Test Mode

ResellerClub requires the use of a Demo Account Reseller ID and API Key with the Test URL instead of your Live Account credentials. Use of your Live Account credentials, even with the Test URL, will cause you to perform actions in the live environment.

You can use test mode to simulate domain registration and management function without registering a domain or incurring charges. This can be useful to test WHMCS configurations.


Live nameservers will return a Nameserver is not a valid Nameserver error unless you create and register them in the demo environment before attempting domain registrations on the demo platform. The demo control panel will try to check the validity of the nameservers in the demo platform and not on the registry.

You can use and as your nameservers without registering them on the demo environment.

Terms and Conditions

ResellerClub requires that clients agree to their terms and conditions when registering a domain. To do this, it adds an additional checkbox to the registration process.

To translate the checkbox name, use tnc as the LangVar key in the appropriate language file in the lang/overrides/ directory:

$_LANG['tnc'] = 'I agree to the ResellerClub terms and conditions.';
For more information, see Additional Domain Fields.

Domain Contacts

Domain registration creates a unique contact for each domain. This contact becomes the Registrant, Billing, Tech, and Admin contact for the domain’s Whois records. Modifying the Whois details for the domain will change only that domain.

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 Domain Pricing.

Automatic Domain Synchronization

This module supports automatic domain synchronization for syncing expiry dates and status changes for incoming transfers.

To use this, enable Domain Sync Enabled and configure the domain sync task at Configuration () > System Settings > Automation Settings.

Check Prices

You can check the prices that you pay for each domain from within your ResellerClub account.

To do this:

  1. Log in to the ResellerClub control panel.
  2. Go to Settings > Manage Products and Pricing > Set the price for the TLDs you want to sell.
  3. Select the Sub-Reseller tab.
  4. Click Manage Pricing for the TLD that you want to view.

A Your Cost Price row will display the price for each type of that TLD.
