RevenueCat
RevenueCat provides in-app subscription and purchase infrastructure for mobile and web apps. It abstracts App Store, Google Play, Amazon, Stripe, Roku, and Paddle billing behind cross-platform SDKs and a REST API, handling receipt validation, entitlements, subscriber state, offerings and paywalls, experiments, and subscription analytics. A v1 REST API manages live subscribers and purchases; a v2 REST API manages the project catalog (projects, apps, products, entitlements, offerings, packages); webhooks stream subscription lifecycle events.
RevenueCat publishes 11 APIs on the APIs.io network, including Apps API, Customers API, Entitlements (v1) API, and 8 more. Tagged areas include Subscriptions, In-App Purchases, Billing, Mobile, and Entitlements.
RevenueCat’s developer surface includes authentication, documentation, engineering blog, and 8 more developer resources.
