Adding Remote Database Access Hosts

My application need to synchronize a local mysql database with one on the server. So I need to add Remote Database Access Host on my cpanel. It is having dynamic IP. I need some method to add the IPs automatically to Remote Database Access Hosts once a user login to the application.

I know there is a API available is it possible to do this with API> I am not so familiar with API implementation. So can i get a PHP implementation of this api call.

Thank you
