Required permission: VariableCreateDeleteGroup

To delete a group, send a DELETE request to the ID of the variable group. For example, DELETE http://my_server:3580/nivariable/VariableValueGroups('1587dcd4a87d118ae3ddd0fce09246f6')

If the DELETE request succeeds, a 204 status code is returned with an empty response body. If the DELETE request fails, the OData error object detailing the error is returned in the requested format (XML or JSON).
