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.
As soon as a domain transfer has been initiated it can either be approved ("ACK") by Registrar or denied ("NACK") by Registrar. If the registry receives neither a denial ("NACK") nor an approval ("ACK") the transfer will be ACKed after 3 days.

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 60 days.

command = DeleteDomain
domain = (DOMAIN)

REQUIRED

n/a

Restore Domain

Restores can be processed manually within 60 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.

Please note that the registry does not support handle updates. You have to create a new handle containing the same information for Name, Firstname and Organisation as well as the updated contact information and attach it to the domain with 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>

You have to state the contact handle of the new registrant. Please remember that the registry does not allow handle updates. Please do always create a new contact handle and do not use modified contact handles.

Before a trade gets processed by the registry, a confirmation is required: A fax form is required by the registry to process a trade. Once confirmed then the trade will be processed.

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, please execute the RestoreDomain command. Please note that the restore will be handled manually and the domain will not be available in real-time.
