We have put together a REST API so customers can dynamically update their DNS. Please note that this tool is part of our Labs and our technical support department cannot provide assistance with it. Labs services are supported through our public forum at forums.sonic.net.

Since this is a labs project please direct any questions to the forum as support will not be able to assist you.
We do have some example code hosted at GitHub here:
