Does the transaction ID ever change for a user/subscription

Can I be confident that the transaction ID sent to the webhook will always be the same for the lifetime of a subscription, or do I need to use the original_transaction_id value?Since I’ll be creating a record in my DB for each new subscription, I want to make sure that I’m not creating duplicate records if a new transaction ID is created for existing subscriptions For example when it renews, or if the same Android user logs in as another user in my app. In the second case, I’d like to be able to reassociate that subscription to the current user.I’m migrating to RevenueCat from an existing system that integrated directly with Apple/Google stores. Both Apple and Google require you to keep a reference to the original (or previous) transaction/token since these will change over the lifetime of the subscription. I’m hoping that RevenueCat takes care of that headache so I can just use a single ID for the lifetime of a subscription.

Question about MTR when observer mode

Hi.I have integrated RevenueCat to my iOS app and am using it with satisfaction.I want to integrate it into my Android app as well, but I want to use it only in observer mode for the time being because of issues related to the non-comsumable life-time premium version.(Because of the risk of consuming non-comsumable items) Does it count towards MTR when I use RevenueCat only in observer mode?

Appsflyer Trial events for android

Dear Community,we are currently using RC for our subscribermanagement (full integration) and Appsflyer as attribution provider. Both Services are integrated in our app but until now we only had instagram paid ads for our native ios-App. We now want to use ads for our native android app. The goal event for our ads is the start of a trial. We have a monthly, quarterly and yearly subscription.I'm facing the issue, that our CMO asks for AF-Events with 3 different names depending what kind of subscription trial was started. As far as I know the RC to AF Integration is insufficient for that, because each trial start irrespectibly of the subscriptiontype sends the "Trial started event" (default name: rc_trial_started_event) to AF.Therefore I need to write code, that sends these 3 Events to AF. In my current implementation I send the Events in the "onCompleted" Callback of the "purchasePackage" Method.Here is the simple Code:Purchases.getSharedInstance().purchasePackage(this, pack, new Purchas

The item you requested is not available for purchase.

I am currently using Flutter with real android device.  I recently switched to using “Google Subscription Model v2”. I followed RevenueCat instructions over here When I upload my Flutter app to Google play store internal testing, then download the app from play store to my real Android device, I am able to make  subscriptions without any problem.  On the hand, if I run my Flutter app through the command line using “flutter run”, then when I try to make subscription, I get this error: “The item you requested is not available for purchase.”.  Here is a screen shot. I am able to see the subscriptions with no problem on my screen.  I only can’t make purchase.I don’t want to deploy my app to internal testing in play store to test my code as this is so slow.  Is there a better solution. Thanks

Setting Up a perfect Listener

CollectionReference<Map<String, dynamic>> usersRef =FirebaseFirestore.instance.collection("data");Future<void> purchaseGoldPackage(Package package) async { try { await Purchases.purchasePackage(package).then((customerInfo) async { await Purchases.syncPurchases(); usersRef .doc( userID, ) .update({ 'status': 'gold', }); }); } catch (e) {}} The code above is how i set a listener for a new customer subscription,  then calling firestore to update a fieldValue “status” from ‘free’ to ‘gold’, which is how multiple devices get notified a purchase was made and the subscription is active.This works 5 out of 10 times,  which means i maybe half way there,  The issue is firestore update method dont get called  half the time, leaving user with multiple devices hanging. which means the listener i set up for firestore which updates the UI of user devices wont get triggered, forcing users to restart app to see subscription c

Staging server notifications

I’m planning two create two RevenueCat projects, one for production and one for staging, (as recommended in the quickstart), but how do people differentiate the server notifications between servers? Some of our backend APIs depend on the user’s subscription status so we save this to the respective DB.One option would be to always tie sandbox and staging together. However, this breaks as soon as we want to use a Testflight app in production.Another idea I had was to prefix the user ID with the environment name. Then have the Apple/Android server notifications go to my server, read the user ID, then proxy the request to the correct RevenueCat project, which will finally call the correct environment webhook. However, this seems like a lot of moving parts.How do other people do this?

Google Acknowledgments

Hi there! Will RC acknowledge tokens sent via https://api.revenuecat.com/v1/receipts or do RC only acknowledge tokens sent directly from google pub/sub to RC? Regarding our ticket #28392, RC doesn't acknowledge Google purchases.» Thanks for reaching out! The SDK is the entity that would handle acknowledging subscriptions - if you're not implementing the SDK and only utilizing the REST API then yes, you'll need to acknowledge transactions yourself. but this contradicts the given topic:  Could you please clarify that moment?

Purchase process in Unity3D SDK

How should purchasing process looks like in Unity3d?  In official docs Unity (revenuecat.com) we see only single function for this purpose:public void BeginPurchase(Purchases.Package package) I think it’s definetly lack of documentation. How should we obtain Purchases.Package object? Create it from new on our own? Get it somehow and store it?

Kotlin 1.4.21 Versipn

"I am working on a large, legacy Android project. I need to integrate RevenueCat into the application, but due to my Kotlin version being 1.4.21, I cannot integrate the latest versions. I tried to upgrade the Kotlin version, but then other libraries started to throw errors. The Hilt library, in particular, caused many issues. I couldn't find a way out. I'm considering downgrading the RevenueCat version, but I couldn't find which version is compatible with my Kotlin version. Could you please help me?"

Example scripts throws null reference exception in Unity3D

I’m using Unity3D 2021.3.27f1 and Revenue Cat Unity SDK 4.16.0 (also tried with 5.0.0-alpha.1). I have simple empty scene with single object called Revenue Cat with two components. 1st is the Purchases component and second is the implementation of Purchases.UpdatedCustomerInfoListener that I called RevenueCatListener. It’s just copy paste from SDK installation instructions on official docs.The problem is that on Start i’m getting two null references: 1st one when code reachs SetLogLevel function invoke and second when I try to fetch products.  I debug it and found that _wrapper that created in Purchases component is null during thins invocations. And this is very logical, because bwrapper created at Start and SetLogLevel \ FetchProducts (Offers) in docs example are at Start. So because Unity Start invocation order isn't guaranteed by default, we have wrong invocation order and null references. My question is how it’s possible that there is SUCH big problem in default examples of SDK?

iOS Swift SDK - Offering Metadata type casting errors

Recently we’ve started integrate the Offering Metadata feature. As this is a beta feature, I believe there is a minor bug in the SDK. Reproduction Steps:Add an integer property into metadata of the offering using RevenueCat dashboard (“myProperty” : 123) Try to read the the integer value using in Swift code: offering?.getMetadataValue(for: "myProperty", default: -1) The value defaults to -1 rather than 123  When I checked the SDK code, I see that the metadata dictionary returned as [“myProperty: “123”]. Then getMetadataValue<T>(for key: String, default: T) -> T function is failing to cast the value to Int even though generic value T is set to Int in above call. It is not a major issue as I can achieve casting in my code but wanted to report it here. I am using:Swift 5Xcode 14.3.1RevenueCat 4.25.0

Use with Xamarin/Maui

Hi,  Looking at using RevenueCat but looking for any feedback on using with Xamarin Forms/Maui.  I Dont see any real information on integration of this platform and was wondering if anyone has used in this configuration. Any tips on how to to implement or feedback would be appreciated.  Alternately thinking about it doing in-app and utilizing the store portals directly but this would probbably become very combersome if there were any great membership requirements.

[React-Native] How to implement addShouldPurchasePromoProductListener?

Hello, I want to be able to process subscriptions that come from App store promos.I found out that this method ‘addShouldPurchasePromoProductListener’ is should be able to process it, but I can’t find an example or doc of how to properly implement it. In my app users have to sign up first before using an app, so what if they click on that promo in the appstore before signing up, what should be the app behavior and method implementation in such case?

RevenueCat does not seem to remember the original userId set for a google account

Here's an overview of my system:My app requests a new user ID from my backend. It uses the obtained ID by passing it to the Purchases.logIn() method.When I get the original user ID from the customer info given from the login callback, it sets the original userid (UID) into its app data. Turns out when I wipe out the app data and repeat the process, the getOriginalid() method returns the same newly regenerated ID used during relogin instead of returning a different id; not considering that the same google account is logged in.I also tried changing the transfer behavior in the Dashboard, but to no avail. I want my app to obtain the original id, even when app data is reset Is there any real way that I can ensure the same user is logging in, even when App data is compromised?
