To set up cross-platform attribution using cross-platform impression URLs:

1. Create or edit a OneLink template for cross-platform attribution.
   • A single template supports your app across multiple operating systems (meaning one template works for across all devices).
   • In the Cross-platform attribution section, click on the edit button -> Enable cross-platform attribution and select all the relevant apps for cross-platform attribution.
     
     

      Note

     For owned media, without an integrated partner go to step 7 as an example for your attribution link. Otherwise continue below.

2. Enable equal priority for cross-platform impressions (optional)  
   1. In AppsFlyer, go to Configuration > Active Integrations 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 > Active Integrations 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 cross-platform app campaign. Learn more about the parameters you can add for additional data and metrics.
      • Example: https://impressions.onelink.me/{template_id}?pid=__media_source__&af_xplatform=true&af_xplatform_vt_lookback=24h&af_siteid=__CSITE__&c=__ctv_to_mobile__&af_channel=__PLACEMENT__&af_c_id=__CAMPAIGN_ID__&af_adset=__AID_NAME__&af_adset_id=__AID__&af_ad=__CID_NAME__&af_ad_id=__CID__&af_source_platform=__source_platform__&af_source_device_category=__device_category__&af_ad_type=__CTYPE__&redirect=false
4. Give the link to the ad network to place behind the ad displayed on CTV.

The list of ad networks that display CTV ads and support CTV-to-mobile app attribution is:

• Smadex
• The Trade Desk
• TVScientific
• Vibe
• Moloco
• MNTN
• Abema TV
• MadHive Inc.
• AJA
• Verve Group
• Samsung DSP
• AppLovin
• Roku OneView
• Mediasmart
• Mintegral

The list is consistently being updated.

AppsFlyer and tvScientific differ in their attribution models. This may cause discrepancies between the tvScientific and AppsFlyer dashboards. See the reasons for discrepancies in the table below:
