About Custom IDs
In order to use a custom, publisher-provided identifier within ATS, you will need to send LiveRamp a mapping file on a regular basis. See Custom ID Support to learn more.
When using custom ids you must pass the following values within the iv parameter:
ANA_ID:CUSTOM_ID
Where the ANA_ID represents the Account ID and CUSTOM_ID represents your custom identifier.
