To activate and begin using the HEXONET registrar module, follow the steps below:

  1. Log in to the WHMCS Admin Area.
  2. Go to Configuration () > System Settings > Domain Registrars or, prior to WHMCS 8.0, Setup > Products/Services > Domain Registrars.
  3. Click Activate for HEXONET.
  4. Enter your HEXONET account username and password.
  5. Click Save Changes.

Auto Renewal
Configure the default domain renewal mode to AUTOEXPIRE in your HEXONET Control Panel, otherwise domains might be renewed without being paid by the customer in WHMCS

Renewal Mode Setting
  1. Log in to the HEXONET control panel.
  2. Go to Products > Domain Name Settings. Click + More and search for it if you do not see it in the list.
  3. For Renewal Mode For New Domains, select Expire Domain.
  4. Click Save.

IP Registration

HEXONET's API is not IP address-restricted by default. However, you can configure this restriction in the control panel to improve security.

To do this:

  1. Log in to HEXONET.
  2. Click on your username in the upper-right corner.
  3. Navigate to Settings > Security > IP Restrictions.
  4. Enter your server's IP address.
  5. Click Save Changes.

You can find the IP address to whitelist at Help > License Information in the WHMCS Admin Area.

Test Mode

The HEXONET's OT&E (Operational Test & Evaluation) system permits testing of domain registration and management actions without actually registering domains so no charges are incurred.

To use it:

  1. Create an test account here.
  2. In WHMCS, enter your HEXONET test account username and password.
  3. Check TestMode.
  4. Save Changes.

To return to live mode, enter your live HEXONET username and password at Configuration () > System Settings > Domain Registrars or, prior to WHMCS 8.0, Setup > Products/Services > Domain Registrars. Then, uncheck TestMode.


Optionally, you can enter the URL of your proxy server. For more information, [see HEXONET's documentation.

IDN Configuration

By default, the HEXONET API converts domains to IDN format (recommended). Change this to PHP to make use of the idn_to_ascii function (deprecated). This function [must be compiled] in your php.ini file.


Enable this to display the DNSSEC configuration interface in the Client Area domain details page. This feature allows your customer to add DS and KEY records and set the maxSigLife setting.


Enable to automatically apply the transfer lock to new domain registrations.

Automatic Registration

WHMCS allows you to set up automatic domain registration on a per-extension basis, enabling you to use different registrars for different TLDs.

To enable automatic registration, see Configuring Automatic Registration

Automatic Domain Synchronization

The HEXONET module supports automatic domain synchronization for syncing of expiry dates and status changes for incoming transfers.

To enable this functionality:

  • Enable Domain Sync Enabled in Configuration () > System Settings > General Settings > Domains or, prior to WHMCS 8.0, Setup > General Settings > Domains.
  • Configure Domain Sync Cron on your system.


Disconnected / Authorization Failed

Common causes for a Disconnected or Authorization Failed error are:

  • An incorrect password or username in the registrar module settings at Configuration () > System Settings > Domain Registrars or, prior to WHMCS 8.0, Setup > Products/Services > Domain Registrars.
  • Two-Factor authentication is enabled for the user in your HEXONET account. This can be resolved by deactivating it for your HEXONET user or creating a restricted user role and new user that WHMCS will use to connect to HEXONET's API.
  • IP address restriction settings in your HEXONET account do not allow your WHMCS server to connect to the HEXONET API.
  • Your server firewall is blocking the connection.
  • You are connecting to the test environment using your HEXONET production account or vice versa. The HEXONET OTE API uses a different set of login credentials than the production environment.

Empty response from API

This can occur when the API endpoint is unreachable. You can test this by running the ping api.ispapi.net command from the WHMCS server's command line.

The module uses ports 80 and 443 to connect to HEXONET over HTTP. Make sure that these ports are whitelisted in your server firewall.
