NiceNIC Domain Registrar Module for WHMCS

NiceNIC Domain Registrar Module for WHMCS

Developed By NiceNIC Group

Compatible with WHMCS v9.0

Connect your WHMCS installation to NiceNIC and manage domain orders through the NiceNIC Domain API. Built for hosting providers and domain resellers, this official NiceNIC module brings domain registration, renewal, transfer and management into your existing WHMCS workflow.

NiceNIC is an ICANN-accredited domain registrar (IANA ID: 3765), operating since 2006. We offer 2,500+ domain extensions, free WHOIS privacy for eligible TLDs, and domain prices that include applicable ICANN fees.

Domain registration and management

  • Check domain availability.
  • Register new domains and renew existing domains.
  • Submit incoming domain transfers.
  • Retrieve domain information.
  • Update nameservers and domain contact details.
  • Manage domain locking and retrieve EPP transfer codes where supported.
  • Use error logging to help troubleshoot failed operations.
  • Enable Test Mode when preparing your integration.

Available operations and registration requirements vary by TLD.

Free Domain API access

Domain API access is available to both Market Accounts and Reseller Accounts at no additional API access charge. Domain transactions are billed at the prices assigned to your account.

NiceNIC also provides an API Sandbox for testing authentication, requests and response handling before production use.

Getting started

  1. Download and extract the module package.
  2. Upload the module files to your WHMCS installation under modules/registrars/nicenic/.
  3. Open Domain Registrars in your WHMCS administration area and activate NiceNIC.
  4. Enter your NiceNIC username and API Secret, then configure Test Mode for testing.
  5. Configure your TLD pricing and select NiceNIC as the registrar for the extensions you want to sell.

Use a module release compatible with your WHMCS and PHP versions. PHP cURL, HTTPS connectivity and valid NiceNIC API credentials are required. Verify your configuration before enabling live orders.

Fund your NiceNIC account with crypto

Fund your NiceNIC balance with USDT, BTC, ETH, USDC and other supported payment options, then use available credit for eligible domain operations through WHMCS.

NiceNIC charges a 0% crypto processing fee. The online payment provider currently charges a 1.5% service fee; wallet or network fees may also apply.
