Hello Joseph,
Unfortunately, I don't believe reference attributes are currently supported within the Search Connections API. You may want to create an enhancement request for this behavior.
As an alternative option, you can use the "Get By Crosswalk Connection" API which offers the ability to obtain the related objects of the related object as a separate entities within the response.
Example: Individual > Organization > Affiliated Organization
https://docs.reltio.com/en/explore/get-going-with-apis-and-rocs-utilities/reltio-rest-apis/model-apis/relations-api/get-by-crosswalk-connection
Here is an example Payload Request Body:
"main": {
"inRelations": [
{
"uri": "configuration/relationTypes/OrganizationIndividual"
}
]
},
"nested": [
{
"outRelations": [
{
"uri": "configuration/relationTypes/OrganizationHasAddress"
}
]
},
{
"outRelations": [
{
"uri": "configuration/relationTypes/OrganizationAffiliation"
}
]
}
]
}
