# 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.

# NonSubscriptionTransaction

Represents a non-subscription transaction (consumables and non-consumables).

> **Info:** Introduced in 4.10.0. The `store` property was added in 4.11.0.

## Purpose

Provides details about one-time purchases in [`CustomerInfo`](/docs/ios/sdk-reference/customerInfo), including which store fulfilled the purchase.

## Properties

<TypeTable
  type="{
  transactionId: {
    type: &#x22;String&#x22;,
    description: &#x22;Unique identifier for the transaction.&#x22;,
    required: true,
  },
  productId: {
    type: &#x22;String&#x22;,
    description: &#x22;Product identifier for the purchase.&#x22;,
    required: true,
  },
  purchaseDate: {
    type: &#x22;Date&#x22;,
    description: &#x22;When the charge occurred.&#x22;,
    required: true,
  },
  isConsumable: {
    type: &#x22;Bool&#x22;,
    description: &#x22;`true` for consumables, `false` for non-consumables.&#x22;,
    required: true,
  },
  isRevoked: {
    type: &#x22;Bool&#x22;,
    description: &#x22;`true` if the transaction has been revoked.&#x22;,
    required: true,
  },
  store: {
    type: &#x22;ProductStore&#x22;,
    description: &#x22;Store that fulfilled the purchase (4.11.0+).&#x22;,
    required: true,
  },
}"
/>

### Store values

`appStore`, `stripe`, `paddle`, `playStore`, `superwall`, `custom`, `other`.

## Usage

Inspect non-subscription purchases:

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

for purchase in customerInfo.nonSubscriptions {
  print("Product: \(purchase.productId)")
  print("Store: \(purchase.store)")
  print("Consumable: \(purchase.isConsumable)")
  print("Revoked: \(purchase.isRevoked)")
}
```
