Passing post-install events to Unity

Secondary conversion endpoint integration

Event parameters help refine Unity’s machine learning algorithm and improve campaign performance. Audience Pinpointer campaigns require session event data for retention optimization campaigns, and purchase event data for revenue optimization campaigns (for more information, see the Required Audience Pinpointer event parameters section below). Implement these post-install event callbacks through your third-party attribution partner.

Required Audience Pinpointer event parameters

You must include the following components with your event query for Audience Pinpointer campaigns.

Component Parameter
Base URL https://ads-secondary-conversion.unityads.unity3d.com/v1/events
User identification One of the following:

  • ifa={iOS Identifier for advertising in iOS} (required for ios; also accepts idfa)
  • aid={Google Play Advertising Identifier} (required for android)
  • android_id_md5={md5 hash of lowercase android id}
  • gamer_id={Unity Ads gamer id} (if available)
Note: Both iOS and Android accept advertising IDs in uppercase or lowercase, but iOS converts to uppercase, while Android converts to lowercase.
Ad tracking setting tracking_enabled={1|0} or tracking_limited={1|0}
Campaign ID campaign_id={Unity Ads campaign ID}
Game identification game_id={Unity Ads Game ID} (required; locate this on the main page of the advertising dashboard, listed under your game’s title)

Plus one of the following:

  • platform={ios|android}&store_id={itunes id|googleplay id}
  • platform={ios|android}&bundle_id={bundle id}
  • platform={ios|android}&project_id={Unity Project ID}
Accepted values for iOS include ios, itunes, iOS, and iTunes.

Accepted values for Android include android, google, Android, Google, gplay, and GooglePlay.
Original install timestamp install_ts={unix time in seconds or milliseconds}
Event identification Identify which event was triggered by the user:

event={event name}, where the event name is one of the following:
  • session (user started a gameplay session; required for retention optimization campaigns)
  • purchase (user purchased something via IAP) and value={amount}&currency={currency} (both required for revenue optimization campaigns. Amount must be in decimal point, for example 1.23)
Original conversion attributed? Indicate whether the original conversion of this user has been attributed to this network or not:

was_conversion_attributed=1

Optional event parameters

Include the following optional components with your event query to help improve campaign performance.

Component Parameter
Timestamp ts={unix time in seconds or milliseconds}

When the event happened. By default, the event happened at (or near) the time it was fired to the endpoint.
Event identification If the event is not a session or purchase event:

event={event name}, where the event name is one of the following:
  • registration (user registered to the app)
  • spent_credits (user spent virtual currency to buy in-game items), along with value={how many credits} (optional) and type={what type credits} (optional)
  • invite (user invited friends to the game)
  • share (user shared the game with friends)
  • level_complete (user completed a level), along with value={level name} (optional)
  • tutorial_complete (user completed the tutorial)
  • achievement_unlocked (user unlocked an achievement)
  • custom (a custom event), along with custom_event={custom_event_name} and value={value}&type={type} (optional)
Test mode test=1

This is a test event being fired to the service. It does not count as a real event from end users.
