Paddle offers a comprehensive payment processing API with subscription management, webhook systems, and compliance features built for SaaS businesses. Our Paddle boilerplates implement the provider's complete API suite—from Payment Intents to subscription schedules—with secure webhook handling and Paddle-specific features like tax calculation and dunning management.
Paddle boilerplates integrate the provider's latest API version with proper error handling, idempotency keys, and retry logic. They implement Paddle-specific webhook signature verification for secure event processing, use Paddle's subscription APIs for lifecycle management (trials, upgrades, cancellations), and leverage Paddle's compliance features like SCA authentication and tax calculation. The implementation handles Paddle's specific payment flows and error scenarios following provider best practices.
Browse our collection of 8 Paddle boilerplates to find the perfect starting point for your next SaaS project. Each boilerplate has been carefully reviewed to ensure quality, security, and production-readiness.
Paddle boilerplates implement the provider's complete API suite including checkout sessions, subscription lifecycle management, customer portal, webhook event handling, and invoice generation. They use Paddle's latest API version with proper error handling, idempotency keys, and retry logic. The integration includes Paddle-specific features like payment intents, setup intents, subscription schedules, and tax calculation APIs.
Paddle webhooks are verified using the provider's signature validation to prevent spoofing attacks. The boilerplate includes webhook endpoints with proper Paddle signature verification, event type filtering, and idempotent event processing to handle duplicate deliveries. Events are processed asynchronously with retry logic, and the implementation handles Paddle's specific webhook events like subscription updates, payment failures, and customer changes.
Paddle 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 Paddle'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.
Paddle boilerplates implement the provider's smart retry logic and dunning management. They handle Paddle's specific failure scenarios including insufficient funds, expired cards, and authentication failures. The system sends automated email notifications through Paddle's webhook events, implements grace periods before downgrading service, and provides customers with update payment method flows using Paddle's hosted UI or API.
Paddle 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 Paddle'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 Paddle, never touching your servers.
