Installation and Configuration

In this section we will show you how to properly install and configure your InterNetX Domain Plugin for WHMCS.

1. Download the WHMCS Domain Plugin in the WHMCS Marketplace or here on our Help Center page.

2. Unpack the zip-file and upload the files to your server into your root WHMCS directory.

3. Duplicate dist.additionalfields.php file located at the /resources/domains/ directory to additionalfields.php and add code below at the end of the file:

 * This file will load proper additional parameters for InterNetX registrar domain module
$filename = ROOTDIR . DIRECTORY_SEPARATOR . 'resources' . DIRECTORY_SEPARATOR . 'domains' . DIRECTORY_SEPARATOR .'InterNetX_additionaldomainfields.php';
if (file_exists($filename)) {
} else {
    die('Can not load InterNetX_additionaldomainfields.php File error: resources/domains/dist.additionalfields.php');

(This will add domain extensions for the domain plugin and will overwrite some of the standard WHMCS extensions that are not required.)

4. Now, you have to set up your contact details. At the Setup > General Settings > Domains. Uncheck "Use Clients Details" checkbox, fill contact details and press Save Changes.

5. In order to proceed, go to the Setup > Product/Services > Domain Registrars, find InterNetX and press Activate next to it.

6. Now, enter your API access details, API URL and default nameservers.

          (if you are using virtual nameservers from InterNetX please update /modules/registars/InterNetX/classes/class.InternetX_API.php and change the two "" entries  to your own virtual nameserver domain)

  • Context: The default context for AutoDNS is 4. If you are using Personal AutoDNS please use your exclusive URL and the context number you have received.
  • Reply To: Defines where the replies of the AutoDNS orders will be sent by email. These emails are required to track orders with errors. You can select from the email addresses of your administrator accounts.
  • MX Record: Here you can set the default subdomain name for the MX Record. The MX will point to the same IP that is set in "IP Address". We suggest to use the name webmail .
  • IP Address:  The IP address where the DNS Records that are created during domain registration will point. The IP also defines the MX Record subdomain name supplied above.
  • Auto Delete: Do not activate this option unless you are instructed to do so! Else the feature will result in double renewals and costs for domains!
  • Admin Contact: The OwnerC will also be AdminC in the public Whois. Else the Client will only be OwnerC.

→ Afterwards, press Save Changes button.

It is also possible to use the AutoDNS Demo System for testing and implementation, if you need access to the AutoDNS Demo System (Sandbox) please contact The sandbox nameservers are ns1/
To use the AutoDNS Demo System please activate "Test Mode".

Congratulations! You have just finished the initial installation and configuration of the module.


TLD Management

Next to basic actions

Admin area

The InterNetX Domain Plugin for WHMCS allows you to perform various actions on your client’s domains.

In addition to basic actions (Register, Transfer, Renew and Modify Contact Details) you are able to carry out functions such as Get EEP Authinfo Code, Request Delete, Transfer OUT ACK and Transfer Out NACK.

Important Note:

If you want to do a manual synchronisation of your domains and their expiry/due dates you can start the Cron Sync manually:

Client area

Your client can manage all relevant aspects of their domain. In this section we will show the available features. On the domain’s details page your client can view basic details of his domain and order it's renewal.

In the Auto Renew tab you are able to enable/disable the Auto Renew functionality.

Important Note:

Disabling Auto Renew will result in an automated deletion of the domain on the expiration date! If you reactivate Auto Renew the delete order will be removed again.

You can also change the domain’s nameservers, this can be done in the Nameservers tab. 

At the Addons tab you can manage addons ordered along with a domain.

In the Addons tab you can manage addons ordered along with a domain.

  • ID Protection allows you to activate and deactivate the Whois Privacy Service.
  • DNS Host Record Management allows you to manage the DNS Entries for the domain.
  • Email Forwarding allows you to redirect email addresses to other external email addresses.

The InterNetX Domain Plugin for WHMCS also allows you to modify the whois contact details. The only limitation here is you cannot change the first and last name.

SchlundTech allows you to set up email forwarding if you have.

DNS Management addon enables you to manage the DNS records of your domain.

InterNetX allows to set up email forwarding if you have ordered the InterNetX Redirector service. Please contact to get the Redirector service activated.

Important Note:

To activate email forwarding the MX record of the domain must be set to a hostname that points to IP address in the DNS entry!

You can easily receive your domain’s EPP Authinfo Code, simply go to the Management Tool > Get EPP Code.

Additionally, you can easily set up domain forwarding. Go to Management Tools > Manage Domain Forwarding:
InterNetX allows to set up domain forwarding if you have ordered the InterNetX Redirector service. Please contact to get the Redirector service activated.

Important Note:

The Domain/Subdomain Forwarding requires a change of the A-Record in the DNS entry. Please set the A-Record for the domain/subdomain to the IP Address in order to get Domain Forwarding activated.

You can also change the domain owner.


The InterNetX WhoisProxy acts as a singular intermediatery which accesses the various whois servers of the registries, thereby saving users the effort of sending whois queries to every whois server.

Whoisproxy integration into WHMCS

How to change the Whois Server in WHMCS:

Example TLD List

Important Note:

The list of available TLDs will change from time to time especially with new gTLDs being introduced nearly every week!

The whois server list is located at: /resources/domains/whois.json

You can edit the whois file according to your needs and overwrite the regular WHMCS whois configuration per TLD.

Example list of TLDs and Whois Servers:

     "extensions": ".com,.net,.org,.de,.cat,.ca,.travel",
     "uri": "socket://",
     "available": "free"
     "extensions": ".bike",
     "uri": "socket://",
     "available": "free"
     "extensions": ".at",
     "uri": "socket://",
     "available": "free"

A complete list of all available WhoisProxy TLDs can be retrieved using the following command:
whois -h tld

Premium Domains

Additional Feature For InterNetX WHMCS Domain Registrar: Premium Domains

The Premium Domains module adds premium domain functionality inside the existing InterNetX WHMCS Domain Registrar module.

Important Note:

The premium domain feature requires using the WhoisProxy!

To use the premium domain function, our WhoisProxy is mandatory.

If the lookup provider is changed, all Whois Queries including non premium Domains, will be executed via the WhoisProxy.

Please contact our Sales Team( to receive access to the WhoisProxy.

Installation instructions

  • Go to Admin Area of your WHMCS.
  • Go to Setup > Addon Modules and activate "InterNetX Premium Domains Addon".
  • There is no need to configure the addon, just click "Activate" button.
  • Go to Setup > Products/Services > Domain Pricing, and change your Lookup Provider to "InterNetX" by clicking on "Change" button in "Lookup Provider" section:

Then select "InterNetX" from all lookup providers list:

Please make sure that the premium domain button is set to "ON":

window to allow user enter


The Premium Domains module allows the user to set his own price for each premium domain class. To do this you have to:
Click "Configure" button in the premium domains section:

The module will change the "Configure Premium Domains Levels" window to allow the user to enter and save their premium domains classes.
Enter premium domain class names inside text fields and save them into database by clicking "Save" button:

Premium domian classes can also be deleted from the database by clicking on "Delete" button:

After adding a premium domain class to the database, the user has the possibility to configure it's pricing by clicking on the "Configure" button:

In the next window the user can set the RegisterTransfer, and Renewal prices for selected price class, and save it into the database by clicking the "Save" button:

From now on if a premium domain will be detected by the WHMCS Domain Registrar the price will be taken from the database and set in the "Client Area" during the domain registration process.


In "Configure Premium Domain Pricing" the user can only configure pricing for a one year period, because WHMCS does not allow users to register premium domains for longer than one year.

In this same window only one currency is available because WHMCS and the Premium Domains module automatically recalculates prices to other currencies based on the current currency rate.

When a user wants to disable register/renew/transfer prices of domain just type "0" (zero) in the appropriate premium domain pricing field.

Important note about renew prices:

When you are in the "Client Area" and go to: Domains > My Domains and click "Renew" button on the left, the action bar displaying the renew prices of premium domains will not change. WHMCS does not support changing prices in this place.

Additional information about Custom Client Area Forms and Custom Localistation:

Custom Forms in Client Area

  • Email Forwarding → /modules/registrars/InterNetX/domainForwarding.tpl
  • Domain Redirect → /modules/registrars/InterNetX/domainForwarding.tpl
  • Owner Change → /modules/registrars/InterNetX/changeOwner.tpl

Changes to Design and Localisation can be done here, but Localisation should be done by using Language Tags.

Custom Localisation via Language Tags

Your will find language Tags all over WHMCS, we are using separated "internetx" Language Tags to make it visible who made the localisation






Language Tags beginning with "$LANG.internetx" are located in



These individual Language Tags can be changed as needed.

Other Language Tags like "$LANG.clientareacancel" without the "internetx" are WHMCS Language Tags.

They can also be overwritten by inserting $LANG.clientareacancel in /lang/overrides/xxxxx.php

e.g. if you do not like the Button "Cancel" in your Client Area forms, because the button does not cancel but does undo, you simply can override $LANG.clientareacancel from "Cancel" to "Undo Changes" in /lang/overrides/english.php

Localisation of Domain Extensions

Some TLDs require additional data, e.g. a VAT Number or a Passport number.

These Extensions are managed in a separate file and are not translated on purpose:


If you want to translate these extension names you can either create own Language Tags or change it directly in InterNetX_additionaldomainfields.php if you are only offering one single language for your customers.


$additionaldomainfields[".ru"][] = array("Name" => "ID Card Number".......

After the initial " array("Name" => " is the localisation, you can change "ID Card Number" to "ID Number" as you like it.
