  title: RevenueCat REST Apps Customers API
  description: Representative OpenAPI description of RevenueCat's public REST surface. It covers the v1 REST API (https://api.revenuecat.com/v1) for subscribers, receipts/purchases, entitlements, offerings, and subscriber attributes, and the v2 REST API (https://api.revenuecat.com/v2) for projects, apps, customers, products, entitlements, offerings, and packages. Both APIs use HTTP Bearer authentication with a RevenueCat API key (v1 public or secret keys; v2 API keys). RevenueCat also delivers subscription lifecycle events via outbound webhooks (documented separately).
