# 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.

# getCustomerInfo

Gets the latest CustomerInfo asynchronously.

> **Info:** This method was introduced in version 4.10.0. It provides an async way to get the latest customer information.

## Purpose

Retrieves the latest `CustomerInfo` asynchronously. If customer info is already available, it returns immediately. Otherwise, it waits for the first non-placeholder customer info to be loaded.

## Signature

```swift
public func getCustomerInfo() async -> CustomerInfo

public func getCustomerInfo(completion: @escaping (CustomerInfo) -> Void)
```

## Parameters

No parameters for the async version. The completion handler version takes a completion closure.

## Returns / State

Returns a `CustomerInfo` object containing the latest customer purchase and subscription data.

## Usage

Using async/await:

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

// Use the customer info
print("User has \(customerInfo.subscriptions.count) subscriptions")
print("Active product IDs: \(customerInfo.activeSubscriptionProductIds)")
```

Using completion handler:

```swift
Superwall.shared.getCustomerInfo { customerInfo in
  // Handle customer info
  print("User has \(customerInfo.subscriptions.count) subscriptions")
  
  // Update UI on main thread
  DispatchQueue.main.async {
    self.updatePurchaseHistory(customerInfo)
  }
}
```

In a Task:

```swift
Task {
  let customerInfo = await Superwall.shared.getCustomerInfo()
  
  // Process customer info
  await processCustomerInfo(customerInfo)
}
```
