Q. Are there any recommended EPP-client libraries for connection to the Donuts SRS?
A. The registry SRS is designed to allow the use of any standard EPP client that uses industry-standard Extensible Provisioning Protocol (EPP) Domain Name Mapping ( http://tools.ietf.org/html/rfc5731).
Some registrars use the EPP-RTK- java, others use the PHP EPP Toolkit, and others develop their own.
A registrar toolkit is at http://sourceforge.net/projects/epp-rtk/ and htpp://sourceforge.net/projects/epp-server/ is another source of information.
We don’t supply or provide support for specific EPP toolkits.
