 # Admin API
 
+The admin http API does not currently work with an api token. Api Token's are currently only linked to an organization and organization role. They cannot given
+the permission of server admin, only user's can be given that permission. So in order to use these API calls you will have to use basic auth and Grafana user
+with Grafana admin permission.
