They implement In-App Purchases-specific webhook signature verification for secure event processing, use In-App Purchases's subscription APIs for lifecycle management (trials, upgrades, cancellations), and leverage In-App Purchases's compliance features like SCA authentication and tax calculation. The implementation handles In-App Purchases's specific payment flows and error scenarios following provider best practices.

In-App Purchases boilerplates implement the provider's complete API suite including checkout sessions, subscription lifecycle management, customer portal, webhook event handling, and invoice generation. They use In-App Purchases's latest API version with proper error handling, idempotency keys, and retry logic. The integration includes In-App Purchases-specific features like payment intents, setup intents, subscription schedules, and tax calculation APIs.
In-App Purchases webhooks are verified using the provider's signature validation to prevent spoofing attacks. The boilerplate includes webhook endpoints with proper In-App Purchases signature verification, event type filtering, and idempotent event processing to handle duplicate deliveries. Events are processed asynchronously with retry logic, and the implementation handles In-App Purchases's specific webhook events like subscription updates, payment failures, and customer changes.
In-App Purchases boilerplates include complete subscription lifecycle management using the provider's API: plan creation, subscription initiation, proration handling for upgrades/downgrades, trial period management, and cancellation flows. The implementation handles In-App Purchases's specific billing cycles, metered billing (if applicable), and subscription schedules. Database models sync subscription status, billing periods, and feature entitlements in real-time through webhooks.
In-App Purchases boilerplates implement the provider's smart retry logic and dunning management. They handle In-App Purchases's specific failure scenarios including insufficient funds, expired cards, and authentication failures. The system sends automated email notifications through In-App Purchases's webhook events, implements grace periods before downgrading service, and provides customers with update payment method flows using In-App Purchases's hosted UI or API.
In-App Purchases boilerplates leverage the provider's tax calculation APIs (Stripe Tax, Paddle's automatic tax handling, etc.) for automatic sales tax, VAT, and GST calculations based on customer location. They implement In-App Purchases's compliance features including SCA (Strong Customer Authentication) for European payments, PCI DSS compliance through hosted payment pages, and proper invoice generation with tax line items. All card data is handled by In-App Purchases, never touching your servers.
