Deep linking is the practice of using a specific URL or URI to send a user directly to a defined destination inside a mobile app, bypassing the home screen. Three link types handle different scenarios: standard deep links (app installed), deferred deep links (app not installed), and contextual deep links (deferred links that also carry metadata through the install).
A studio sends a push notification: “Your support reply is ready.” For a player with the app installed, a standard deep link opens the exact support thread in one tap. For a player who uninstalled and reinstalled, a deferred deep link detects the missing app, redirects to the app store, and drops the player into the same thread on first launch.
Types of Deep Links
| Type | Requires app installed | How it routes |
| Standard | Yes | Uses a custom URI scheme (myapp://) or an HTTPS-based scheme to open the registered in-app screen directly |
| Deferred | No | Redirects to the app store, stores destination intent, and delivers the correct screen on first launch via Install Referrer API (Android) or device fingerprinting (iOS) |
| Contextual | No | A deferred link that also carries metadata (campaign ID, referral source, promo code) through install, personalizing the first session |
HTTPS-based schemes, iOS Universal Links and Android App Links, replaced custom URI schemes because any app could register the same URI string and intercept another app’s links. Server-side domain verification closes that security hole.
How Deep Linking Works
Two routing paths cover the full install spectrum.
Path A: App is installed
- User taps the link.
- The OS checks the app’s registered scheme or verifies the server-hosted configuration file.
- The OS routes the user to the correct in-app screen.
Path B: App is not installed
- The link detects the missing app and redirects to the app store.
- The user completes the install.
- On first launch, the app reads stored destination intent and routes the user to the intended screen.
Two platform files make HTTPS-based routing possible: the Apple App Site Association (AASA) file for iOS Universal Links and the Digital Asset Links JSON file for Android App Links. Both must be hosted at a verified domain and kept current.
Important: An expired or misconfigured AASA file causes iOS to silently fall back to Safari instead of the app, a common production bug that is difficult to detect without active link monitoring.
Deep Links vs. Universal Links
| Dimension | Deep Link (general) | Universal Link (iOS) / App Link (Android) |
| Scope | Broad category covering all link types | Platform-specific HTTPS implementation |
| Security model | Custom URI schemes are hijackable by any app | Server-side file verification ties the link to one verified domain |
| Fallback behavior | Custom URI fails silently if app is absent | Falls back to the associated web URL |
Android App Links are the Android equivalent of iOS Universal Links. Both use HTTPS-based domain verification to prevent URI hijacking and provide a working fallback web destination when the app is absent.
Deep Linking in Player Support Workflows
Three support use cases where deep linking closes the gap between message and action:
- A push notification routes a player directly into their open support thread with agent context already loaded, skipping the home screen entirely.
- A QR code handoff for console players carries them into an active mobile support session without navigation steps. Helpshift’s console-to-mobile QR handoff uses this mechanism to preserve full player context across devices.
- A campaign message drops a player onto a reward claim screen rather than a main menu, removing friction between notification and conversion.
Contextual deep links add attribution value across all three flows. Campaign metadata passes through install, letting studios connect a specific notification or QR scan to downstream outcomes such as ticket resolution or event completion and tie those results back to campaign ROI.
