Nominet EPP API is released and maintained by 1stDNS Limited and is designed for developers/tag holders to be able to intergrate with the Nominet EPP using PHP.
Other language versions may become availiable as the need presents itself for us to develop these.
Find the Nominet EPP Files and Documentation (Coming soon, although the code is reasonably self explanatory) here.
Any bugs you find or any additional features you would like to be added please contact us or use the bug tracker on sourceforge here.
