How Does an App Remember Where to Navigate After Installation? — Understanding Deferred Deep Linking

Imagine this.

You’re browsing Amazon and your friend sends you a link to a pair of headphones. You click on it, but you don’t have the Amazon app installed.

You’re redirected to the Play Store. You install the application and open it for the very first time.

Surprisingly, you’re not taken to the home screen. You’re looking at the exact product your friend shared just a few moments ago.

No searching, No extra clicks, No “Continue” button.

Just a seamless experience.

Have you ever wondered how the application knew where to navigate?

More importantly, where did the original link go during the installation process?

That’s the question that led me to explore Deferred Deep Linking.

Let’s start with normal Deep Linking.

Things are pretty straightforward when the application is already installed.

Click Link → Open App → Receive URL → Navigate

React Native makes this extremely simple using the Linking API.

Now let’s assume

Click Link → App isn’t installed → Redirected to Play/App Store → Install App → Open App → ??? → Navigate

Did you notice the problem?

Somewhere between leaving our browser and opening the application, we’ve lost the original context. The moment users are redirected to the Play Store or App Store, they’ve effectively left our application’s ecosystem.

At this point, several questions arise:

• Which product did they click?
• Which campaign brought them here?
• How do we preserve that information during installation?
• How do we identify the same user after installation?
• How does the application retrieve that information on its first launch?

Deferred Deep Linking exists to solve exactly these problems.

Deep Linking = Navigation

Deferred Deep Linking = Navigation + Attribution + Context Preservation

Preserving a user’s intent throughout the installation lifecycle is where things become interesting.

Let’s follow what actually happens behind the scenes.

User Flow

Step 1: User Clicks a Link

Suppose a user clicks:

https://example.com/product/123

At this point, the user could have arrived from:

• Social media
• Marketing campaigns
• Email links
• Referral programmes
• Advertisements
• QR codes

The link itself contains valuable information that we don’t want to lose.

For example:

Product ID
Campaign ID
Referral Code
Medium
Timestamp
Source

This information becomes extremely important later in the flow.

Step 2: Preserving Context

Before redirecting users to the App Store or Play Store, the system preserves the necessary context.

For example:

{
    productId: 123,
    campaign: "summer-sale",
    medium: "social",
    referralCode: "ABC123"
}

This information can be:

• Stored by attribution services
• Preserved using backend systems
• Associated with tokens or identifiers
• Retrieved later during application launch

At this point, the system’s responsibility changes.

Instead of asking:

Where should users navigate?

We’re now asking:

How do we remember what users intended to do?

Step 3: The Journey Through Installation

The user is now redirected to:

Play Store
   OR
 App Store

The application is installed and launched for the very first time.

This creates another interesting challenge.

Browser
   ↓
Play Store
   ↓
Installation
   ↓
Application Launch

Notice something?

There is no direct communication happening between:

• The original browser session
• The App Store
• The application’s first launch

Some mechanism must bridge this gap.

This is where attribution systems become extremely important.

What Happens Behind The Scenes?

There isn’t a single implementation for Deferred Deep Linking.

Different mechanisms can work together depending upon the application’s requirements.

Some commonly used approaches include:

Android

• Install Referrer API
• Android App Links
• Attribution SDKs

iOS

• Universal Links
• Attribution APIs
• Native SDK integrations

Backend Services

• Token mapping
• Context preservation
• Campaign tracking
• Analytics services

The overall flow looks something like this:

Store Metadata
      ↓
Install Application
      ↓
Retrieve Attribution Data
      ↓
Initialize SDK
      ↓
Receive Deep Link Parameters
      ↓
Navigate

Regardless of the implementation, the objective remains the same:

Preserve the user’s original intent.

How React Native Fits Into The Picture

One common misconception is that React Native implements Deferred Deep Linking.

It doesn’t.

React Native’s responsibility begins only after the pending information becomes available.

A simplified flow looks like this:

Native Layer
      ↓
Retrieves Deep Link Data
      ↓
 React Native Bridge
      ↓
 Javascript Thread
      ↓
Navigation Layer
      ↓
 Navigate to Screen

Once the native layer retrieves the required information, it can pass the parameters to the JavaScript layer, allowing the navigation system to redirect users appropriately.

For example:

• Product Screen
• Referral Screen
• Offer Screen
• Profile Screen
• Promotional Campaigns

React Native isn’t preserving the user’s intent.

It’s simply consuming the information once it becomes available.

Understanding this distinction makes it much easier to reason about Deferred Deep Linking during system design discussions.

Production Considerations

Real-world applications introduce additional complexities.

Some questions worth thinking about are:

• What if users aren’t authenticated?
• What if SDK initialisation fails?
• What if users kill the application during navigation?
• What happens when campaigns expire?
• Should pending links be preserved after login?
• How should analytics events be tracked?

Consider the following scenario.

User opens application
          ↓
 Deferred link retrieved
          ↓
 Is user authenticated?
        /      \
      No       Yes
      ↓         ↓
 Navigate     Product Page
  to Login
      ↓
Successful Login
      ↓
Retrieve Pending Link
      ↓
Navigate

In many production systems, pending links are temporarily stored until authentication is completed.

Only after successful authentication do we perform the final navigation.

This significantly improves the overall user experience.

Similarly, systems should also consider:

• Offline scenarios
• Multiple pending links
• Failed attribution requests
• Application updates
• Analytics and campaign tracking

These considerations are often what differentiate production-ready implementations from simple demonstrations.
