Testing Web Purchases
In contrast to mobile app stores, there is no intermediary between you and the customer, and no App Review before you start charging customers money. Therefore, you should make sure that you have properly tested your implementation in sandbox mode before shipping your web subscriptions.
Testing a Web SDK integration
You can use Stripe's Test Mode to test your Web Billing integration.
If you use the Web Billing sandbox API key, Stripe's test mode will be used automatically, and you can use one of Stripe's test cards to make purchases.
Testing Web Paywall Links
RevenueCat provides a separate sandbox link for testing, which should not be shared with customers.
The sandbox URL is automatically configured to use Stripe's test mode, and should be used with Stripe test cards.
Testing Wallet Payment Methods
For both Apple Pay & Google Pay, you can use real payment cards in sandbox. Stripe configures both payment methods in a test mode, no real transactions are made.
Subscription Schedules in Sandbox
Sandbox subscriptions renew faster than actual subscriptions to facilitate testing. They can renew a maximum of six times. At that point, the subscription will be automatically cancelled.
The following table lists the sandbox renewal periods for subscriptions of various durations. These times are approximate, and you may see small variations. To ensure accuracy, check the current status after each subscription expiration.

| 1 day (P1D) | 5 minutes |
