RevenueCat Skill

Expert assistance for implementing in-app subscriptions and purchases using RevenueCat across iOS, Android, Flutter, React Native, and web platforms.

When to Use This Skill

This skill should be triggered when:

• SDK Setup : Initializing RevenueCat SDK in iOS, Android, Flutter, or React Native apps
• Subscription Implementation : Adding subscription or in-app purchase functionality
• Entitlement Checks : Verifying user access to premium features or content
• Purchase Flow : Implementing buy buttons, handling transactions, or processing purchases
• Restore Purchases : Adding restore functionality for users switching devices
• Offerings/Products : Fetching and displaying subscription options or product catalogs
• Paywall Design : Building or configuring paywalls and purchase screens
• Customer Info : Retrieving subscription status or customer data
• Debugging Purchases : Troubleshooting subscription issues or transaction failures
• REST API Integration : Server-side subscription validation or webhook handling

Quick Reference

SDK Configuration

Swift (iOS)

import RevenueCat

Purchases.logLevel = .debug
Purchases.configure(withAPIKey: "your_public_api_key", appUserID: "user_123")

Kotlin (Android)

Purchases.logLevel = LogLevel.DEBUG
Purchases.configure(PurchasesConfiguration.Builder(this, "your_public_api_key").build())

Flutter

await Purchases.setLogLevel(LogLevel.debug);
PurchasesConfiguration configuration = PurchasesConfiguration("your_public_api_key");
await Purchases.configure(configuration);

React Native

Purchases.setLogLevel(Purchases.LOG_LEVEL.DEBUG);
Purchases.configure({ apiKey: "your_public_api_key" });

Checking Entitlements

Swift

let customerInfo = try await Purchases.shared.customerInfo()
if customerInfo.entitlements["pro"]?.isActive == true {
    // User has premium access
}

Kotlin

Purchases.sharedInstance.getCustomerInfoWith(
    onSuccess = { customerInfo ->
        if (customerInfo.entitlements["pro"]?.isActive == true) {
            // User has premium access
        }
    }
)

React Native

const customerInfo = await Purchases.getCustomerInfo();
if (customerInfo.entitlements.active["pro"] !== undefined) {
    // User has premium access
}

Fetching Offerings

Swift

Purchases.shared.getOfferings { (offerings, error) in
    if let packages = offerings?.current?.availablePackages {
        self.display(packages)
    }
}

Kotlin

Purchases.sharedInstance.getOfferingsWith({ error -> }) { offerings ->
    offerings.current?.availablePackages?.let { packages ->
        // Display packages
    }
}

Making a Purchase

Swift

Purchases.shared.purchase(package: package) { (transaction, customerInfo, error, userCancelled) in
    if customerInfo.entitlements["pro"]?.isActive == true {
        // Unlock premium content
    }
}

Kotlin

Purchases.sharedInstance.purchase(
    packageToPurchase = aPackage,
    onError = { error, userCancelled -> },
    onSuccess = { storeTransaction, customerInfo ->
        if (customerInfo.entitlements["pro"]?.isActive == true) {
            // Unlock premium content
        }
    }
)

Restoring Purchases

Swift

Purchases.shared.restorePurchases { customerInfo, error in
    // Check customerInfo to see if entitlement is now active
}

Kotlin

Purchases.sharedInstance.restorePurchases(
    onError = { error -> },
    onSuccess = { customerInfo ->
        // Check customerInfo to see if entitlement is now active
    }
)

REST API - Get Customer Info

curl --request GET \
  --url https://api.revenuecat.com/v1/subscribers/app_user_id \
  --header 'Authorization: Bearer PUBLIC_API_KEY'

Key Concepts

Entitlements

A level of access, features, or content that a user is "entitled" to. Most apps use a single entitlement (e.g., "pro"). Created in the RevenueCat dashboard and linked to products. When a product is purchased, its associated entitlements become active.

Offerings

The set of products available to a user. Configured remotely in the dashboard, allowing you to change available products without app updates. Access via offerings.current for the default offering.

Packages

Containers for products within an offering. Include convenience accessors like .monthly, .annual, .lifetime. Each package contains a storeProduct with pricing details.

CustomerInfo

The central object containing all subscription and purchase data for a user. Retrieved via getCustomerInfo() or returned after purchases. Contains the entitlements dictionary for access checks.

App User ID

Unique identifier for each user. Can be provided during configuration or auto-generated as an anonymous ID. Used to sync purchases across devices.

Working with This Skill

For Beginners

1. Start by configuring the SDK in your app's initialization code
2. Create entitlements and offerings in the RevenueCat dashboard
3. Implement a simple entitlement check before showing premium content
4. Add a purchase button using purchase(package:)
5. Include a "Restore Purchases" button for App Store compliance

For Intermediate Users

• Implement dynamic paywalls by fetching offerings and displaying packages
• Handle multiple entitlements for tiered access levels
• Set up customer info listeners for real-time subscription updates
• Use the REST API for server-side validation

For Advanced Users

• Configure webhooks for server-side event handling
• Implement A/B testing with different offerings
• Set up integrations with analytics and attribution platforms
• Handle edge cases like grace periods and billing retry

Common Patterns

Paywall Display Logic

// Show paywall only if user doesn't have active subscription
if customerInfo.entitlements["pro"]?.isActive != true {
    showPaywall()
}

Conditional Offerings

if user.isPaidDownload {
    packages = offerings?.offering(identifier: "paid_download_offer")?.availablePackages
} else {
    packages = offerings?.current?.availablePackages
}

Important Notes

• Always initialize the SDK early in your app's lifecycle
• Use debug logging during development (Purchases.logLevel = .debug)
• The SDK automatically finishes/acknowledges transactions
• Only call restorePurchases from user interaction (like a button tap)
• Use public API keys from Project Settings; never expose secret keys
• Test Store allows development testing without real charges
