Hey,is there any update for changing the language programmatically especially on Android?Currently everything is only in english using paywalls even when there is different device language.

We have integrated RevenueCat Android SDK with our native Android app. Almost all of the purchases are handled as expected but sometimes it doesn’t. I observed very few customers have been facing the below PurchaseError.PurchasesError(code=PurchaseInvalidError, underlyingErrorMessage=Couldn’t find existing purchase for SKU: {subscription_id}, message=‘One or more of the arguments provided are invalid.’) I read the source code of the purchases-android SDK, and if my understanding is correct, this error occurs when it fetches purchase history via BillingClient and there’s no record that matches with the subscription ID set by `PurchaseParams::oldProductId({subscription_id})`.I believe it is NOT something like network issue or service unavailable error, etc, since if there’s an issue between client and Google billing system, it should NOT go through the code that emits the PurchaseError in question. (should go onError route

Hello there,I’m creating multiple whitelabel apps for several platforms, clients etc and would love to use RevenueCat for everything subscription-related. I was checking out the RevenueCat Rest API but it doesn’t seem like I can (fully) create projects, apps and basically everything programatically through the API. Did I look into the wrong place or is there just no support for this? And maybe somebody knows if this is on the roadmap? All the best and thanks!

Hi RevenueCat Team, I wanted to clarify how Monthly Tracked Revenue (MTR) is calculated for annual subscriptions. For example, if I sell a $12/year subscription and the user pays the full $12 upfront, does RevenueCat:1. Count the full $12 in MTR for the month when the transaction happens?2. Or does it amortize the revenue over 12 months, adding only $1 per month to MTR? Additionally, how does this apply to lifetime purchases? Are they also amortized over a specific duration, or do they count fully in the transaction month? Looking forward to your insights!

Hi there,We have a multi-tier concept similar to this:Tier 1 - access to 1 course onlyTier 2 - access to 2 courses onlyTier 3 - all access to coursesAnd each tier will have 1 month, 6 month and 12 month variations.Users can have only 1 subscription at the same time, and for example user can go from "Tier 1, 1 month" to "Tier 3, 6 months" subscription. So we have set up App Store Connect with the following:- Only 1 subscription and all 9 variations created under the same subscriptionBut what about Google Play Console? Should I create one subscription and create 9 base? Or 3 different subscriptions with each of them having 3 variations (1 month, 6 months and 12 months)?Also, should I create 3 entitlements or 1 entitlement in RevenueCat?

the story: I was integrated in-app purchase directly with apple, but sometimes i got duplicate transactions, i don't know why so i switched to using RevenueCat. Below is the problem i got when using RevenueCat.the context: customer 46611 made a purchase with package1 but the webhook was duplicated. the first webhook request was called to handle package1, the second one was called with package4 infonote: the second transaction was created before using RevenueCat SDK. my event type is Non renewing purchasequestion: Why do duplicate webhooks happen, and how can I avoid them? 

Hi, I was rejected from app store with the following reason: Guideline 2.1 - Performance - App CompletenessIssue Description The app exhibited one or more bugs that would negatively impact App Store users. Bug description: we were unable to proceed with subscription purchase as we encountered an error when we tapped on 구독 신청 button. My revenue cat integration is currently not working on iOS but i am assuming that this is because my subscriptions on app stores aren’t approved.   (Error I get when i run `presentPaywall()` with sandbox apple account)Error 23

I was thinking about uploading my React-Native Android App to Huawei AppGallery.I use IAP using RevenueCart with iOS and Google and was wondering, whether Huawei support is already available / planned / not possible.Thanks in advance!

I’m experiencing an issue with my iOS subscription offerings in RevenueCat. When users tap on subscriptions in my app, the pricing displayed is incorrect – for example, it shows INR 1500 for the yearly plan and INR 12000 for the monthly plan, which do not match the values configured in App Store Connect. Here’s what I’ve checked so far:• API Key (.p8):My API key was uploaded about 8–9 months ago, and according to my RevenueCat dashboard, it is still valid and active.• Product IDs:I’ve verified that the product identifiers in RevenueCat exactly match those in App Store Connect. The products are properly set up, and each subscription is marked as “Ready for Sale.”• Bundle ID:The bundle identifier in RevenueCat matches the one in my App Store Connect account.• Other Checks:I’ve ensured there are no pending Apple agreements or issues in the Agreements

How do I process pending transactions using revenue cat? When a transaction is pending, does revenue cat handle it automatically or do I have to do something special? Can someone help?

I’m using the following to purchase inapp using revenue cat  if let offerings = offerings { for offering in offerings.all { let packages = offering.value.availablePackages if let indexOfItem = packages.firstIndex(where: { $0.storeProduct.productIdentifier == productId }) { let package = packages[indexOfItem] Purchases.shared.purchase(package: package) { (transaction, customerInfo, error, userCancelled) in if customerInfo?.entitlements["sumizeit_premium"]?.isActive == true { Task { await self.purchase (vc: vc, productId: productId, product: productId) } } } } } } Is that the correct code to make purchases? When I use that code I’m able to purchase, but apple server

My understanding is that while there is a concept of sandbox versus production purchases, there is no concept of a development versus production users. And since we can’t filter by custom user attributes, stats that involve factoring in the total number of users, like subscription rate, will be off in charts and experiments.Off the top of my head, some solutions might be:Mock RevenueCat outside of prod. Delete development/test users when I’m done with them. Accept that some metrics will be off. Perhaps use a separate analytics service for those.Is my understanding correct? And is there an official recommendation for how to handle this?

I’m curious to see what the RevenueCat folks, as well as other users, make of Apple’s just-announced change in policy regarding directing users to make purchases on the app’s website: https://developer.apple.com/support/storekit-external-entitlement-us/ I think that this change has something to do with recent anti-trust lawsuits, possibly involving the Fortnite people.  But, if you read through the article, it sounds like Apple is not only making a lot of demands on how to make use of the new policy, but they are also expecting developers to continue giving them a cut of the sales, including the ones made on the app’s website, if users clicked a link to the site from within the app (although I don’t know how they plan to enforce that). Thoughts?

I have two customers showing up in my sandbox customer list but I can’t delete them.When I click on them, they don’t pull up but they still show up in the list.How do I contact support to help me delete these customers that refuse to go away?Another post says it could take up to an hour but it’s been over a day.   

We’ve integrated Customer Center (Flutter SDK 8.6.1) in our Flutter app, and about 40% of the time the app crashes when it’s invoked. Also, the Cancel subscription function doesn’t work (at least not with Sandbox purchases). It just keeps saying Cannot Connect.

I want to generate codes that offer a free year of subscription and use Web Billing for this. Is this possible?

What would be the best way to give the user a free month if they are already had a subscription? We want to implement a referral reward system in our app and the user can redeem multiple free months separately so we would want them to stack if possible.I’ve seen that both iOS and Androids have Promo Codes we could give to users but those seem to be for new users:https://docs.revenuecat.com/docs/ios-subscription-offershttps://docs.revenuecat.com/docs/android-promo-codesI did see that RevenueCat has an API to extend this as well, but wasn’t sure how that would work. Is RevenueCat that one that tells Apple or Google to charge for the subscription again? If not does it tell Apple or Google to not charge until a cert

Is there a way to add user info when they purchase, like email for example?

is there a way to show dynamic text in my paywall ? For example when user selects the yearly plan they see the text "START MY 7-DAY FREE TRIAL" and for monthly plan they see the "START MY JOURNEY" in the CTA button.Currently when the user selects either of the pricing plan, they see “START MY JOURNEY”

Greetings. We have two account types; one is for regular users (A) and one is for companies (B), and respectively have two subscription groups. Regardless of what transfer configuration I pick in the RC settings, switching account and purchasing a subscription will either transfer subscriptions from account type A to account type B (Transfer to new app user id) or subscriptions made in type B will always be set to account type A (Keep with original app user id).How can I resolve it? Each of these subscriptions cost and behave differently.

Hello RevenueCat,I can see some similar topics, but i didn’t understand clearly the solution. As there are multiple topics on Stack Overflow, discords and more I think no one can find easily a clear solution.ContextI’m inside my test app using the SandBox mode. I’ve set the option ‘Keep with original App User Id’ because I don’t want to let an user  the ability to transfer to someone else his subscription. All users have an account and I well use the `Purchases.configure()` and or  `Purchases.logIn()` methods to handle that. I’ve 2 google accounts on my Android Emulator (ex: bob-example@gmail.com and alice-example@gmail.com). My app have a subscription mode to let creators access some premium contents. ScenarioI open the app and I login to bob-example@gmail.com, then I open

I don’t understand how this is possible. I have got my ios app(flutter) published in app store some time ago. Before I tried some purchases with sandbox account (german). And they are listed in sandbox purchases without issues. I also had some production purchases as well. Then it stopped.Today when I check my sandbox account, I see some american accounts made in app purchases. It is definitely not me as I have only 1 sandbox account and it is german account.Firebase also reports in_app_purchase events.I thought RC detects prod vs debug environments.Am i overlooking something? Did anyone experienced something like this before?I build my app for app store with: flutter build ipa --release 

I am trying to implement the new RC v2 paywall into my app without bothering my usual developer friend. I can get the paywall to load perfectly in xcode preview but when I try running in the simulator I keep getting an error message stating that “purchases has not been configured”. Any ideas?  

Hello,url = f"https://api.revenuecat.com/v2/projects/{project_id}/customers/{customer_id}/active_entitlements"The above URL returns a list of active entitlements for my sandbox environment which is great - I noticed for some of the other endpoints there is an “environment” field which looks to toggle between sandbox/production - does the above endpoint have an equivalent ?Couldn’t find any reference on how to distinguish between the sandbox/production data for this particular endpoint - there was mention of their being a “sandbox” flag but I can’t seem to find it.Hope that makes sense!
