The API covers products, prices, subscriptions, customers, transactions, discounts, and payment methods. Agents can create and manage subscription plans, handle plan upgrades and downgrades with proration, record usage for usage-based billing, and generate one-off charges. The webhook system provides real-time notification for payment, subscription, and refund lifecycle events.
Paddle Billing is Paddle's next-generation billing API, distinct from Paddle Classic, with a redesigned REST API for subscription management, usage-based billing, and global tax compliance. As a merchant of record, Paddle handles VAT/GST collection and remittance globally — removing the team's obligation to register for tax in each jurisdiction. The new API design is significantly cleaner than Paddle Classic and suitable for direct backend integration without the Classic SDK dependency.
Authentication uses API keys for the REST API. Paddle Billing separates sandbox and production API keys clearly, enabling safe development and testing against synthetic billing data. Webhook signature verification ensures agents process only genuine Paddle webhook events.
Reliability is production-grade for a global payment infrastructure platform. Paddle maintains the availability required for checkout and subscription management in global markets. Billing operations should implement idempotency where Paddle supports it to prevent duplicate charges during network error retry scenarios.
Documentation is comprehensive and reflects the new API design's quality improvement over Paddle Classic. The subscription lifecycle documentation covers the proration and plan change behavior clearly, which is important for agents implementing upgrade/downgrade flows. Teams migrating from Paddle Classic should review the new API's structural differences before integration.
