Get only the relationship fields of a custom object
GET https://{tenant}.atomicwork.com/api/v1/custom-objects/by-id/{id}/relationships
Returns the same CustomObjectDetailsDto shape as getCustomObject, but
customData is restricted to relationship reference keys only — scalar,
dropdown, date, and other non-relationship fields are omitted. Each
objectType.sections[*].fieldIds list is filtered to retain only the
field IDs that correspond to relationship field definitions; empty
sections are preserved so the UI gets a stable section layout.
Useful when a caller needs to display a CO's links to other entities without paying the cost of resolving the full custom_data payload.
