What is OneLink?
OneLink is AppsFlyer's cross-platform attribution & deep linking solution that routes users to the right destination regardless of device.

Mobile apps added to your AppsFlyer dashboard (iOS and/or Android).
AppsFlyer SDK integrated in your mobile apps (recommended for full attribution)
Step 1: Create a OneLink Template for Cross-Platform Attribution
A single template supports your app across multiple platforms, meaning one template works across all platforms.

Click the menu icon (three dots) in the top-right corner.
Select Add OneLink template.
Template Setup:
Template Name: Enter a descriptive name (e.g., "TvScientific_CTV_Campaign")
Subdomain: Choose a subdomain for your links (e.g., "yourapp.onelink.me")
Platform Selection: Select both your iOS and Android apps
Step 2: Enable Cross-Platform Attribution
This is the critical step for TvScientific CTV campaigns:
In the Cross-platform attribution section, click the edit button.
Toggle Enable cross-platform attribution.
From the relevant platform drop-downs, select your apps:
Select your iOS app
Select your Android app
Important Note: Each app can only be added to one OneLink template with cross-platform attribution enabled.
