on our servers yesterday. Definitely we were using v2 yet.
We have Google Play Services updated to one of the latest versions, so I doubt this could be the issue.

We're waiting now to see if this warning goes away in the Google Play console.

 

@JeffDUnity3D Coincidentally, I've run across this thread:
https://forum.unity.com/threads/google-bans-app-due-alipay-sdk.687451/

I just checked the UnityChannel.aar included in our version and I can see the following:



Should we remove this UnityChannel.aar from our project to be safe, too? We're not using the Xiaomi SDK in any way, either.

 

Yes. And you'll want to update to the latest IAP version which is currently 1.23 but we may be releasing 1.23.1 next week.

 

I think i found a work around for those of us with no in-app purchase in our game
Java library is used in all our game
For those of us using old java dk/re
You can download the google play developer api v3 compliant for java (mavens/Gradle) then install it manually
https://developers.google.com/resources/api-libraries/download/androidpublisher/v3/java
Hope this fix your issue as December is around the corner
Good luck

 

How to install it manually?
and did it worked for you?
