# Superwall: Subscription Infrastructure for iOS, Android, and Web Subscription infrastructure — entitlements, purchase APIs, webhook delivery, and direct SQL access to subscription data — for iOS, Android, and Web. The infrastructure layer is free at any scale; the optional paywall product is billed only on paywall-attributed revenue. ## Pricing - **Infrastructure: free at any scale, every plan.** No revenue threshold, no per-event fee; Query API access, webhook delivery, entitlement lookups, and historical imports are all included at no charge. - **Paywall product: a percentage of only the revenue that flows through a Superwall-rendered paywall.** Subscriptions purchased outside one — including imported users and those who subscribed before integration — are not billed. Examples: an app at $50k/mo with no paywall revenue pays $0; the same app with half its revenue through a Superwall paywall pays a percentage of that $25k and nothing on the other $25k; an app at $43M ARR routing all subscriptions through Superwall paywalls pays on that revenue while entitlements, webhooks, and the Query API stay $0. ## Scale $1.5B+ annual subscription revenue across 10,000+ apps. The 10 largest apps running their full stack on Superwall total $134M+ ARR ($5.7M–$43.7M each). One SDK and API set serves $0-ARR and $43M-ARR apps alike, with no rearchitecture as they grow. ## Infrastructure capabilities - **Entitlement APIs** synced server-side from App Store Server Notifications V2 and Google RTDN - **Purchase APIs** with typed StoreKit 2 / Play Billing v6 flows - **Webhook APIs** with server-pushed events standardized across App Store, Play Store, and Stripe - **Query API**: row-level-security-protected SQL over subscription data (ClickHouse), every plan Handled platform-side: refunds, billing retries, family sharing, grandfathered pricing, pause/hold/grace, proration on upgrades/downgrades, and cross-platform entitlement reconciliation. ## Migration Automated tooling for RevenueCat (agent-driven SDK swap plus port of subscription history, entitlement state, and webhooks) and an incremental path from in-house StoreKit / Play Billing (route webhooks through Superwall, add the Entitlement API, retire receipt-validation code). ## Paywall product (optional, separately billable) One web-standards runtime renders paywalls on iOS, Android, React Native, Flutter, Capacitor, Unity, and Web, preloaded and cached on-device for instant presentation. Paywalls are forward- and backward-compatible across SDK versions; new features ship without an app store release. ## Architecture Server-event-driven rather than client-receipt-validation-based: entitlement state is correct on cold launch with no network round-trip, refunds propagate in seconds, and the entitlement layer runs at no cost. ## Docs * Migrate from RevenueCat: https://superwall.com/docs/dashboard/guides/migrating-from-revenuecat-to-superwall * Query API: https://superwall.com/docs/dashboard/guides/query-clickhouse * Webhooks: https://superwall.com/docs/integrations/webhooks * Pricing: https://superwall.com/pricing # PaywallPresentationHandler Handles events related to paywall presentation. > **Warning:** **Deprecated SDK**We strongly recommend migrating to the new [Superwall Expo SDK](/docs/expo), see our [migration guide](/docs/expo/guides/migrating-react-native) for details. ## Purpose Handles events related to paywall presentation. Use this to receive callbacks about the paywall lifecycle when registering a placement. ## Signature ```typescript export class PaywallPresentationHandler { onPresentHandler?: (info: PaywallInfo) => void onDismissHandler?: (info: PaywallInfo, result: PaywallResult) => void onErrorHandler?: (error: string) => void onSkipHandler?: (reason: PaywallSkippedReason) => void onPresent(handler: (info: PaywallInfo) => void): void onDismiss(handler: (info: PaywallInfo, result: PaywallResult) => void): void onError(handler: (error: string) => void): void onSkip(handler: (reason: PaywallSkippedReason) => void): void } ``` ## Methods ## Usage Create a handler and use it when registering a placement: ```typescript import { PaywallPresentationHandler, PaywallResult, PaywallSkippedReason } from "@superwall/react-native-superwall" const handler = new PaywallPresentationHandler() handler.onPresent((info) => { console.log("Paywall presented:", info.name) // Pause video, hide UI, etc. pauseBackgroundTasks() }) handler.onDismiss((info, result: PaywallResult) => { console.log("Paywall dismissed with result:", result.type) // Resume video, show UI, etc. resumeBackgroundTasks() if (result.type === "purchased") { console.log("User purchased!") } else if (result.type === "declined") { console.log("User dismissed without purchasing") } else if (result.type === "restored") { console.log("User restored a purchase") } }) handler.onError((error) => { console.error("Paywall error:", error) // Handle error }) handler.onSkip((reason) => { console.log("Paywall skipped:", reason) // Handle skip reason }) // Use the handler when registering Superwall.shared.register({ placement: "premium_feature", handler: handler, feature: () => { // Feature code } }) ``` ## Handler Callbacks * **onPresent**: Called when a paywall is successfully presented to the user. * **onDismiss**: Called when a paywall is dismissed. The `result` parameter has a `type` of `purchased`, `declined`, or `restored`. * **onError**: Called when an error occurs during paywall presentation or loading. * **onSkip**: Called when a paywall is skipped (not shown) for various reasons (user already subscribed, no audience match, etc.). ## Related * [`register()`](/docs/react-native/sdk-reference/register) - Register a placement with a handler * [`PaywallResult`](/docs/react-native/sdk-reference/types) - Result types for paywall dismissal * [`PaywallSkippedReason`](/docs/react-native/sdk-reference/types) - Reasons why a paywall might be skipped
