General API Information

The Rackspace Cloud DNS API is implemented using a RESTful web service interface. Like other Rackspace Cloud services, this service shares a common token-based authentication system that allows seamless access between products and services.


All requests to authenticate and operate the service are performed using HTTPS on TCP port 443. For authentication instructions, see [Authenticate to the Rackspace Cloud](/reference/Authenticate to the Rackspace Cloud).
