API

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 losing registrar has to inititate the transfer to push the domain to the gaining (new) registrar. The gaining registrar has to be aware of the planned domain transfer. Hence the transfer has to be requested with the API TransferDomain command.

command = TransferDomain
domain = (DOMAIN)

REQUIRED

action = REQUEST | APPROVE | DENY | CANCEL | USERTRANSFER

OPTIONAL

order = CREATE | REPLACE | UPDATE
period = <PERIOD>
transferlock = 0 | 1 | <NULL>
subuser = <TEXT> | <NULL>

Delete Domain

Domains can be deleted with the API DeleteDomain command.
There is no Deletion Restorable Period and no Deletion Hold Period. Deleted domain names will be available for new registrations immediately.

command = DeleteDomain
domain = (DOMAIN)

Restore Domain

Restores are not possible.

command = RestoreDomain
domain = (DOMAIN)

OPTIONAL

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

Ownerchange

An Ownerchange is free of charge and can be done with the API ModifyDomain command.

PLEASE NOTE: The registry does not support contact handle updates directly. To update a domain's contact information, a new contact handle with the updated information must be created first. Then using this new contact handle and the ModifyDomain command, the domain's contact information can be changed.
