# 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.

# configure()

A static function that configures a shared instance of Superwall for use throughout your app.

> **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.

> **Note:** This is a static method called on the `Superwall` class itself, not on the shared instance.

## Purpose

Configures the shared instance of Superwall with your API key and optional configurations, making it ready for use throughout your app.

## Signature

```typescript
static async configure({
  apiKey,
  options,
  purchaseController,
  completion,
}: {
  apiKey: string
  options?: SuperwallOptions
  purchaseController?: PurchaseController
  completion?: () => void
}): Promise<Superwall>
```

## Parameters

<TypeTable
  type="{
  apiKey: {
    type: &#x22;string&#x22;,
    description: &#x22;Your Public API Key from the Superwall dashboard settings.&#x22;,
    required: true,
  },
  options: {
    type: &#x22;SuperwallOptions?&#x22;,
    typeDescriptionLink: &#x22;/react-native/sdk-reference/SuperwallOptions&#x22;,
    description: &#x22;Optional configuration object for customizing paywall appearance and behavior.&#x22;,
    default: &#x22;undefined&#x22;,
  },
  purchaseController: {
    type: &#x22;PurchaseController?&#x22;,
    description: &#x22;Optional object for handling all subscription-related logic yourself. If omitted, Superwall handles subscription logic.&#x22;,
    default: &#x22;undefined&#x22;,
  },
  completion: {
    type: &#x22;(() => void)?&#x22;,
    description: &#x22;Optional completion handler called when Superwall finishes configuring.&#x22;,
    default: &#x22;undefined&#x22;,
  },
}"
/>

## Returns / State

Returns a Promise that resolves to the configured `Superwall` instance. The instance is also accessible via [`Superwall.shared`](/docs/react-native/sdk-reference/Superwall).

## Usage

Basic configuration:

```typescript
import Superwall from "@superwall/react-native-superwall"

await Superwall.configure({
  apiKey: "pk_your_api_key"
})
```

With custom options:

```typescript
import Superwall, { SuperwallOptions } from "@superwall/react-native-superwall"

const options = new SuperwallOptions({
  paywalls: {
    shouldShowPurchaseFailureAlert: false
  }
})

await Superwall.configure({
  apiKey: "pk_your_api_key",
  options: options,
  completion: () => {
    console.log("Superwall configured successfully")
  }
})
```

With custom purchase controller:

```typescript
import Superwall, { PurchaseController } from "@superwall/react-native-superwall"

class MyPurchaseController extends PurchaseController {
  async purchaseFromAppStore(productId: string): Promise<PurchaseResult> {
    // Your purchase logic
  }
  
  async purchaseFromGooglePlay(productId: string, basePlanId?: string, offerId?: string): Promise<PurchaseResult> {
    // Your purchase logic
  }
  
  async restorePurchases(): Promise<RestorationResult> {
    // Your restore logic
  }
}

await Superwall.configure({
  apiKey: "pk_your_api_key",
  purchaseController: new MyPurchaseController()
})
```
