Superwall boilerplates implement the provider's complete API suite including checkout sessions, subscription lifecycle management, customer portal, webhook event handling, and invoice generation. They use Superwall's latest API version with proper error handling, idempotency keys, and retry logic. The integration includes Superwall-specific features like payment intents, setup intents, subscription schedules, and tax calculation APIs.
Superwall webhooks are verified using the provider's signature validation to prevent spoofing attacks. The boilerplate includes webhook endpoints with proper Superwall signature verification, event type filtering, and idempotent event processing to handle duplicate deliveries. Events are processed asynchronously with retry logic, and the implementation handles Superwall's specific webhook events like subscription updates, payment failures, and customer changes.
Superwall 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 Superwall'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.
Superwall boilerplates implement the provider's smart retry logic and dunning management. They handle Superwall's specific failure scenarios including insufficient funds, expired cards, and authentication failures. The system sends automated email notifications through Superwall's webhook events, implements grace periods before downgrading service, and provides customers with update payment method flows using Superwall's hosted UI or API.
Superwall 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 Superwall'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 Superwall, never touching your servers.
