Testing purchases in App Store Sandbox

πŸ‘

This section assumes you've followed our Quickstart section of our Getting Started guide to install and configure our SDK.

Create a sandbox test account

In order to test your purchases, you'll need a sandbox test account. You can create test accounts from your App Store Connect dashboard > Users and Access > Sandbox Testers.

If you need help, you can refer to Apple's guide on creating sandbox testers here.

πŸ“˜

Valid email required for sandbox accounts

Keep in mind you'll need to create sandbox accounts with valid emails that you can verify you own.

Add the sandbox test account to your device

Even for sandbox purchases, you'll need to test on a real device. Starting in iOS 12, you're able to add a sandbox account to your device without having to sign out of your iTunes account.

On iOS 12 or greater, navigate to Settings > [Your Account] > iTunes & App Store > Sandbox Account.

On iOS 13 or greater, navigate to Settings > iTunes & App Store > Sandbox Account.

Add the sandbox account credentials that you previously created. (The sandbox account credentials won't appear until you've made a purchase using a sandbox account in a development build.)

Add your sandbox account under iOS settings to streamline testing

πŸ“˜

If you do not see the option to add a sandbox account under iOS settings, make a sandbox purchase in your app. Apple will show a popup to enter login details, then you will see your account in iOS settings.

🚧

StoreKit does not work in the simulator

StoreKit's stability in the simulator has been historically flaky, resulting in random bugs when fetching products. Make sure to test on a real device.

Make a purchase

Build and run your app on your device. When you attempt to make a purchase, you may be still be prompted to sign in with the sandbox account you just created.

πŸ“˜

Apple may prompt you to sign into an iTunes account whenever you make or restore a purchase. When using Purchases, this could only happen when you call .makePurchase or .restoreTransactions. Developers don't have control over the type of prompt that is shown (Touch Id, password, etc.)

Verify transaction appears in dashboard

After a purchase is successful, you should be able to view the transaction immediately in the RevenueCat dashboard. If the purchase does not appear in the dashboard, it's not being tracked by RevenueCat.

πŸ“˜

Make sure Sandbox Data is enabled

Make sure the the View Sandbox Data toggle is enabled in the navigation bar.

πŸ“˜

Sandbox receipts are transferred between users

If a user uploads an expired sandbox receipt (when making a purchase or restoring purchases) that had previously belonged to a different user, the receipt is transferred to the new user. This behavior is in place so you don't need to create a new sandbox user in App Store Connect for every App User Id you wish to test with.

Sandbox specific logic

If latest subscription has expired in sandbox and a new App User Id attempts to purchase or restore, RevenueCat will move the purchases around between users. This logic exists to simplify sandbox testing so you don’t need to create new sandbox users all the time to avoid hitting RECEIPT_ALREADY_IN_USE errors frequently.

Working with subscriptions

In the the sandbox environment, subscription renewals happen at an accelerated rate, and auto-renewable subscriptions renew a maximum of six times per day. This enables you to test how your app handles a subscription renewal, a subscription lapse, and a subscription history that includes gaps.

Because of the accelerated expiration and renewal rates, sometimes not all renewals are reflected in the RevenueCat customer dashboard.

Deleting test users

When testing, it may be helpful to delete a customer and all their receipts from RevenueCat to simulate a new installation. You can delete a specific user from the customer dashboard in RevenueCat. See our docs on deleting users for more information.

πŸ“˜

Make sure to log out of the sandbox user on your testing device

Deleting the user from RevenueCat doesn't delete the user's purchase history with Apple. It only deletes the user's receipt and metadata from our servers. That means making or restoring purchases will restore those purchases with RevenueCat. To simulate purchasing as a completely new user, make sure to log out of the sandbox account on your device and create a new one.
