We have build our own custom DNS system, and need cPanel to interact with it.
Our custom DNS system have a documented PHP API.
cPanel provides the following and maybe more documentation for their dnsadmin module:
[login to view URL]
[login to view URL]
The expected functionality is, that cPanel DNS actions are synchronized to our system through the API.
This should be do-able for $50 USD if you are skilled enough.
