Domain Registration

Domains can be registered in Real-Time with the API AddDomain command.

command = AddDomain
domain  = (DOMAIN)

REQUIRED

ownercontact0 = (CONTACT)
admincontact0 = (CONTACT)
techcontact0 = (CONTACT)
billingcontact0 = (CONTACT)
nameserver0 = (NAMESERVER)
nameserver1 = (NAMESERVER)

OPTIONAL

auth = <TEXT> | <NULL>
transferlock = 0 | 1 | <NULL>
subuser = <TEXT> | <NULL>

Domain Transfer

The transfer has to be initiated by the gaining registrar and can be requested with the API TransferDomain command.
A valid Authorization Code must be provided to initiate a transfer successfully. You may obtain the authorization code from the losing registrar.
Domain transfers are processed in Real-Time.

command = TransferDomain
domain = (DOMAIN)

REQUIRED

action = REQUEST | APPROVE | DENY | CANCEL | USERTRANSFER
auth = <TEXT>

OPTIONAL

order = CREATE | REPLACE | UPDATE

subuser = <TEXT> | <NULL>
period = <PERIOD>
transferlock = 0 | 1 | <NULL>

Delete Domain

Domains can be deleted with the API DeleteDomain command.
There is a Deletion Restorable Period of 40 days.

command = DeleteDomain
domain = (DOMAIN)

REQUIRED

n/a

Restore Domain

Restores can be processed in realtime. A restore is possible within 40 days upon deletion. Please use the command RestoreDomain.

command = RestoreDomain
domain = (DOMAIN)

REQUIRED

n/a

OPTIONAL

renewalmode = <NULL> | <TEXT>
subuser = <TEXT>

Ownerchange

All contact information with the exception of registrant Name, Firstname and Organisation can be updated through the ModifyDomain command.
In order to change the owner you have to request a trade with the TradeDomain command. This can be done through our web interface or through our API:

command = TradeDomain
domain = <DOMAIN>
ownercontact0 = <CONTACT>

The trade request will be processed in Real-Time by the registry.

A Change of Registrar with the simultaneous change in the Registrant is not possible. Please be aware that domain name must be already managed by us. If the domain is currently managed by another registrar there are two possibilities:
   1.) first step: transfer the domain to us, second step: trade the domain with us.
   2.) first step: trade the domain with the current registrar, second step: transfer the domain to us.

There are no specific parameters available

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.
