PayPal offers a comprehensive payment processing API with subscription management, webhook systems, and compliance features built for SaaS businesses. Our PayPal boilerplates implement the provider's complete API suite—from Payment Intents to subscription schedules—with secure webhook handling and PayPal-specific features like tax calculation and dunning management.
PayPal boilerplates integrate the provider's latest API version with proper error handling, idempotency keys, and retry logic. They implement PayPal-specific webhook signature verification for secure event processing, use PayPal's subscription APIs for lifecycle management (trials, upgrades, cancellations), and leverage PayPal's compliance features like SCA authentication and tax calculation. The implementation handles PayPal's specific payment flows and error scenarios following provider best practices.

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