Build first-party segments based on mobile advertising IDs

You can use audience pixels in apps to build first-party segments. However, you might need to pass additional parameters to pull in the mobile advertising IDs (AdID or IDFA).

If a mobile app developer uses the Conversion Tracking SDK, the SDK will automatically pull in the mobile advertising IDs. You don’t need to do anything else. Learn more about the SDK in the developer documentation.

If, instead of utilizing the conversion tracking SDK, you use the mobile advertising IDs directly to generate audience pixels, you need to pass two additional parameters:

  • dc_rdid to pass raw IDFA or AdID.

  • dc_lat to pass Limit Ad Tracking signals that a user configured on a device.

    • 1 indicates that the user opts out of audience targeting but opts in to frequency capping.
    • 0 indicates that the user opts in to all tracking.
Note: Make sure to use HTTPS to send the request, to avoid exposing the mobile advertising IDs.

Here’s the sample tag to use for a mobile advertising ID:
