There are no specific parameters available

The following overview shows you all available Domain Addons which can be used for this special kind of TLD. It also shows the respective API parameters which are required to activate the Domain Addons:

Addon Class	Parameter to (de)activate *1)	Renewal term *2)	Affected Parameters *3)
Trustee	X-CN-ACCEPT-TRUSTEE-TAC = 0 | 1	1 year	OWNERCONTACT

*1) Parameter to (de)activate: When accessing our backend through the API, you can either activate the addon with X-CN-ACCEPT-TRUSTEE-TAC=1 or deactivate it with
      X-CN-ACCEPT-TRUSTEE-TAC=0

*2) Renewal Term: Is the minimum renewal term of the "Addon Class"

*3) If you are using a "Trustee" Domain Addon normally the original owner contact or the original admin contact or both are replaced by a contact provided by the trustee provider.
      

Restore Process

To restore a domain as a RegistrarOC customer, you simply have to execute the RestoreDomain command. HEXONET directly forwards the restore request to the registry, which performs the restore in real-time. As soon as the restore is complete, the domain will get assigned to your account with the original domain data.

Please do not initiate a restore directly at the registry (e.g. using the registrar webinterface). All restore operations must be performed through our system.
