When I use the segments endpoint to retrieve the details on a specific segment the segment_criteria is not included. Even the API reference is not returning the segment_criteria field. Here is an example produced by the API reference...
{
"name": "628 - Al E. Orton - Masonic Home Journal List",
"segment_id": 173,
"created_at": "2025-08-21T17:53:06.661240Z"
}
