React Native: Migrating from Firebase Dynamic Links to Branch.io (Complete Implementation Guide)
With Firebase's announcement of Dynamic Links deprecation coming in August 2025, React Native developers are faced with an urgent need to migrate their deep linking infrastructure. As we covered in our previous articles about Firebase's Dynamic Links Deprecation Impact and Evaluating Firebase Dynamic Links Alternatives, this migration presents both challenges and opportunities for mobile developers.
This comprehensive guide will walk through replacing Firebase Dynamic Links with Branch.io in a React Native application, providing a complete technical pathway from evaluation to implementation and testing.
Understanding the Migration Landscape
According to Stack Overflow's 2025 Developer Survey, nearly 47% of mobile app developers have used Firebase Dynamic Links as their primary deep linking solution, making this deprecation a significant industry event. Forums like XDA Developers and Reddit's r/programming have been abuzz with migration discussions, with Branch.io emerging as one of the most popular alternatives.
As noted by Ars Technica's technical forum, Branch.io has gained popularity due to its robust feature set that extends beyond Firebase's basic functionality, along with a reliable API that many developers find more intuitive. Let's dive deeper into the differences between these platforms.
Comparing Firebase Dynamic Links and Branch.io
Before beginning the migration, understanding the key differences between Firebase Dynamic Links and Branch.io will help inform your implementation strategy.
Feature | Firebase Dynamic Links | Branch.io |
Pricing Model | Free tier with limits | Free tier with premium options |
Deep Linking | ✓ | ✓ |
Deferred Deep Linking | ✓ | ✓ |
Click Analytics | Basic | Advanced |
A/B Testing | Limited | Comprehensive |
Integration Complexity | Moderate | Low to Moderate |
Custom Domains | ✓ | ✓ |
Link Attribution | Basic | Advanced |
Fraud Prevention | Limited | Advanced |
User Journey Tracking | Limited | Comprehensive |
API Stability | Deprecating | Stable |
According to reports from The Verge and TechCrunch, Branch.io's particular strengths lie in its more reliable attribution model and cross-platform consistency, which can be crucial for apps that need precise campaign tracking.
Migration Preparation Checklist
Before diving into code, prepare your migration with this checklist derived from best practices discussed on Hacker News and GitHub's engineering blog:
Audit Existing Implementation
: Document all use cases of Firebase Dynamic Links in your React Native app
Identify Integration Points
: Map all places in codebase that initialize, create, or process dynamic links
Document URL Patterns
: List all URL formats and parameters currently in use
Analytics Inventory
: Catalog what tracking and attribution data you currently use
Test Environment Setup
: Create a separate testing environment for migration
Backup Plans
: Establish fallback strategies for critical user journeys
Timeline Establishment
: Create a detailed migration schedule with QA checkpoints
Team Training
: Ensure your team understands Branch.io's concepts and implementation
Stakeholder Communication
: Prepare announcements for users if there will be visible changes
As noted in Smashing Magazine's article on frontend migrations, this preparation phase is often underestimated but critical for a smooth transition.
Setting Up Branch.io in React Native
Let's start by implementing Branch.io in your React Native project:
1. Installation
# Using npm
npm install react-native-branch --save
# Using yarn
yarn add react-native-branch
2. iOS Setup
For iOS, you'll need to make changes to your Podfile and Info.plist:
# Podfile
target 'YourApp' do
# ... other dependencies
pod 'Branch', '~> 1.43.0'
end
Run pod install
to install the iOS dependencies.
Update your Info.plist file to include:
<key>branch_key</key>
<dict>
<key>live</key>
<string>key_live_xxxxxxxxxxxxxxxxxxxxxxx</string>
<key>test</key>
<string>key_test_xxxxxxxxxxxxxxxxxxxxxxx</string>
</dict>
<key>branch_universal_link_domains</key>
<array>
<string>yourapp-alternate.app.link</string>
<string>yourapp.app.link</string>
<string>your-custom-domain.com</string> <!-- If using a custom domain -->
</array>
For Associated Domains, update your Entitlements file:
<key>com.apple.developer.associated-domains</key>
<array>
<string>applinks:yourapp.app.link</string>
<string>applinks:yourapp-alternate.app.link</string>
<string>applinks:your-custom-domain.com</string> <!-- If using a custom domain -->
</array>
3. Android Setup
For Android, update your android/app/build.gradle
with:
android {
defaultConfig {
// ... other config
manifestPlaceholders = [
branchKey: "key_live_xxxxxxxxxxxxxxxxxxxxxxx",
branchTestKey: "key_test_xxxxxxxxxxxxxxxxxxxxxxx"
]
}
}
Add the required intent filter to your AndroidManifest.xml
:
<intent-filter android:autoVerify="true">
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.BROWSABLE" />
<data android:scheme="https" android:host="yourapp.app.link" />
<data android:scheme="https" android:host="yourapp-alternate.app.link" />
<data android:scheme="https" android:host="your-custom-domain.com" /> <!-- If using custom domain -->
</intent-filter>
4. Initialize Branch.io
In your React Native app's entry point (likely App.js
or index.js
):
import branch from 'react-native-branch';
// Initialize Branch as early as possible
branch.setup();
// Listen for deep links
branch.subscribe(({ error, params, uri }) => {
if (error) {
console.error('Branch Error: ', error);
return;
}
if (params['+non_branch_link']) {
// Handle non-Branch links here
return;
}
if (!params['+clicked_branch_link']) {
// Not a Branch link
return;
}
// A Branch link was opened
console.log('Branch link opened: ', params);
// Handle the deep link based on params
if (params.$deeplink_path) {
// Handle route specified in $deeplink_path
handleDeepLink(params.$deeplink_path, params);
} else if (params.route) {
// Custom parameter we might have added
handleDeepLink(params.route, params);
}
});
// Define a function to handle the deep link
function handleDeepLink(route, params) {
// Your navigation logic here
// Example:
switch(route) {
case 'product':
navigateToProduct(params.productId);
break;
case 'profile':
navigateToProfile(params.userId);
break;
// etc.
}
}
According to AnandTech forums, initializing Branch early in your application lifecycle is crucial for capturing all potential deep link openings, particularly for cold starts.
Implementing Deep Links with Branch.io
Now that Branch.io is set up, let's implement the core deep linking functionality to replace Firebase Dynamic Links.
Creating Branch Links
import branch from 'react-native-branch';
// Function to create a shareable Branch link
export async function createBranchLink(params) {
const branchUniversalObject = await branch.createBranchUniversalObject('product/123', {
locallyIndex: true,
title: params.title || 'Product Title',
contentDescription: params.description || 'Product Description',
contentMetadata: {
customMetadata: {
productId: params.productId,
category: params.category,
// Add any other custom data
}
}
});
const linkProperties = {
feature: 'sharing',
channel: params.channel || 'facebook',
campaign: params.campaign || 'product_launch'
};
const controlParams = {
$desktop_url: 'https://yourwebsite.com/product/' + params.productId,
$ios_url: 'https://apps.apple.com/app/yourapp/id123456789',
$android_url: 'https://play.google.com/store/apps/details?id=com.yourcompany.yourapp',
$fallback_url: 'https://yourwebsite.com/fallback',
$deeplink_path: 'product/' + params.productId,
route: 'product', // Custom parameter
productId: params.productId, // Custom parameter
};
try {
const { url } = await branchUniversalObject.generateShortUrl(linkProperties, controlParams);
return url;
} catch (error) {
console.error('Error generating Branch link:', error);
throw error;
}
}
Handling Deep Links in Navigation
For React Navigation 6.x:
import * as React from 'react';
import { NavigationContainer } from '@react-navigation/native';
import { createStackNavigator } from '@react-navigation/stack';
import branch from 'react-native-branch';
// Import your screens
import HomeScreen from './screens/HomeScreen';
import ProductScreen from './screens/ProductScreen';
import ProfileScreen from './screens/ProfileScreen';
const Stack = createStackNavigator();
function App() {
const [initialRoute, setInitialRoute] = React.useState('Home');
const [initialParams, setInitialParams] = React.useState({});
const [isReady, setIsReady] = React.useState(false);
React.useEffect(() => {
// Set up Branch deep link handler
const branchSubscription = branch.subscribe(({ error, params }) => {
if (error) {
console.error('Branch Error: ', error);
return;
}
if (params['+clicked_branch_link']) {
// Extract navigation info from Branch params
if (params.route === 'product' && params.productId) {
setInitialRoute('Product');
setInitialParams({ productId: params.productId });
} else if (params.route === 'profile' && params.userId) {
setInitialRoute('Profile');
setInitialParams({ userId: params.userId });
}
}
setIsReady(true);
});
// Clean up subscription
return () => branchSubscription();
}, []);
if (!isReady) {
// Show a loading screen until Branch finishes processing
return <LoadingScreen />;
}
return (
<NavigationContainer>
<Stack.Navigator initialRouteName={initialRoute}>
<Stack.Screen name="Home" component={HomeScreen} />
<Stack.Screen
name="Product"
component={ProductScreen}
initialParams={initialRoute === 'Product' ? initialParams : undefined}
/>
<Stack.Screen
name="Profile"
component={ProfileScreen}
initialParams={initialRoute === 'Profile' ? initialParams : undefined}
/>
</Stack.Navigator>
</NavigationContainer>
);
}
This pattern of navigation handling is recommended by multiple developers on the React Native GitHub forums and Stack Overflow, providing a clean way to integrate Branch.io's deep linking with React Navigation.
URL Configuration and Structure Migration
One key challenge noted in TechCrunch's developer interviews is maintaining consistent URL patterns when migrating from Firebase to Branch.io. Here's how to approach it:
Branch Link Domain Configuration
Set up a custom domain (optional but recommended):
Configure a subdomain (e.g.,
links.yourapp.com
) to use with Branch.io
Update DNS records as per Branch.io documentation
Verify domain ownership in the Branch.io dashboard
Create Matching Link Templates:
Analyze your existing Firebase Dynamic Links URL patterns
Create corresponding templates in Branch.io
URL Pattern Migration Examples
Here's how to map common Firebase Dynamic Link patterns to Branch.io:
Firebase URL format:
https://yourapp.page.link/?link=https://yourwebsite.com/product/123&apn=com.yourcompany.yourapp&isi=123456789&ibi=com.yourcompany.yourapp
Equivalent Branch.io implementation:
const linkData = {
productId: '123',
route: 'product'
};
const linkProperties = {
feature: 'product_sharing'
};
const controlParams = {
$deeplink_path: 'product/123',
$desktop_url: 'https://yourwebsite.com/product/123',
$android_package_name: 'com.yourcompany.yourapp',
$ios_bundle_identifier: 'com.yourcompany.yourapp',
$ios_url: 'https://apps.apple.com/app/yourapp/id123456789'
};
branch.createBranchUniversalObject('product/123', {
title: 'Product Title',
contentDescription: 'Product Description',
contentMetadata: {
customMetadata: linkData
}
})
.then(branchUniversalObject => {
branchUniversalObject.generateShortUrl(linkProperties, controlParams)
.then(({ url }) => {
console.log('Generated Branch link: ', url);
// Result would be something like: https://yourapp.app.link/AbCdEfGhIj
// Or with custom domain: https://links.yourapp.com/AbCdEfGhIj
});
});
According to data from Dev.to community discussions, maintaining consistent URL structures is crucial for preserving SEO value and ensuring backward compatibility with existing links in the wild.
Analytics and Attribution Migration
One area where Branch.io particularly excels over Firebase Dynamic Links is in analytics capabilities. Let's implement a comprehensive analytics migration:
Setting Up Basic Link Analytics
// When creating a link, set appropriate analytics parameters
const linkProperties = {
feature: 'share', // The feature you're using the link in
channel: 'facebook', // The channel this link is shared on
campaign: 'summer_promotion', // Marketing campaign
stage: 'new_user', // Customer journey stage
tags: ['2025launch', 'featured'] // Custom tags
};
Tracking Events with Branch.io
import branch from 'react-native-branch';
// Track standard events
export function trackPurchase(transactionID, amount, currency, items) {
branch.logEvent(
branch.BranchEvent.Purchase, {
transactionID,
currency,
revenue: amount,
shipping: 0,
tax: 0,
coupon: 'SUMMER25',
affiliation: 'web_store',
description: 'User completed purchase',
searchQuery: '',
items: items.map(item => ({
productName: item.name,
productBrand: item.brand,
price: item.price,
quantity: item.quantity,
productCategory: item.category,
productVariant: item.variant,
sku: item.sku
}))
}
);
}
// Track custom events
export function trackCustomEvent(eventName, eventData) {
const event = new branch.BranchEvent(
branch.BranchEvent.CustomEvent,
eventName
);
Object.entries(eventData).forEach(([key, value]) => {
event.customData[key] = value;
});
event.logEvent();
}
// Example usage
trackCustomEvent('user_rated_product', {
productId: '123',
rating: 4.5,
reviewContent: 'Great product!',
userLevel: 'premium'
});
Implementing Deep Link Analytics Handler
// In your deep link handler
branch.subscribe(({ error, params }) => {
if (error) {
console.error('Branch Error: ', error);
return;
}
if (params['+clicked_branch_link']) {
// Log information about the link click
trackCustomEvent('deep_link_opened', {
linkData: JSON.stringify(params),
source: params.channel || 'unknown',
campaign: params.campaign || 'none',
linkCreationDate: params['+created_timestamp']
? new Date(params['+created_timestamp'] * 1000).toISOString()
: 'unknown'
});
// Track specific journeys
if (params.route === 'product') {
trackCustomEvent('product_deep_link_opened', {
productId: params.productId,
referringSource: params.channel
});
}
}
});
According to Wilder Security Forums and MIT Technology Review's analysis, this level of granular analytics enables significantly better attribution and user journey tracking than what was possible with Firebase Dynamic Links.
Testing Your Branch.io Implementation
A rigorous testing strategy is essential for a successful migration. Based on best practices from the QA community on SitePoint Forums, here's a comprehensive testing approach:
1. Test Link Creation
// Test utility for link creation
async function testLinkCreation() {
try {
const testParams = {
productId: '12345',
title: 'Test Product',
description: 'Testing Branch link creation',
channel: 'test'
};
const url = await createBranchLink(testParams);
console.log('Successfully created test link:', url);
// Verify link works by opening it
const linkOpened = await branch.openURL(url);
console.log('Link open result:', linkOpened);
return true;
} catch (error) {
console.error('Link creation test failed:', error);
return false;
}
}
2. Test Deep Link Handling
Create a comprehensive test suite that covers all your deep linking scenarios:
// Deep link testing utility
export const BranchLinkTester = {
testCases: [
{
name: 'Product Detail',
params: {
$deeplink_path: 'product/123',
route: 'product',
productId: '123'
},
expectedRoute: 'Product',
expectedParams: { productId: '123' }
},
{
name: 'User Profile',
params: {
$deeplink_path: 'profile/456',
route: 'profile',
userId: '456'
},
expectedRoute: 'Profile',
expectedParams: { userId: '456' }
},
// Add more test cases as needed
],
// Run all tests
async runTests() {
const results = [];
for (const testCase of this.testCases) {
console.log(`Running test: ${testCase.name}`);
try {
// Create a test Branch Universal Object
const buo = await branch.createBranchUniversalObject(
`test/${Date.now()}`,
{ contentMetadata: { customMetadata: testCase.params } }
);
// Generate a test link
const { url } = await buo.generateShortUrl({}, testCase.params);
// Store for manual testing
results.push({
name: testCase.name,
testUrl: url,
status: 'Generated',
expectedRoute: testCase.expectedRoute,
expectedParams: testCase.expectedParams
});
console.log(`Test ${testCase.name} - URL generated: ${url}`);
} catch (error) {
results.push({
name: testCase.name,
status: 'Failed',
error: error.message
});
console.error(`Test ${testCase.name} failed:`, error);
}
}
return results;
}
};
3. Test Across Environments and Conditions
Based on real-world testing scenarios from AnandTech Forums, ensure you test across these conditions:
Fresh Install Tests
- Test links when app is not yet installed
Background State Tests
- Test when app is in background
Different OS Versions
- Test on multiple iOS and Android versions
Network Condition Tests
- Test under poor connectivity
Time-Delay Tests
- Test links opened after several days
Cross-Platform Tests
- Test links created on one platform and opened on another
Performance Benchmarking
According to SitePoint Forums and Stack Overflow discussions, performance comparisons between Firebase Dynamic Links and Branch.io are important. Here's a benchmarking utility:
import branch from 'react-native-branch';
import { PerformanceObserver, performance } from 'react-native-performance';
class DeepLinkBenchmark {
constructor(iterations = 10) {
this.iterations = iterations;
this.firebaseResults = [];
this.branchResults = [];
}
// Benchmark Branch.io link creation
async benchmarkBranchLinkCreation() {
const results = [];
for (let i = 0; i < this.iterations; i++) {
const startTime = performance.now();
try {
const buo = await branch.createBranchUniversalObject(`benchmark/item${i}`, {
title: 'Benchmark Item',
contentMetadata: {
customMetadata: {
testId: `test-${i}`,
iteration: i
}
}
});
await buo.generateShortUrl();
const endTime = performance.now();
results.push(endTime - startTime);
} catch (error) {
console.error('Branch benchmark error:', error);
}
}
return {
average: results.reduce((sum, time) => sum + time, 0) / results.length,
median: results.sort()[Math.floor(results.length / 2)],
min: Math.min(...results),
max: Math.max(...results)
};
}
// Benchmark Branch.io link resolution
async benchmarkBranchLinkResolution(testUrl) {
const results = [];
for (let i = 0; i < this.iterations; i++) {
const startTime = performance.now();
try {
await branch.openURL(testUrl);
const endTime = performance.now();
results.push(endTime - startTime);
} catch (error) {
console.error('Branch resolution benchmark error:', error);
}
}
return {
average: results.reduce((sum, time) => sum + time, 0) / results.length,
median: results.sort()[Math.floor(results.length / 2)],
min: Math.min(...results),
max: Math.max(...results)
};
}
// Generate report
async generateReport() {
console.log('Starting benchmark tests...');
// First create a test link
const buo = await branch.createBranchUniversalObject('benchmark/main', {
title: 'Benchmark Test',
contentMetadata: {
customMetadata: {
benchmarkTest: true
}
}
});
const { url } = await buo.generateShortUrl();
const creationResults = await this.benchmarkBranchLinkCreation();
const resolutionResults = await this.benchmarkBranchLinkResolution(url);
return {
linkCreation: creationResults,
linkResolution: resolutionResults,
testUrl: url
};
}
}
// Usage
const benchmark = new DeepLinkBenchmark(20);
benchmark.generateReport().then(report => {
console.log('Benchmark Report:', JSON.stringify(report, null, 2));
});
Based on benchmarks shared on AnandTech Forums, Branch.io typically shows 15-20% faster link resolution times compared to Firebase Dynamic Links, particularly on Android devices.
Gradual Rollout Strategy
According to technical case studies from The Information, a phased migration approach is recommended for high-traffic apps. Here's a gradual rollout strategy based on best practices:
Phase 1: Parallel Implementation (2-4 weeks)
Implement Branch.io alongside existing Firebase Dynamic Links
Send 10% of new link creation traffic to Branch.io
Instrument detailed logging and error reporting
Focus on core use cases only
Phase 2: Expanded Testing (2-4 weeks)
Increase Branch.io traffic to 25-50%
Add all secondary use cases
Implement comprehensive A/B testing
Compare performance and error rates
Begin user education if interface changes exist
Phase 3: Primary Migration (2-4 weeks)
Switch to 90% Branch.io traffic
Keep Firebase as fallback only
Complete all analytics integrations
Finalize documentation and developer guidance
Phase 4: Complete Cutover (1-2 weeks)
Remove Firebase Dynamic Links code
Complete final QA pass
Update all documentation
Archive Firebase dashboard data
VentureBeat and TechRepublic's migration case studies suggest this phased approach significantly reduces the risk of user-facing issues during the transition.
Troubleshooting Common Issues
From analyzing GitHub and Stack Overflow discussions, here are solutions to the most common issues encountered during migration:
1. iOS Universal Links Not Working
Problem: Branch.io links do not open the app on iOS.
Solution:
Verify your Apple App Site Association (AASA) file is properly configured
Check that entitlements are correctly set up:
<key>com.apple.developer.associated-domains</key>
<array>
<string>applinks:yourapp.app.link</string>
<string>applinks:yourapp-alternate.app.link</string>
<string>applinks:your-custom-domain.com</string>
</array>
Clear the app from recent apps and reinstall
Test with a new link (iOS caches previous link failures)
2. Android App Links Not Verified
Problem: Android shows a disambiguation dialog instead of directly opening the app.
Solution:
Ensure your AndroidManifest.xml contains
android:autoVerify="true"
Verify Digital Asset Links file on your domain
Check that your intent filter is correctly configured:
<intent-filter android:autoVerify="true">
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.BROWSABLE" />
<data android:scheme="https" android:host="yourapp.app.link" />
<data android:scheme="https" android:host="yourapp-alternate.app.link" />
</intent-filter>
For testing, use adb to check verification status:
adb shell dumpsys package d
3. Link Parameters Not Being Received
Problem: Deep link opens the app but parameters are missing.
Solution:
Ensure Branch is initialized early in the app lifecycle
Check that you're handling the correct parameter names
Review Branch dashboard to see what data is being passed
Common parameter key differences:
// Firebase parameter access
const productId = dynamicLink.queryParameters['product_id'];
// Equivalent Branch.io access
const productId = branchParams.productId || branchParams['~referring_link'].searchParams.get('product_id');
4. Delayed Deep Linking Issues
Problem: Deferred deep linking (when app is not installed) doesn't work.
Solution:
Check that you've implemented the full Branch initialization
On iOS, verify your team ID and bundle ID match your Branch settings
On Android, confirm your package name is correct in Branch dashboard
Test with a completely fresh device or emulator (installation tracking cookies)
5. Analytics Discrepancies
Problem: Analytics data doesn't match what you had in Firebase.
Solution:
Branch uses different attribution models than Firebase
Implement a dual tracking period with both systems
Create mapping documentation for translating between analytics labels
For exact metrics matching, consider custom event tracking
Branch.io Advanced Features
According to TechCrunch and ZDNet's analysis, Branch.io offers several advanced capabilities beyond what Firebase Dynamic Links provided. Here's how to implement some of these features:
1. Journey Banners and Smart Banners
Branch.io's Smart Banners can replace Firebase's app banner functionality:
import branch from 'react-native-branch';
// Show the Journey banner
branch.showShareSheet(
{
feature: 'banner',
channel: 'app_banner'
},
{
$journeyId: 'your_journey_id',
$3p: 'a_three_letter_branch_id'
}
);
These banners can be configured in the Branch.io dashboard with sophisticated targeting options.
2. Content Analytics
Branch.io's content analytics provide deeper insights than Firebase:
// Create a rich content object
const branchUniversalObject = await branch.createBranchUniversalObject('item/123', {
title: 'Item Title',
contentDescription: 'Item Description',
contentImageUrl: 'https://example.com/image.jpg',
contentMetadata: {
price: 29.99,
sku: 'SKU123',
quantity: 1,
productBrand: 'Brand Name',
productCategory: 'Category',
productName: 'Product Name',
productVariant: 'Variant',
rating: 4.8,
ratingAverage: 4.8,
ratingCount: 354,
ratingMax: 5,
addressStreet: '123 Example St',
addressCity: 'San Francisco',
addressRegion: 'CA',
addressCountry: 'US',
addressPostalCode: '94107',
latitude: 37.7749,
longitude: -122.4194,
imageCaptions: ['Front', 'Side', 'Back']
}
});
// Track when content is viewed
branchUniversalObject.logEvent(BranchEvent.ViewItem);
3. QR Code Generation
Branch.io supports QR code generation, which Firebase Dynamic Links required additional integrations for:
// After generating a Branch link
const branchUniversalObject = await branch.createBranchUniversalObject('qr/product/123', {
title: 'QR Code Demo',
contentMetadata: {
customMetadata: {
productId: '123'
}
}
});
const linkProperties = { feature: 'qr_code', channel: 'app' };
const controlParams = { $desktop_url: 'https://yoursite.com/product/123' };
const { url } = await branchUniversalObject.generateShortUrl(linkProperties, controlParams);
// Generate QR Code URL
const qrCodeUrl = `https://api.branch.io/v1/qr-code?url=${encodeURIComponent(url)}&size=500`;
// Now you can use this QR code URL in an image component
<Image source={{ uri: qrCodeUrl }} style={{ width: 250, height: 250 }} />
4. Attribution Windows Configuration
Branch.io offers more granular attribution window configuration:
// Set attribution window
branch.setRequestMetadata('$attribution_window', '30d');
Case Study: Migration Success Story
A real-world example from The Information highlights how a major e-commerce app with 5M+ installs migrated from Firebase Dynamic Links to Branch.io with impressive results.
The company followed a similar approach to what we've outlined above and achieved:
