To set up CTV-to-mobile app attribution using cross-platform impression URLs:

1. Create or edit a OneLink template for CTV-to-mobile app attribution.
   • A single template supports your app across multiple operating systems (meaning one template works for Android, iOS, and Windows apps).
   • In the Cross-platform attribution section, make sure you select Enable cross-platform attribution.
2. Enable equal priority for CTV to mobile impressions (optional)  
   1. In AppsFlyer, go to Configuration > Integrated Partners and select the integrated partner.
   2. In the Integration tab, go to the Cross-platform section and enable cross-platform equal attribution priority.
      
   3. Set the Equal attribution priority lookback window
      
      This can be set up to 6 hours. During that time impressions get the same attribution priority as a deterministic click. The app install will be attributed to the cross-platform.
3. Create an attribution link (cross-platform impression URL).
   1. In AppsFlyer, go to Configuration > Integrated Partners and select the integrated partner.
   2. In the Attribution link tab, when creating a OneLink link, select Use OneLink.
   3. Select the OneLink template you created for cross-platform attribution.
   4. Scroll down to View-through attribution.
      

      

   5. Turn on Cross-platform attribution.
      This adds the af_xplatform=true parameter to the impression attribution link and gives the link cross-platform attribution capabilities. Without this parameter, the URL functions as a regular impression URL that can't attribute multiple installs to the same impression.
   6. Set the Cross-platform view-through attribution lookback window.
      This adds the af_xplatform_vt_lookback parameter to the impression attribution link and indicates the number of hours (up to 72) following the impression during which the app install can be attributed to the impression.
   7. Add any additional attribution parameters as needed. Use naming conventions that identify your CTV-to-mobile app campaign. Learn more about the parameters you can add for additional data and metrics.
