10.1.5 vCloud Director API for NSX
vCloud Director 8.20 provides a new API for advanced networking services that is a multitenant-safe proxy API to the underlying platform NSX APIs.
Tenancy concept, authentication and authorization is provided with existing vCloud API through which a valid session token must be acquired
Authenticated calls to the NSX Proxy API provide direct access to the networking objects of the particular tenant (Org VDC Edge Gateways and Org VDC Distributed firewall) using vCloud Director UUID identifiers.
The following URI paths are currently available:
/network/edges/.*
/network/firewall/.*
