How to reset purchases when users switch Apple accounts

I noticed that when a user bought an IAP (no-consumable) on a macOS device, and then switched to a different Apple account, the new account still had access to pro features. I tried restarting the app and clicking the restore purchases button (which called `Purchases.shared.restoreTransactions`) but they didn’t help. I think the cause is Apple doesn’t refresh receipts for apps when a new account is signed in. I’m wondering if that is expected and what is the best practices to deal with that (ex should we just ignore those cases or there is a method to refresh receipt explicitly (and if that’s the case, should we invoke that method on every launch?)).

why are sandbox tests using observer mode not showing up in RC?

Configured an iOS app for observer mode to run alongside our existing iOS storekit implementation. After two subscription tests in Sandbox, no data appears in RC. I seem to be missing something, but have followed the docs I find regarding observer mode. I can see through device settings>app store>sandbox that the subscription test is active and my app behaves as such, so I know the sandbox transactions exist. Thanks.

Ionic's Purchases plugin can't get any entities

So I'm using the @ionic-native/purchases plugin for setting up in-app subscriptions. The only plugin-related code I have is this.purchases.setDebugLogsEnabled(true); this.purchases.setup(environment.purchasesAPIKey, appUserID); on the app's initializing. And then in another component: this.purchases.getPurchaserInfo().then((purchaserInfo) => { console.log('purchaserInfo:', JSON.stringify(purchaserInfo)); }); this.purchases.getOfferings().then((offerings) => { console.log('offerings:', JSON.stringify(offerings)); }); this.purchases.getProducts(['product1_test']).then((products) => { console.log('products:', JSON.stringify(products)); }); console.log('appUserID:', this.purchases.getAppUserID()); All the methods return empty lists / objects, e.g.: offerings: {"all":{},"current":null} Even though the underlying request that I found in Android Studio's Profiler gives back proper offerings data: { "current_offering_id": "default", "offerings": [ { "description": "Standard Set of Packages", "

How can I implement Promoted in-app purchase?

Hi there, I’ve been searching for a few days how to implement promoted in-app purchases in my app with RevenueCat. My environment: RevenueCat SDK version is 3.12.2 iOS platform iOS 14 Xcode 12.5.1 Research I’ve found this question in Github. I’ve also read the SDK reference. Question Now, SwiftUI apps launch using a custom struct that conforms to the App protocol, so there is no AppDelegate file anymore. My App struct is something like that: @mainstruct SimoleonApp: App { init() { Purchases.configure(withAPIKey: "KEY") } var body: some Scene { WindowGroup { ContentView() } }} My question is, where do I have to place the following function to support promoted in-app purchases? func purchases(_ purchases: Purchases, shouldPurchasePromoProduct product: SKProduct, defermentBlock makeDeferredPurchase: @escaping RCDeferredPromotionalPurchaseBlock) { makeDeferredPurchase { (transaction, info, error, cancelled) in if let purchaserInfo = info { handlePurchaserInfo() } }} Thank you.

How upgrades/downgrades work on iOS and Android

Note that developers (you) cannot change a customer's subscription directly. The app stores do not allow developers to upgrade or downgrade a subscription on behalf of a customer. Only a customer can change their subscription. iOS There are no code changes required to support upgrades, downgrades, and crossgrades for iOS subscriptions in your app. A customer can upgrade, downgrade, or crossgrade between subscriptions as often as they like. According to Apple , when a customer changes their subscription level, access to the new product can vary depending on the new product: Upgrade. A user purchases a subscription that offers a higher level of service than their current subscription. They are immediately upgraded and receive a refund of the prorated amount of their original subscription. If you’d like users to immediately access more content or features, rank the subscription higher to make it an upgrade. Downgrade. A user selects a subscription that offers a lower level of service than

"There is already another active subscriber using the same receipt." error occurs when trying to purchase a non-renewable product

As the title suggests, I am having trouble purchasing a non-renewable product on my app. Here is an overview of my current setup: Flutter app (with products that can be purchased via app store or play store) Web app (with the same products that can be purchased via Stripe) Server (acts as the backend, is used for authenticating users on login) The non-renewable product is specific to each user. In other words, if user A logs on to the app and purchases the product, then any privileges associated with that non-renewable product will be granted to user A. Then, if user A logs out of their account and user B logs on to the app using their own account on the same device, user B should not have access to those privileges. In order to test the scenario mentioned above on my Flutter app, these are the steps I took: Log on to app using account A Purchase non-renewable product Verify that privileges are granted Log out of app Log on to app using account B Purchase non-renewable product Verify t

Customers being charged, but purchase does not show up in RevenueCat

A common issue in my app has been that 1: The customer got charged 2: The purchase does not reach RevenueCat 3: The customer reaches out to support. 4: I ask them to restore purchases and everything is synced correctly. I did read the article here: But it doesn’t contain much details on how to detect the error. I also reached out to support about this issue and got a pretty unhelpful response from support (and did not get any comment on my follow up emails). “Restoring transactions is our recommendation here. Unfortunately Apple and Google's in-app purchase process makes this a necessity. Beyond that, we don't have any general recommendations.…... Are users are complaining about not getting an entitlement after purchasing? Maybe an action item here is to show UI recommending the user to restore purchases if no entitlements are detected after a purchase. You can get creative here but outside of restoring purchases there's not much else to do..” Is there a way to detect if the user purch

allowSharingAppStoreAccount deprecated -> Configure in dashboard... but where?

Hi, I’m new to RevenueCat and I’m in the process of refactoring a piece of code using the ‘allowSharingAppStoreAccount’ function. The documentation says: allowSharingAppStoreAccount DEPRECATED Configure behavior through the RevenueCat dashboard instead. I’ve looked everywhere in the dashboard, but can’t find any setting that would seem to relate to this? Also, I’m unsure exactly what this function does: is it for instance in case someone creates several accounts in the app with, say, different email addresses, but has a single App Store account? Thanks to anyone who takes the time to help!

unable to track error in React Native

I’m following the supplied examples and was able to list packages and buy one product. Although the process do not reach the end because of a raised error, but the error is very general, and not clear at all. Also it does not have any error code as it was supposed to according to the docs here (https://docs.revenuecat.com/docs/errors#android-errors). My Code: try { const offerings = await Purchases.getOfferings(); if (offerings.current.lifetime !== null) { const currentOffering = offerings.current.lifetime; const { purchaserInfo, productIdentifier } = await Purchases.purchasePackage(currentOffering); if (typeof purchaserInfo.entitlements.active[ENTITLEMENT_ID] !== 'undefined') { console.log("Purchase Success"); } }} catch (e) { if (!e.userCancelled) { console.log(e); }} Let me be clear that the native android purchase popup is correctly shown int the device (real device, not simulator), and the process is succeed by Google.

What format is PurchaserInfo?

Using RevenueCat for Unity, I am receiving json return values from RC in response to GetOfferings, RestorePurchases, etc. They usually come in the form of a PurchaserInfo object. I can’t find any documentation anywhere on the exact details of what is in this object. Specifically the date values look like this: "originalPurchaseDate":1626733276,"latestPurchaseDate":1626733275 EDIT: Ohhh, these Ints are just the values shown by the XCode debugger, in C# the object contains dates in DateTime type. I was looking at the raw json data and wondering what those date numbers stood for. Still trying to find in-depth docs for the C# Type PurchaserInfo, what all is in it and how it behaves. What are these integers and how does one make them into a date? Does any documentation exist detailing the return values from RC calls? Thanks!

Purchases.init does not update when called 2 times.

Background: In my flutter app it is possible for a user to sign out and another user to sign in without restarting the app. To support this feature the app calls Purchases.init whenever a user logs in. If the transition is non-sub to sub this works as expected IE the latter user sees their subscription. But this does not work if transition is sub to non-sub. In this case RC fails to update to non-sub and the non-sub user appears to have a subscription until they restart the app and the sub is gone. Fix: reset all data when Purchase.init is called.

Why are offerings or products empty?

Check out our new and improved walkthrough guide! If you're still testing in sandbox, it's most likely a configuration issue that's preventing the products from being retrieved from Apple/Google. Your product identifiers are set in RevenueCat, but the actual products that your users purchase can only be retrieved directly from Apple/Google. Because this communication happens between your app and the stores, RevenueCat doesn't have any visibility into the API requests, however there are some common requirements to go through. iOS and Android The product identifier set in RevenueCat matches exactly with the store You're testing on a physical device and not a simulator The bundle ID in Xcode [iOS] or package name [Google/Amazon] match what's in App Store Connect or Google Play/Amazon Developer console. If you have both development and production environments for your app, be sure to double check you are using the correct bundle IDs [iOS] or package names [Google/Amazon]. You’ve set the pr

Invalid Play Store credentials errors

If you're receiving an error message "Invalid Play Store credentials" when attempting to make a purchase on Android, it's due to the service credentials that you've added to RevenueCat being invalid: https://docs.revenuecat.com/docs/creating-play-service-credentials Before you go and generate new credentials, it's important to know that it can take anywhere from 24-48 hours for Google to propagate your service credential access after they're created. There are a few places to check your configuration. You have followed the configuration steps outlined in RevenueCat’s documentation . Your Google Play package in your RevenueCat app settings page matches what’s shown in your build.gradle file. You have inputted the correct JSON keys from step 2e without any whitespaces. Your JSON should look like the following: {"type": "service_account","project_id": "your_project_id","private_key_id": "your_private_key_id","private_key": "-----BEGIN PRIVATE KEY-----YOUR_PRIVATE_KEY_CONTENT-----END PRIVA

"The device or user is not allowed to make the purchase" error

This error could be due to a few reasons. Try the following troubleshooting steps: Make sure your device/emulator is completely updated. Try running on device. Sometimes the emulator glitches out and it must be restarted. Overall, testing on device is more reliable. Restart your device/emulator. Make sure you're logged in with a Google account. If you're running on an emulator, make sure it has Google Play installed.

Apple will randomly generate billing errors for auto-renewable subscriptions in sandbox. This is expected behavior; it's part of Apple's sandbox environment so that you can test for the billing error case.

App not working in iOS simulator

It is highly recommended to test on a real device. This is because StoreKit is flaky in iOS simulators - it will randomly fail when fetching products, offerings, etc. Learn more on testing purchases in sandbox in our documentation.
