)

Test Conversion Values:

// Get conversion value without sending to Apple
let value = DatalyrSDK.getConversionValue(
  for: "purchase",
  properties: ["revenue": 99.99]
)
print("Conversion value: \(value ?? 0)")

Available Templates:

"ecommerce": Revenue-based encoding (0-6 brackets)
"gaming": Level progression and IAP
"subscription": Trial, active, churned states

Auto-Events

Revenue Tracking: SDK vs Webhooks

If you use Superwall or RevenueCat, do not use trackPurchase() or trackSubscription() for revenue attribution. These methods fire client-side before payment is confirmed, meaning trials and failed payments will be counted as revenue.Instead, use the Superwall or RevenueCat webhook integration — these send server-side events only when real money changes hands, with accurate revenue, trial status, and refund data.

With Superwall/RevenueCat (recommended for subscription apps):

Use the DATALYR SDK for behavioral events only: track('paywall_view'), track('trial_start'), screen(), identify(), etc.
Use the webhook integration for revenue events: purchases, renewals, cancellations, refunds
Pass attribution to Superwall/RevenueCat using getSuperwallAttributes() or getRevenueCatAttributes() so revenue events get linked back to the original campaign

Without Superwall/RevenueCat:

Use trackPurchase() and trackSubscription() only after confirming a real charge (not a trial start)
These methods are appropriate for one-time purchases or when you handle billing directly

Common Use Cases

E-commerce App

// Product view
await Datalyr.track('product_view', {
  product_id: 'prod_123',
  name: 'Premium Widget',
  price: 99.99
});

// Add to cart
await Datalyr.track('add_to_cart', {
  product_id: 'prod_123',
  quantity: 2
});

// Purchase (with SKAdNetwork on iOS)
// Only use if NOT using Superwall/RevenueCat for revenue
await Datalyr.trackPurchase(199.98, 'USD', 'prod_123');

Subscription App (with Superwall/RevenueCat)

// Use SDK for behavioral events
await Datalyr.track('paywall_view', { paywall_id: 'main' });
await Datalyr.track('trial_start', { plan: 'pro', duration: 14 });

// Pass attribution to Superwall/RevenueCat
const attrs = Datalyr.getSuperwallAttributes(); // or getRevenueCatAttributes()
Superwall.setUserAttributes(attrs);

// Revenue is tracked automatically via webhooks — don't call trackPurchase()

Subscription App (without Superwall/RevenueCat)

// Trial start — no revenue, so just track the event
await Datalyr.track('trial_start', {
  plan: 'pro',
  duration: 14
});

// Only track revenue after confirming a real charge
await Datalyr.trackSubscription(9.99, 'USD', 'monthly');

// Subscription cancel
await Datalyr.track('subscription_cancel', {
  plan: 'monthly',
  reason: 'too_expensive'
});

Gaming App

// Level complete
await Datalyr.trackWithSKAdNetwork('level_complete', {
  level: 5,
  score: 1250,
  time: 180
});

// In-app purchase
await Datalyr.trackPurchase(4.99, 'USD', 'coins_1000');

// Achievement unlocked
await Datalyr.track('achievement', {
  achievement_id: 'first_win',
  points: 100
});

Best Practices

Initialize Early: Initialize SDK in AppDelegate (iOS) or index.js (React Native) before any events. Flush Before Exit: SDK automatically flushes on app background, but manually call flush() for critical events. Handle Offline: SDK queues events offline and sends when connection restored. Test Conversion Values: Use getConversionValue() to test SKAdNetwork encoding before production. Privacy: Enable respectDoNotTrack and collect user consent before tracking.

Migrating from AppsFlyer / Adjust

DATALYR provides similar functionality to AppsFlyer and Adjust with a simpler integration and bundled platform SDKs.

From AppsFlyer

// BEFORE: AppsFlyer
import appsFlyer from 'react-native-appsflyer';
appsFlyer.initSdk({ devKey: 'YOUR_DEV_KEY', appId: 'YOUR_APP_ID' });
appsFlyer.logEvent('af_purchase', { af_revenue: 99.99, af_currency: 'USD' });

// AFTER: DATALYR
import { Datalyr } from '@datalyr/react-native';
await Datalyr.initialize({ apiKey: 'dk_your_api_key' });
await Datalyr.trackPurchase(99.99, 'USD', 'product_id');

From Adjust

// BEFORE: Adjust
import { Adjust, AdjustConfig, AdjustEvent } from 'react-native-adjust';
const config = new AdjustConfig('YOUR_TOKEN', AdjustConfig.EnvironmentProduction);
Adjust.create(config);
const event = new AdjustEvent('abc123');
event.setRevenue(99.99, 'USD');
Adjust.trackEvent(event);

// AFTER: DATALYR
import { Datalyr } from '@datalyr/react-native';
await Datalyr.initialize({ apiKey: 'dk_your_api_key' });
await Datalyr.trackPurchase(99.99, 'USD');

Event Name Mapping

AppsFlyer Event	Adjust Event	DATALYR Method
`af_purchase`	`PURCHASE`	`trackPurchase()`
`af_add_to_cart`	`ADD_TO_CART`	`trackAddToCart()`
`af_initiated_checkout`	`INITIATE_CHECKOUT`	`trackInitiateCheckout()`
`af_complete_registration`	`COMPLETE_REGISTRATION`	`trackCompleteRegistration()`
`af_content_view`	`VIEW_CONTENT`	`trackViewContent()`
`af_search`	`SEARCH`	`trackSearch()`
`af_subscribe`	`SUBSCRIBE`	`trackSubscription()`

Migration Benefits

No Ad SDKs Required: Uses native Apple and Google frameworks for IDFA and GAID
Unified API: Single SDK for all platforms and ad networks
Web-to-App: Automatic attribution matching via email
Flat Pricing: No per-MAU charges

Troubleshooting
