# Creates a static unique custom group with exclusive resource membership

Creates a static unique custom group (groupCategory=5) with explicit member resources. Only computer-type static unique groups are supported — user-type static unique groups are not allowed. Static Unique groups are used for Scope of Management — they enforce that each resource belongs to only ONE static unique group of the same type, enabling non-overlapping technician territories. Unlike regular Static groups where a resource can belong to multiple groups, Static Unique groups reject any resource already in another Static Unique group.

Required: `groupName`, `groupType=1`, `groupCategory=5`, `resourceIds`.

Prerequisites: Call [Get Available Resources](https://www.manageengine.com/products/desktop-central/custom-groups-get-available-resources.html) to discover valid resource IDs.
