When working with the UIMAPI to query regarding alarms (http://<hostname>/uimapi/alarms), requests can be sent for alarms that are not assigned using the following payload:
{
"assigned_to": null
}
However, the results of this API request returns all alarms, assigned and unassigned.
UIM 23.4 CU3 and earlier
As of UIM 23.4 CU3, this functionality is not currently supported.
