API commands

Please find in the following a set of the most commonly used standard API commands in order to register, modify, renew, and transfer a domain name.

Domain Registration

(API Command reference » AddDomain)
command         = AddDomain
domain          = yourdomain.lu
period          = (INT)
ownercontact0   = (CONTACT)
admincontact0   = (CONTACT)
techcontact0    = (CONTACT)
billingcontact0 = (CONTACT)
nameserver0	= (NAMESERVER)
nameserver1 	= (NAMESERVER)

If the used name servers are not correctly configured, the AddDomain command will fail since the registry performs a DNS pre-check.

Domain Modification

(API Command reference » ModifyDomain)
Standard command
command = ModifyDomain
domain  = yourdomain.lu


command       = TradeDomain
domain        = yourdomain.lu
ownercontact0 = (CONTACT)

A change of the registrant for a .LU domain can be done through the webinterface or API. A trade is not free of charge. The domain will be renewed and the registration period starts from beginning. After the trade has been started the admin contact will receive a confirmation mail which he has to approve. A failed request for a change of registrant will be charged with a special fee.

Domain Renewal

(API Command reference » RenewDomain)

As .lu domains can not be renewed explicitly. To renew a .lu domain you have to set the domain renewal mode or default renewal mode to "AUTORENEW" or "RENEWONCE".

Domain Deletion

(API Command reference » DeleteDomain)
COMMAND = DeleteDomain
DOMAIN = yourdomain.lu

Domain Transfer

(API Command reference » TransferDomain)

Transfer procedure

command = TransferDomain
domain  = yourdomain.lu
action  = request


nameserver0 = ...
nameserver1 = ...

After the transfer has been started the admin contact will receive a confirmation mail which he has to approve. A failed request for a domain transfer will be charged with a special fee. We recommend to add two nameservers within the TransferDomain command. The transfer will be processed as soon as it has been confirmed by the admin of the domain name.

Domain Restore

(API Command reference » RestoreDomain)
command = RestoreDomain
domain  = yourdomain.lu

Domain Restrictions

Pre-configured nameservers are required. See here for zonecheck.

Supported IDN Scripts

The following IDN scripts are supported by .lu.
Provide the LANGUAGE TAG corresponding to your desired IDN within the AddDomain command as X-IDN-LANGUAGE extension.
