 Registering a user requires specifying the group to which the user will belong. There are 2 built-in groups, with groupName of 'Administrators' or 'Users' and corresponding groupId of 1 and 2 respectively. Available groups can be retrieved via the `/api/admin/groups/list`
 
 This operation can only be performed by a user that is a member of a group with the admin flag enabled, or a user who has the admin flag enabled individually on their database record.
