Use Case: Onboarding to Premium

The most common integration pattern for subscription apps. This guide walks through the full flow: app launch, onboarding with data capture, user identification, paywall presentation, purchase handling, and premium unlock.

What You’ll Build

App launch → Initialize SDK → Present onboarding → Capture quiz answers →
Identify user with traits → Present paywall → Handle purchase → Unlock premium

Step 1: Initialize the SDK

Configure AppDNA as early as possible in your app’s lifecycle.

iOS
Android
Flutter
React Native

import AppDNASDK

// AppDelegate.swift
func application(_ app: UIApplication, didFinishLaunchingWithOptions _: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
    AppDNA.configure(
        apiKey: "adn_live_xxx",
        environment: .production,
        options: AppDNAOptions(billingProvider: .storeKit2)
    )
    return true
}

import ai.appdna.sdk.AppDNA
import ai.appdna.sdk.AppDNAOptions
import ai.appdna.sdk.Environment

// Application.onCreate()
// Android always uses Google Play Billing — no billingProvider option needed.
AppDNA.configure(
    context = this,
    apiKey = "adn_live_xxx",
    environment = Environment.PRODUCTION,
    options = AppDNAOptions()
)

import 'package:appdna_sdk/appdna_sdk.dart';

await AppDNA.configure(
  apiKey: "adn_live_xxx",
  env: AppDNAEnvironment.production,
  options: AppDNAOptions(billingProvider: AppDNABillingProvider.storeKit2),
);

import { AppDNA } from "@appdna-ai/react-native-sdk";

await AppDNA.configure("adn_live_xxx", "production", {
  billingProvider: "storeKit2",
});

Step 2: Present Onboarding

The onboarding flow is designed in the Console — the SDK renders it natively. Present it on first launch:

iOS
Android
Flutter
React Native

let presented = AppDNA.presentOnboarding(
    flowId: nil,  // Uses the active flow from Console
    from: viewController,
    delegate: self
)

if !presented {
    // No active flow or config not loaded -- skip to home
    navigateToHome()
}

val presented = AppDNA.presentOnboarding(
    activity = this,
    flowId = null,
    listener = this
)

if (!presented) {
    navigateToHome()
}

// Flutter's present takes a required flowId and returns void.
await AppDNA.onboarding.present("welcome");

const presented = await AppDNA.onboarding.present("welcome");

if (!presented) {
  navigateToHome();
}

On iOS and Android, flowId is optional — pass null to present whatever flow is currently active in the Console, letting you swap onboarding flows remotely without an app update. On Flutter and React Native, present takes a specific flow ID.

Step 3: Capture Quiz Answers via Callbacks

The onboarding delegate gives you every answer the user provides. Use these for personalization and segmentation.

iOS
Android
Flutter
React Native

class AppCoordinator: AppDNAOnboardingDelegate {
    func onOnboardingStepChanged(flowId: String, stepId: String, stepIndex: Int, totalSteps: Int) {
        // Update progress UI if you have one
    }

    func onOnboardingCompleted(flowId: String, responses: [String: Any]) {
        // responses contains all quiz answers:
        // ["fitness_goal": "lose_weight", "experience_level": "beginner", "age_group": "25-34"]

        handleOnboardingComplete(responses: responses)
    }

    func onOnboardingDismissed(flowId: String, atStep: Int) {
        // User skipped onboarding -- still proceed
        navigateToPaywall()
    }
}

override fun onOnboardingCompleted(flowId: String, responses: Map<String, Any>) {
    // responses contains all quiz answers
    handleOnboardingComplete(responses)
}

override fun onOnboardingDismissed(flowId: String, atStep: Int) {
    navigateToPaywall()
}

@override
void onOnboardingCompleted(String flowId, Map<String, dynamic> responses) {
  handleOnboardingComplete(responses);
}

@override
void onOnboardingDismissed(String flowId, int atStep) {
  navigateToPaywall();
}

// Register the onboarding delegate once, at app startup.
AppDNA.onboarding.setDelegate({
  onOnboardingCompleted: (flowId, responses) => {
    handleOnboardingComplete(responses);
  },
  onOnboardingDismissed: (flowId, atStep) => {
    navigateToPaywall();
  },
  // ...implement the other AppDNAOnboardingDelegate methods
});

Conditional Branching

Onboarding flows support conditional branching — the next step changes based on the user’s answer. This is configured entirely in the Console:

Step 1: "What's your fitness goal?"
  → "Lose weight"  → Step 2a: Weight loss program details
  → "Build muscle" → Step 2b: Muscle building program details
  → "Stay active"  → Step 2c: General wellness details

To configure branching:

Open your flow in the Console (Onboarding > Flows)
On a question step, click Add branching rule
Map each answer option to a target step

The SDK handles the routing automatically — no code needed.

Step 4: Identify the User with Traits

After onboarding (or after login), link the user’s identity and pass the quiz answers as traits. These traits power experiment targeting, push segmentation, and analytics.

iOS
Android
Flutter
React Native

func handleOnboardingComplete(responses: [String: Any]) {
    // Pass onboarding answers as user traits
    AppDNA.identify(
        userId: authManager.currentUserId,
        traits: responses
    )

    navigateToPaywall()
}

fun handleOnboardingComplete(responses: Map<String, Any>) {
    AppDNA.identify(
        userId = authManager.currentUserId,
        traits = responses
    )
    navigateToPaywall()
}

void handleOnboardingComplete(Map<String, dynamic> responses) {
  AppDNA.identify(authManager.currentUserId, traits: responses);
  navigateToPaywall();
}

function handleOnboardingComplete(responses: Record<string, any>) {
  AppDNA.identify(authManager.currentUserId, responses);
  navigateToPaywall();
}

Depending on your app’s flow, user login can happen at different points: Login during onboarding — if your onboarding includes a signup/login step, call identify() in the step callback:

iOS
Android
Flutter
React Native

func onOnboardingStepChanged(flowId: String, stepId: String, stepIndex: Int, totalSteps: Int) {
    if stepId == "login_step" {
        // User completed login/signup step
        // Your auth flow runs here, then:
        AppDNA.identify(userId: authManager.currentUserId, traits: ["signup_method": "email"])
    }
}

override fun onOnboardingStepChanged(flowId: String, stepId: String, stepIndex: Int, totalSteps: Int) {
    if (stepId == "login_step") {
        AppDNA.identify(userId = authManager.currentUserId, traits = mapOf("signup_method" to "email"))
    }
}

@override
void onOnboardingStepChanged(String flowId, String stepId, int stepIndex, int totalSteps) {
  if (stepId == "login_step") {
    AppDNA.identify(authManager.currentUserId, traits: {"signup_method": "email"});
  }
}

AppDNA.onboarding.setDelegate({
  onOnboardingStepChanged: (flowId, stepId, stepIndex, totalSteps) => {
    if (stepId === "login_step") {
      AppDNA.identify(authManager.currentUserId, { signup_method: "email" });
    }
  },
  // ...implement the other AppDNAOnboardingDelegate methods
});

Login after onboarding — call identify() in your normal auth callback:

iOS
Android
Flutter
React Native

// After OAuth or email/password login completes
func authDidComplete(user: User) {
    AppDNA.identify(
        userId: user.id,
        traits: [
            "provider": user.authProvider,  // "google", "apple", "email"
            "name": user.displayName
        ]
    )
}

fun onAuthComplete(user: User) {
    AppDNA.identify(
        userId = user.id,
        traits = mapOf("provider" to user.authProvider, "name" to user.displayName)
    )
}

void onAuthComplete(User user) {
  AppDNA.identify(user.id, traits: {
    "provider": user.authProvider,
    "name": user.displayName,
  });
}

function onAuthComplete(user: User) {
  AppDNA.identify(user.id, {
    provider: user.authProvider,
    name: user.displayName,
  });
}

Before identify() is called, the SDK tracks events against an anonymous ID. Once you call identify(), all past anonymous events are automatically linked to the user.

Step 5: Present the Paywall

Show the paywall immediately after onboarding. The paywall is designed in the Console — the SDK renders it with built-in purchase handling.

iOS
Android
Flutter
React Native

func navigateToPaywall() {
    AppDNA.presentPaywall(
        id: "post_onboarding",
        from: viewController,
        context: PaywallContext(placement: "onboarding_complete"),
        delegate: self
    )
}

fun navigateToPaywall() {
    AppDNA.presentPaywall(
        activity = this,
        id = "post_onboarding",
        context = PaywallContext(placement = "onboarding_complete"),
        listener = this
    )
}

void navigateToPaywall() {
  AppDNA.paywall.present(
    "post_onboarding",
    context: PaywallContext(placement: "onboarding_complete"),
  );
}

function navigateToPaywall() {
  AppDNA.paywall.present("post_onboarding", {
    placement: "onboarding_complete",
  });
}

Step 6: Handle Purchase Callbacks

React to purchase results via the paywall delegate:

iOS
Android
Flutter
React Native

// Purchase succeeded -- unlock premium
func onPaywallPurchaseCompleted(paywallId: String, productId: String, transaction: TransactionInfo) {
    unlockPremium()
    navigateToHome()
}

// Purchase failed -- paywall stays visible for retry
func onPaywallPurchaseFailed(paywallId: String, error: Error) {
    // Error is shown in the paywall UI automatically
}

// User dismissed without purchasing -- freemium path
func onPaywallDismissed(paywallId: String) {
    navigateToHome()
}

override fun onPaywallPurchaseCompleted(paywallId: String, productId: String, transaction: TransactionInfo) {
    unlockPremium()
    navigateToHome()
}

override fun onPaywallPurchaseFailed(paywallId: String, error: Throwable) {
    // Error shown in paywall UI
}

override fun onPaywallDismissed(paywallId: String) {
    navigateToHome()
}

@override
void onPaywallPurchaseCompleted(String paywallId, String productId, Map<String, dynamic> transaction) {
  unlockPremium();
  navigateToHome();
}

@override
void onPaywallDismissed(String paywallId) {
  navigateToHome();
}

// Register the paywall delegate once, at app startup.
AppDNA.paywall.setDelegate({
  onPaywallPurchaseCompleted: (paywallId, productId, transaction) => {
    unlockPremium();
    navigateToHome();
  },
  onPaywallDismissed: (paywallId) => {
    navigateToHome();
  },
  // ...implement the other AppDNAPaywallDelegate methods
});

    private let viewController: UIViewController

    init(viewController: UIViewController) {
        self.viewController = viewController
    }

    // MARK: - Entry Point

    func start() {
        let presented = AppDNA.presentOnboarding(
            flowId: nil,
            from: viewController,
            delegate: self
        )
        if !presented { navigateToPaywall() }
    }

        // Pass quiz answers as traits for segmentation
        if let userId = AuthManager.shared.currentUserId {
            AppDNA.identify(userId: userId, traits: responses)
        }
        navigateToPaywall()

What Happens Behind the Scenes

You don’t need to manage any of this — the SDK handles it automatically:

Onboarding config is fetched from the Console and cached locally (works offline)
Every step event is tracked automatically (onboarding_flow_started, step_viewed, step_completed, etc.)
User traits sync to AppDNA for segmentation and experiment targeting
Paywall config and product prices are resolved from cache
Purchases are verified server-side automatically
All events are batched and sent reliably (persisted to disk, retried on failure)

See Auto-Tracked Events for the full list of events tracked during this flow.
