Hi @rob2020
In the same document you'll see the way to pass mbox parameters into API request.
Most fields in the XDM portion of each request are serialized into dot notation and then sent to Target as custom or mbox parameters.
Example
Given the following XDM sample:
"xdm":{
"marketing":{
"campaignGroup":"winter22",
"campaignName":"homeOwnerPromo22",
"trackingCode":"hop22"
}
}
When creating audiences in Target, the following values will be available as custom parameters:
- xdm.marketing.campaignGroup
- xdm.marketing.campaignName
- xdm.marketing.trackingCode
