This SDK focuses on web attribution only. + +2. **Cross-Platform Attribution** - Both providers offer solutions to track user journeys across web and mobile apps. This SDK is web-only. + +3. **Smart Banners** - AppsFlyer's SDK includes Smart Banners for web-to-app conversion. Not included in this SDK. + +4. **Fraud Detection** - AppsFlyer includes built-in fraud detection mechanisms (SDK spoofing, click injection, etc.). This SDK relies on your backend for fraud prevention. + +5. **GDPR Compliance Tools** - Adjust provides built-in GDPR compliance features like "Forget Me" and marketing opt-out. You'll need to implement these on your backend. + +6. **Real-time Attribution Callbacks** - Both providers offer real-time attribution callbacks. This SDK queues events and sends them via your API endpoint. + +7. **Server-side Event Forwarding** - Both providers offer server-side event forwarding APIs. This SDK focuses on client-side tracking. + +**Why these features are excluded:** +- **Minimal bundle size** - Keeping the SDK lightweight and dependency-free +- **Web-only focus** - Mobile SDKs will be separate packages +- **Backend flexibility** - Advanced features like fraud detection and GDPR compliance are better handled server-side +- **Simplicity** - Focus on core attribution tracking that works everywhere + +## Migration Guides + +### Complete Migration Guide: AppsFlyer Web SDK → @imtbl/attribution + +This guide will help you migrate from AppsFlyer Web SDK to `@imtbl/attribution` with minimal code changes. + +#### Step 1: Installation + +**Before:** +```bash +npm install appsflyer-web-sdk +``` + +**After:** +```bash +npm install @imtbl/attribution +``` + +#### Step 2: Initialization + +**Before (AppsFlyer):** +```typescript +import { appsFlyer } from 'appsflyer-web-sdk'; + +appsFlyer.init('your-app-id', { + devKey: 'your-dev-key', + isDebug: false, + useCachedDeepLink: true, +}); +``` + +**After (@imtbl/attribution):** +```typescript +import { Attribution } from '@imtbl/attribution'; + +const attribution = new Attribution({ + apiEndpoint: 'https://api.example.com/events', // Required - your backend endpoint + apiKey: 'your-api-key', // Optional: for authentication + trackPageViews: true, // Automatically track page views + parseOnInit: true, // Parse attribution from URL on init +}); +``` + +#### Step 3: Get Anonymous ID + +**Before (AppsFlyer):** +```typescript +const uid = appsFlyer.getAppsFlyerUID(); +console.log(uid); // e.g., "12345678-1234-1234-1234-123456789012" +``` + +**After (@imtbl/attribution):** +```typescript +const uid = attribution.getAnonymousId(); +console.log(uid); // e.g., "a1b2c3d4-e5f6-7890-abcd-ef1234567890" +``` + +**Note:** The ID format is different (UUID v4-like), but serves the same purpose. + +#### Step 4: Event Tracking + +**Before (AppsFlyer):** +```typescript +// Simple event +appsFlyer.logEvent('button_click'); + +// Event with revenue +appsFlyer.logEvent('purchase', { + revenue: 99.99, + currency: 'USD', + product_id: 'prod123', +}); + +// Event with custom parameters +appsFlyer.logEvent('level_complete', { + level: 5, + score: 1000, + time_spent: 120, +}); +``` + +**After (@imtbl/attribution):** +```typescript +// Simple event +attribution.logEvent('button_click'); + +// Event with revenue and parameters (all in properties object) +attribution.logEvent('purchase', { + revenue: 99.99, + currency: 'USD', + product_id: 'prod123', +}); + +// Event with custom parameters +attribution.logEvent('level_complete', { + level: 5, + score: 1000, + time_spent: 120, +}); +``` + +**Key Differences:** +- All event data (including revenue/value) is passed in a single properties object +- Simpler API - no separate value parameter +- More flexible - any property can be included + +#### Step 5: User Identification + +**Before (AppsFlyer):** +```typescript +// Set customer user ID +appsFlyer.setCustomerUserId('user123'); + +// Set user emails +appsFlyer.setUserEmails(['user@example.com'], { + cryptType: 0, // 0 = none, 1 = SHA256 +}); + +// Set additional user data +appsFlyer.setAdditionalData({ + age: 25, + country: 'US', +}); +``` + +**After (@imtbl/attribution):** +```typescript +// Set user ID (same as AppsFlyer) +attribution.setUserId('user123'); + +// Set user email (single email - AppsFlyer supports multiple) +attribution.setUserEmail('user@example.com'); + +// Additional user data should be passed with events +attribution.logEvent('user_profile_updated', { + age: 25, + country: 'US', +}); +``` + +**Note:** Our SDK uses the same user identification model as AppsFlyer (`setUserId`, `setUserEmail`). This is the industry standard approach - separate methods for user ID and email, with additional user data passed via event properties. The main difference is AppsFlyer supports multiple emails with hashing options - for that use case, handle multiple emails in your backend and include them in event properties. + +**Why separate `setUserId`/`setUserEmail` methods?** +- Matches AppsFlyer/Adjust APIs for easy migration +- Clear separation of identity vs. event data +- User ID/email are persistent and sent with every event +- Additional user attributes (age, country, etc.) are event-specific and passed with events + +#### Step 6: Attribution Data + +**Before (AppsFlyer):** +```typescript +// AppsFlyer automatically tracks attribution +// Access via callback or wait for attribution data +appsFlyer.onInstallConversionData((data) => { + console.log('Attribution:', data); + // { + // media_source: 'google', + // campaign: 'summer_sale', + // af_status: 'Non-organic', + // ... + // } +}); +``` + +**After (@imtbl/attribution):** +```typescript +// Attribution is automatically parsed on init +// Access stored attribution data +const attributionData = attribution.getAttributionData(); +console.log(attributionData); +// { +// source: 'google', +// medium: 'cpc', +// campaign: 'summer_sale', +// referrer: 'example.com', +// landingPage: 'https://example.com/?utm_source=google', +// firstTouchTime: 1234567890, +// lastTouchTime: 1234567890, +// custom: { ... } +// } + +// Or parse from a specific URL +const data = attribution.parseAttribution('https://example.com/?utm_source=google'); +``` + +#### Step 7: Page View Tracking + +**Before (AppsFlyer):** +```typescript +// AppsFlyer automatically tracks page views +// Or manually: +appsFlyer.logEvent('page_view', { + page_name: 'homepage', + page_url: window.location.href, +}); +``` + +**After (@imtbl/attribution):** +```typescript +// Enable automatic page view tracking +const attribution = new Attribution({ + trackPageViews: true, // Automatically tracks on init +}); + +// Or manually track page views +attribution.trackPageView('homepage'); +``` + +#### Step 8: Handling Queued Events + +**Before (AppsFlyer):** +```typescript +// AppsFlyer handles event sending automatically +// Events are sent to AppsFlyer servers +``` + +**After (@imtbl/attribution):** +```typescript +// Events are sent immediately (like AppsFlyer) +attribution.logEvent('purchase', { revenue: 99.99 }); + +// If network fails, event is automatically queued and retried +// This happens transparently - no manual queue management needed +``` + +#### Step 9: Deep Linking (Not Supported) + +**Before (AppsFlyer):** +```typescript +// AppsFlyer deep linking +appsFlyer.onDeepLinking((deepLink) => { + console.log('Deep link:', deepLink); +}); +``` + +**After (@imtbl/attribution):** +```typescript +// Deep linking is not supported in this SDK +// Handle deep linking separately in your application +// You can still track deep link events: +attribution.logEvent('deep_link_opened', undefined, { + deep_link_url: window.location.href, +}); +``` + +#### Step 10: Testing Your Migration + +1. **Verify Anonymous ID Generation:** +```typescript +const id = attribution.getAnonymousId(); +console.assert(typeof id === 'string' && id.length > 0, 'ID should be generated'); +``` + +2. **Test Event Tracking:** +```typescript +attribution.logEvent('test_event', 100, { test: true }); +const events = attribution.getQueuedEvents(); +console.assert(events.length > 0, 'Event should be queued'); +console.assert(events[0].eventName === 'test_event', 'Event name should match'); +``` + +3. **Test Attribution Parsing:** +```typescript +// Simulate URL with attribution parameters +const testUrl = 'https://example.com/?utm_source=google&utm_campaign=test'; +const data = attribution.parseAttribution(testUrl); +console.assert(data.source === 'google', 'Source should be parsed'); +console.assert(data.campaign === 'test', 'Campaign should be parsed'); +``` + +#### Migration Checklist + +- [ ] Install `@imtbl/attribution` +- [ ] Replace AppsFlyer initialization with Attribution initialization +- [ ] Update all `getAppsFlyerUID()` calls to `getAnonymousId()` +- [ ] Update all `logEvent()` calls (adjust parameter order if needed) +- [ ] Update `setCustomerUserId()` to `setUserId()` +- [ ] Update `setUserEmails()` to `setUserEmail()` (single email) +- [ ] Replace attribution callbacks with `getAttributionData()` +- [ ] Configure API endpoint for event sending +- [ ] Test anonymous ID persistence across sessions +- [ ] Test event tracking and queuing +- [ ] Test attribution parameter parsing +- [ ] Update backend to handle events from new SDK +- [ ] Remove AppsFlyer SDK dependency + +#### Common Issues and Solutions + +**Issue:** Events not being sent +- **Solution:** `apiEndpoint` is required. Events are sent immediately. If network fails, events are automatically queued and retried when connectivity is restored. Check network connectivity. + +**Issue:** Anonymous ID format is different +- **Solution:** The ID format is different but functionally equivalent. If you need to preserve existing IDs, use `setUserId()` with your existing ID. + +**Issue:** Missing deep linking functionality +- **Solution:** Handle deep linking separately in your application. Track deep link events using `logEvent()`. + +**Issue:** Need to track multiple user emails +- **Solution:** Store multiple emails in your backend. Use `setUserEmail()` for the primary email, and include additional emails in event parameters. + +### Migrating from Adjust Web SDK + +**Before (Adjust):** +```typescript +import { Adjust } from 'adjust-web-sdk'; + +Adjust.init({ + appToken: 'your-app-token', + environment: 'production', // or 'sandbox' +}); + +const adid = Adjust.getAdid(); +Adjust.trackEvent('purchase', { revenue: 99.99 }); +Adjust.setUserId('user123');
