   You add a space to an isolation segment by sending a request to the endpoint for the space, setting its `isolation_segment_guid` data property to the GUID of the new default isolation segment. For example:

The isolation segments you can see information for depends on your role, as follows:
  
  * **Admins** see all isolation segments in the system.
  * **Org Managers** see isolation segments containing orgs that they belong to.
  * **Other users** see isolation segments containing spaces that they belong to.
