SDKs

Logs for the Flutter SDK will appear in Xcode and Android Studio rather than in the standard Flutter logs.

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 AndroidThe 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 pro

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-credentialsBefore 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 PR

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.

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.

This is the most common error from RevenueCat that can also lead to unexplained App Store rejections. Unfortunately, this error occurs when Apple's /verifyReceipt endpoint is down and unable to verify purchases. In sandbox, these errors can be fairly common since the sandbox environment is not as robust as production. In production, expect these errors less often. If your app is working in sandbox mode while testing on your own devices, this is likely an issue with the App Store. App ReviewThis issue seems to affect new apps (apps that have never been released on the App Store) during their first review more than apps that have previously been released on the App Store. Generally, the best course of action is usually to re-submit your binary or try to explain the situation to the reviewer. (Some developers have reported that they had to submit their binary over ten times before it started working as expected for the reviewer!)Just to clarify, there's nothing you as a developer or Reven
