# 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.

# customerInfo

Contains the latest information about all of the customer's purchase and subscription data.

> **Info:** `CustomerInfo` was introduced in version 4.10.0. It provides comprehensive information about the customer's purchase history, subscriptions, and entitlements.

> **Note:** `CustomerInfo` is a published property, so you can subscribe to it using Combine or SwiftUI. You can also use the delegate method [`customerInfoDidChange(from:to:)`](/docs/ios/sdk-reference/SuperwallDelegate#customerinfodidchange) or the `AsyncStream` [`customerInfoStream`](/docs/ios/sdk-reference/Superwall#customerinfostream).

## Purpose

Provides access to the customer's complete purchase and subscription history, including all transactions and entitlements. This is useful for displaying purchase history, understanding subscription status, and implementing features that depend on transaction data.

## Signature

```swift
@Published
public var customerInfo: CustomerInfo { get }
```

## Properties

<TypeTable
  type="{
  subscriptions: {
    type: &#x22;[SubscriptionTransaction]&#x22;,
    description: &#x22;All subscription transactions, ordered by purchase date (ascending).&#x22;,
    required: true,
  },
  nonSubscriptions: {
    type: &#x22;[NonSubscriptionTransaction]&#x22;,
    description: &#x22;All non-subscription transactions (consumables and non-consumables), ordered by purchase date (ascending).&#x22;,
    required: true,
  },
  entitlements: {
    type: &#x22;[Entitlement]&#x22;,
    description: &#x22;All entitlements available to the user.&#x22;,
    required: true,
  },
  activeSubscriptionProductIds: {
    type: &#x22;Set<String>&#x22;,
    description: &#x22;Product identifiers for active subscriptions.&#x22;,
    required: true,
  },
  userId: {
    type: &#x22;String&#x22;,
    description: &#x22;The ID of the user. Equivalent to Superwall.userId.&#x22;,
    required: true,
  },
}"
/>

## Returns / State

Returns a `CustomerInfo` object containing the latest customer purchase and subscription data. This object is immutable and does not update automatically—you must access the property again to get the latest data.

## Usage

Access customer info:

```swift
let customerInfo = Superwall.shared.customerInfo

// Get all subscriptions
let subscriptions = customerInfo.subscriptions

// Get all non-subscription purchases
let nonSubscriptions = customerInfo.nonSubscriptions

// Get all entitlements
let entitlements = customerInfo.entitlements

// Get active subscription product IDs
let activeProductIds = customerInfo.activeSubscriptionProductIds
```

Observe changes with Combine:

```swift
import Combine

class ViewController: UIViewController {
  private var cancellables = Set<AnyCancellable>()
  
  override func viewDidLoad() {
    super.viewDidLoad()
    
    Superwall.shared.$customerInfo
      .sink { [weak self] customerInfo in
        self?.updatePurchaseHistory(customerInfo)
      }
      .store(in: &cancellables)
  }
  
  func updatePurchaseHistory(_ customerInfo: CustomerInfo) {
    // Update UI with purchase history
    print("User has \(customerInfo.subscriptions.count) subscriptions")
    print("User has \(customerInfo.nonSubscriptions.count) non-subscription purchases")
  }
}
```

Use with AsyncStream (iOS 15+):

```swift
Task {
  for await customerInfo in Superwall.shared.customerInfoStream {
    // Handle customer info updates
    print("Customer info updated: \(customerInfo.subscriptions.count) subscriptions")
  }
}
```

Get customer info asynchronously:

```swift
// Using async/await
let customerInfo = await Superwall.shared.getCustomerInfo()

// Using completion handler
Superwall.shared.getCustomerInfo { customerInfo in
  // Handle customer info
}
```

Display purchase history:

```swift
func displayPurchaseHistory() {
  let customerInfo = Superwall.shared.customerInfo
  
  // Display subscriptions
  for subscription in customerInfo.subscriptions {
    print("Product: \(subscription.productId)")
    print("Purchase Date: \(subscription.purchaseDate)")
    print("Active: \(subscription.isActive)")
    if let expirationDate = subscription.expirationDate {
      print("Expires: \(expirationDate)")
    }
  }
  
  // Display non-subscription purchases
  for purchase in customerInfo.nonSubscriptions {
    print("Product: \(purchase.productId)")
    print("Purchase Date: \(purchase.purchaseDate)")
    print("Consumable: \(purchase.isConsumable)")
  }
}
```

Check active subscriptions:

```swift
func hasActiveSubscription() -> Bool {
  let customerInfo = Superwall.shared.customerInfo
  return !customerInfo.activeSubscriptionProductIds.isEmpty
}

func getActiveSubscriptionProductIds() -> Set<String> {
  return Superwall.shared.customerInfo.activeSubscriptionProductIds
}
```
