SKAdNetwork Reporting API

This new API method enables advertisers to call the Liftoff Direct API and fetch a complete record of all of the Apple SKAdNetwork conversion postbacks that Liftoff has received for their campaigns. The API is for client reporting, and can also be shared with MMP partners for aggregated reporting within their platforms. Refer to our SKAdNetwork for iOS article to learn more about SKAdNetwork attribution.

Key points:

  • Data availability: SKAdNetwork postback data is available as soon as Liftoff servers receive the data sent by Apple.
  • SKAdNetwork campaign mapping: The campaign IDs within these requests are the SKAdNetwork campaign IDs and must be mapped to Liftoff Direct campaign IDs to reconcile with the reporting and performance metrics in the Liftoff Direct Dashboard and in MMP dashboards.
  • Parameters in postbacks: The API response detailed below includes the SKAdNetwork postbacks with parameters exactly as defined by and sent by Apple. The Liftoff Direct API passes these parameters just as we receive them, with no changes.
