“Claims Check Form” is the only launch phase extension (http://tools.ietf.org/html/draft-tan-epp-launchphase-12) implemented in SRS.
Perform an EPP check command with phase launch extension for claims.
The Early Access Program Registrar Integration Guide document has the formal syntax and detailed explanation of its use with the EPP protocol.
Please contact Donuts Tech Support department if you have any further questions.
Please note that EAP and Premium Names use the same EPP extension and the schema is included in the Donuts “Price Categories Guide” which is also available via the Document section of the Registrar web portal
