# 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.

# handleDeepLink()

A function that handles deep links and triggers paywalls based on configured campaigns.

> **Tip:** Configure deep link campaigns on the Superwall dashboard by adding the `deepLink` event to a campaign trigger.

> **Info:** Deep link events are also tracked via [`SuperwallEvent.deepLink`](/docs/ios/sdk-reference/SuperwallEvent) and sent to your [`SuperwallDelegate`](/docs/ios/sdk-reference/SuperwallDelegate).

## Purpose

Processes a deep link URL and triggers any associated paywall campaigns configured on the Superwall dashboard. Returns whether Superwall will handle the URL so you can fall back to your own routing.

## Signature

```swift
@discardableResult
public static func handleDeepLink(_ url: URL) -> Bool
```

## Parameters

<TypeTable
  type="{
  url: {
    type: &#x22;URL&#x22;,
    description: &#x22;The deep link URL to process for paywall triggers.&#x22;,
    required: true,
  },
}"
/>

## Returns / State

Returns `true` when Superwall will handle the URL. If called before `Superwall.configure(...)` completes, it only returns `true` for known Superwall URL formats or when cached config contains a `deepLink_open` trigger. Use the return value to continue your own deep-link handling when it is `false`.

## Usage

In your SceneDelegate or AppDelegate:

```swift
func scene(_ scene: UIScene, openURLContexts URLContexts: Set<UIOpenURLContext>) {
  guard let url = URLContexts.first?.url else { return }
  
  // Handle the deep link with Superwall
  let handled = Superwall.handleDeepLink(url)
  
  // Continue with your app's deep link handling if Superwall won't
  if !handled {
    handleAppDeepLink(url)
  }
}
```

iOS 13+ SceneDelegate:

```swift
func scene(_ scene: UIScene, willConnectTo session: UISceneSession, options connectionOptions: UIScene.ConnectionOptions) {
  // Handle deep link on app launch
  if let url = connectionOptions.urlContexts.first?.url {
    let handled = Superwall.handleDeepLink(url)
    if !handled {
      handleAppDeepLink(url)
    }
  }
}
```

Legacy AppDelegate:

```swift
func application(_ app: UIApplication, open url: URL, options: [UIApplication.OpenURLOptionsKey : Any] = [:]) -> Bool {
  // Handle the deep link with Superwall
  let handled = Superwall.handleDeepLink(url)
  
  // Continue with your app's deep link handling
  if handled {
    return true
  }
  return handleAppDeepLink(url)
}
```
