# 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.

# getEntitlements()

Gets all entitlements available to the user, organized by status.

## Purpose

Retrieves all entitlements available to the user, organized into active, inactive, all, and web entitlements. Also provides a method to filter entitlements by product IDs.

## Signature

```dart
Future<Entitlements> getEntitlements()
```

## Returns / State

Returns a `Future<Entitlements>` containing:

* `active` - Set of active entitlements
* `inactive` - Set of inactive entitlements
* `all` - Set of all entitlements (active and inactive)
* `web` - Set of entitlements from web checkout
* `byProductIds(productIds)` - Method to filter entitlements by product IDs

## Usage

Getting all entitlements:

```dart
final entitlements = await Superwall.shared.getEntitlements();

print('Active: ${entitlements.active.length}');
print('Inactive: ${entitlements.inactive.length}');
print('Total: ${entitlements.all.length}');
print('Web: ${entitlements.web.length}');
```

Checking for specific entitlements:

```dart
final entitlements = await Superwall.shared.getEntitlements();

final hasPremium = entitlements.active.any(
  (entitlement) => entitlement.id == 'premium',
);

if (hasPremium) {
  print('User has premium access');
}
```

Filtering entitlements by product IDs:

```dart
final entitlements = await Superwall.shared.getEntitlements();

// Get entitlements that contain any of these product IDs
final filtered = await entitlements.byProductIds({
  'premium_monthly',
  'premium_yearly',
});

print('Found ${filtered.length} entitlements for those products');
```

Checking web checkout entitlements:

```dart
final entitlements = await Superwall.shared.getEntitlements();

if (entitlements.web.isNotEmpty) {
  print('User has ${entitlements.web.length} web checkout entitlements');
  for (final entitlement in entitlements.web) {
    print('Web entitlement: ${entitlement.id}');
  }
}
```
