CustomFieldLists for Setting Custom Segment Values
Custom segments are custom classification fields similar to class, department, and location. When the Custom Segments feature is enabled, an administrator working in the UI can create custom segments, define possible values for each segment, and apply the segments to specific record types. Each custom segment appears as a field on instances of record types where the segment was applied. Users can then classify records by selecting the appropriate value for each segment.
When working with records in SOAP web services, you can in many cases set values for segments that may appear as fields on those records. Specifically, if the record type’s exposure includes a CustomFieldList, you can set segment values on instances of that record type. To set values, you define a CustomFieldList for the record instance. You can then use the list to set values for one or more segments.
