SDKs

I am an administrator on this project, and I connected the RevenueCat extension on Stripe. The Stripe App Integration on RevenueCat was selected by the owner of the project. I am still getting this error:{ code: 7103, message: "The receipt is not valid." }whenever I try to post a call to curl -X POST \  https://api.revenuecat.com/v1/receipts \  -H 'Content-Type: application/json' \  -H 'X-Platform: stripe' \  -H 'Authorization: Bearer strp_XXXX' \  -d '{ "app_user_id": "XXX",  "fetch_token": "sub_XXX"  }'I also tried using server to server notifications, and the same error occured. What could be other possible issues for this to happen? I have not tried deleting the Stripe integration and doing it again yet.Thank you for your replies,Calda 

Hi RevenueCat team and community!How about paywalls that come alive? Animations could breathe life into paywalls and encourage users to buy. I’ve even whipped up a quick Android prototype – just take a look!SDK tech solution - use Lottie animations. This seems to be possible since all platforms (?) are covered:Android: lottie-android (https://github.com/airbnb/lottie-android, Apache 2.0) iOS: lottie-ios (

Hi,I am implementing a paywall for our iOS app. The problem is that we are two devs, so our Developer team is not an organization - which means that I need to use different bundle id and team than him. This does not effect other functions of the app, such as api calls to firebase and other, but it seems to affect Revenue Cat. When testing the paywall, do I need to have same bundle id as is set in App Store? Thanks for help!  Edit: Also, I should add that the paywall simply crashes (does not retrieve offerings), but on the revenue cat dashboard a new “customer” appears.

Hi,How i can change the bottom color (gray bar) under "restaurar compras" using Flutter?Im using the demo flutter code from docs, but don't have option to change that part.Thanks.   

I would really prefer to test and build as much as I can before having to deploy to the app stores and do the whole build process. Is there really no way to test in editor in sandbox mode?

I’m using purchases_ui_flutter 9.0.0-beta.3 with Flutter web support, and trying to get a rough idea of how much effort I should be putting into building a custom paywall, or whether I can wait for support in the SDK.Is there a rough timeline for this that can be shared, or is this not being actively developed? Thanks!

Hi there,I’m trying to get custom fonts working on a Paywall V2 within an Expo project. After following the RC instructions, things work fine on iOS - however I’m not sure what I’m supposed to do to get Android to use the custom fonts. On Android, my Paywall just defaults to a system font rather than the custom fonts (and all variants end up looking the same).My Expo config is as follows:Expo config This creates the following structure my `android` folder when I build the project - which appears right (as in, the fonts are being copied and an xml file is being generated by expo-font):Generated android folder structure from Expo

I recently started using multiple app variants workflow as described here https://docs.expo.dev/tutorial/eas/multiple-app-variants/ So basically for development and production it will have have different bundle identifier.For exampleDevelopment Build: com.yourname.stickersmash.devProduction Build: com.yourname.stickersmashI had configured everything and it worked great for com.yourname.stickersmash . So the question is to support both dev/production build with same codebase, how should I configure revenuecat? What’s the good practice?Do i need to create another app in revenuecat dashboard , everything exactly same except the “Google Play package” and “App Bundle ID” ??Note: after building with com.yourname.stickersmash.dev I’m hav

Hi there, I have an iOS app with auto-renewable subscription. Previously, we used to store the purchases in our server database and open features inside the app based on it. Now, we are trying to move to RevenueCat and opening the features using the below code instead of relying on our server side subscription status.CustomerInfo.entitlements["Pro Access"].isActive After user update the new version with RevenueCat, will you get the active subscription automatically from Apple Receipt and enable entitlements or should we call syncPurchases programmaticaly so that you will enable entitlements based on it? Please advise, Thank you.

Hi! Is there an endpoint available that allows me to only get my active subscribers?I was only able to find this endpoint, which just returns all customers:https://api.revenuecat.com/v2/projects/{projectId}/customersI saw this old thread where this wasn't possible, but it would be great if it's been added since then.Furthermore, I looked through the docs here, but wasn’t able to find an endpoint that just returns my active subscribers / free trials.https://www.revenuecat.com/docs/api-v2#tag/Entitlement/operation/detach-products-from-entitlement

I’m using RevenueCat Experiments and would like to clarify how targeting rules interact with experiment variants. I’ve reviewed the documentation here: RevenueCat Targeting FAQ, which states that experiments are evaluated before custom targeting. However, based on my testing, it appears that RevenueCat respects targeting rules first before applying any experiments.My setup: I’ve defined a custom subscriber attribute called subscription_type, which can be either "Free" or "Premium". For the appLaunch placement, I’ve added the following RevenueCat targeting logic: If subscription_type == "Free" → show a paywall. If subscription_type == "Premium" → no paywall/offering should be shown.

Hi all In my app I am able to make purchases. That is working fineHowever the users who have not yet purchased but interacted with the app including going to the paywall are not showing up under customs in RevenueCat.I am using Flutter flow.What could I be doing wrong?

The new Customer Center doesn’t seem to be showing the userID. In the previous version, the userID was visible in the Purchase History. However with the new version it’s nowhere to be found. I can confirm this on both debug and production builds (not sure if these are supposed to be different?).I’m looking at iOS platform and on latest SDK 5.28.1 version.I assumed this was removed on purpose in the new Customer Center so I was just about to add it to my app manually. But after seeing it existed in the demo from the June 2025 launch party, I am not sure if there’s something I have to do on my side to show the userID in the Customer Center? My user’s all have anonymous ids.This is how it looks like: 

I need to display the subscriptionPeriod and the price of the currently active subscription directly within the app.My app uses anonymous user IDs (no login or authentication), and I don’t have a backend server involved.What is the best way to retrieve and display this information using the RevenueCat React Native SDK?

I’m trying to follow the docs for the capacitor purchases plugin. I’m migrating my codebase from the awesome-cordova-plugins approach I used with capacitor 2. Incidentally, docs are not entirely clear as sometimes there’s no capacitor example (only cordova). Anyway, my issue isIf I use one of these ...const customerInfo = await Purchases.getCustomerInfo();Purchases.getCustomerInfo().then((customerInfo) => {Then use this ... it tells me there’s no entitlements property …customerInfo.entitlements.activeBut if I double up the ‘customerInfo’ then it doesn’t complain …customerInfo.customerInfo.entitlements.activeNote that these issues are showing up in VSCode editor … I haven’t converted all the code yet, so nowhere near actually building/running this.

Hi RevenueCat team,I'm experiencing an issue with the relative_discount calculation in my paywall.Setup- Package 1: 6 months subscription at €59.99- Package 2: 12 months subscription at €55.00 (with 8% OFF badge)Expected behaviorThe annual package should show ~54% discount compared to 6-month package:- 6 months annualized: €59.99 × 2 = €119.98/year- 12 months: €55.00/year- Real discount: (119.98 - 55) / 119.98 = 54.17%Actual behaviorPaywallView displays "8% OFF" which is incorrect.Questions1. How is relative_discount calculated exactly?2. Is this comparing against a different reference price?3. Should I configure something specific in my offering setup?Environment- purchases_ui_flutter: ^8.10.1- Platform: Android/iOSAny guidance would be appreciated! 

I am trying to build my app with Xcode 26 beta 1. RevenueCat is generating errors:For many functions, I’m getting this error.“Concurrency is only available in iOS 13.0.0 or newer” Here is an example of the code in Obsoletions.    func paymentDiscount(for discount: SKProductDiscount,                         product: SKProduct) async throws -> SKPaymentDiscount {        fatalError()    } I am using RevenueCat 4.43.3Is there a way I can avoid these errors - I am not ready to move to RC 5.x yet.My code supports iOS 16 or later.

Hi all, I am trying to set up a new react native app and having trouble with this err: [Error: There is an issue with your configuration. Check the underlying error for more details. There's a problem with your configuration. None of the products registered in the RevenueCat dashboard could be fetched from App Store Connect (or the StoreKit Configuration file if one is being used). More information: https://rev.cat/why-are-offerings-empty]I had this working just last week (paywall was showing up, products fetched properly etc.) but it suddenly stopped working. I have not changed anything in my revenuecat setup, I haven’t changed anything in my app store connect or revenue cat setup (I’ve checked revenuecat audit logs, nothing changed in last 3 weeks). The only potential issue was there was a new app developer agreement for free apps, so I signe

Hey team - getting this crash on Xcode 26b1 (17A5241e) running on any iOS 26 simulators. I’m on the new v5.28.0 SDK. I can’t repro this in a sample project, otherwise I would’ve posted this to Github as an Issue, not sure if it’s something in my project setup, etc.  Things I’ve tried:I commented out any other use of the RC SDK to make sure there wasn’t some race condition happening I’ve tried changing my deployment target to iOS 26 (instead of iOS 17 where I am now) I’ve tried some of the other configure functions including the config builder one, they all crash the same It’s affecting all iOS 26 sims, doesn’t crash on iOS 18 sims I simplified my AppDelegate to the following and still getting the crash (it crashes with a real API key or a fake one in there): import RevenueCat@mainclass AppDelegate: UIResponder, UIApplicationDelegate {

Hi,Thanks for your blog post: Converting a Paid iOS App to Subscriptions. It was very helpful! I have a few follow-up questions: Is all the code and information in the post still up to date after a few years? Regarding the syncIfNeeded function: it checks the info returned from RevenueCat, and if that fails and a receipt exists, it attempts to sync. But what happens if the receipt doesn't exist, or syncing isn’t sufficient? Is that a possible scenario? How should we handle users in that situation? In such cases, should we fall back to calling restorePurchases, which might trigger the system sign-in prompt? The article doesn’t mention this. Also, I noticed that appStoreReceiptURL is now deprecated, and Apple recommend

I'm running into an issue when using the PaywallViewControllerDelegate with the RevenueCat iOS SDK version 5.22.2.I’m presenting the paywall manually using the following code:extension AppPaywallBuilder { func build() -> UIViewController { let viewController = PaywallViewController(offering: subscriptionManager.offering) viewController.delegate = self viewController.modalPresentationStyle = .fullScreen return viewController }}extension AppPaywallBuilder: PaywallViewControllerDelegate { func paywallViewController(_ controller: PaywallViewController, didStartPurchaseWith package: Package) { print("aaaa") } func paywallViewController(_ controller: PaywallViewController, didFinishPurchasingWith customerInfo: CustomerInfo) { print(

Hi all, I have a little question about localizing price strings. In English the variable  {{ product.price_per_period_abbreviated }} returns $9.99/mo which is perfect but I can’t find in the docs what variables are localized so would that translate automatically for users in other locals? or should I provide the abbreviation myself (in this case Chinese) {{ product.price_per_period }}/月Thanks so much

With macOS Tahoe released today, I wanted to see how my app ran on it. But I ran into a compile error when using the RevenueCate Flutter package:Swift Compiler Error (Xcode): Protocol 'StoreKit2PurchaseIntentType' requires 'id' to be available in iOS 16.4 and newerbut I wanted to post my issue here to get the ball rolling on using RevenueCat with the new OS 26 versions.This error was within the StoreKit2PurchaseIntentListener.swift file.I am using this purchases_flutter: ^8.10.1

I want to be able to change the trial period on a product, or the grace period, and I’m realizing none of this is editable in the RevenueCat dashboard. Does it have to be set when the product is created, and then I need to create new products every time I want to make a change?  I ask because: We have a field in our DB that stores if a customer is annual or monthly (which are two products at the moment), and we are getting this info from the customer info in the Web SDK. The only place there we can identify the subscription duration is from the product name. But, if we need to change product names regularly to change things like trial period, we need to make code changes on our side every time. It’d be nice if we either could modify products, or if the Web SDK could return duration in the customer info.
