3. Append advertising identifiers

When your client generates a link for your network, your unique advertising identifier is already appended in the generated link URL. Adjust uses this ID for deterministic attribution, which increases accuracy and is the easiest and most secure way for us to attribute users.

Note:
Adjust can use probabilistic modeling to measure conversions, which uses certain variables that can change and expire. This may cause conversions to be under-reported. If your client would like to use probabilistic modeling for attribution, they must enable it in the attribution settings. Probabilistic modeling is turned OFF by default.

Examples

We accept most advertising IDs and hashes. Advertising IDs are passed using Adjust parameters.

Here's an example of a link URL with an advertising identifier added, with a link token and campaign structure parameters already attached:

https://app.adjust.com/abc123?campaign={publisher_id}&adgroup={sub_publisher_id}&creative={creative_id}&gps_adid=(your_identifier_macro)

Here's an example of a link URL for an iOS app with the advertising parameter for IDFA, a link token and campaign structure parameters appended:

https://app.adjust.com/abc123?campaign={publisher_id}&adgroup={sub_publisher_id}&creative={creative_id}&idfa=(your_identifier_macro)

Device IDs

Important:
  • Adjust only uses the Android ID for attribution when the gps_adid is unavailable.
  • The IDFV can be used when running cross-promotional campaigns among your own apps, for example via email, push notification, or deep links. The IDFV provides more accurate attribution than only relying on probabilistic modeling.
