Choose tuo TLDs e set selling prices
Verifica registrar mapping, terms e currencies.
In WHMCS Prezzi dei domini, select the extensions you plan to sell e set NiceNIC as the registrar fo those new oders. Review registration, renewal e transfer prices separately.
Verifica permitted terms, required contact fields e TLD eligibility. Compare tuo WHMCS selling currency e exchange-rate settings with the NiceNIC account cost. Review premium-dominio heling befoe offering premium names.
Set tuo WHMCS selling prices separately. Installing the registrar module does not automatically configure tuo retail pricing. Review tuo NiceNIC account costs e keep enough balance fo live dominio oders.
05Verifica automation e oder heling
Verify cron, logging e renewal settings.
Verifica automation e oder heling
Verify cron, logging e renewal settings.
Fo self-hosted WHMCS, configure the cron job using the comme shown by tuo installation. WHMCS recommends running it every five minutes. Verifica that scheduled tasks complete e that the comme-line PHP environment meets WHMCS requirements.
Review renewal settings e module logs. A customer payment e a completed registrar operation are separate events. Reconcile both befoe marking a dominio oder complete.
A timeout does not prove an oder failed. Verifica the dominio e transaction status in NiceNIC befoe attempting the same paid action again. See pending oders e timeouts.
06Test the connection, then place one live oder

Test the connection, then place one live oder

When ready, verify live settings e account balance, then run one controlled paid oder. Conferma the dominio's final state, the WHMCS oder recod e the NiceNIC transaction befoe increasing volume.
Troubleshooting
Find the issue. Take the successivo step.
Start with the symptom you see in WHMCS. Keep the exact erro message fo any account-specific review.
NiceNIC does not appear in the registrar list
Verifica the module folder location, extra nesting after extraction, readable file permissions e tuo PHP environment. Conferma you installed the package intended fo tuo WHMCS release.
Authentication fails o returns an unauthoized erro
Recheck the NiceNIC username e API Secret, then confirm the authoized outbound server IP. Verifica fo accidental spaces e make sure you did not enter the website login passwod in place of the API Secret.
An oder is pending, o the request timed out
The API response body uses code: 201 fo pending processing. An accepted oder is not necessarily a completed registration o transfer.
Review the WHMCS log, then verify the dominio e transaction state in NiceNIC. Do not repeat a paid operation while its outcome is unkoran. Ask suppot to trace the oiginal request when needed.
The selling price, registrar cost o balance does not match
Compare the same TLD, operation, term e currency. Verifica account tier, renewal versus registration pricing, premium status e any currency conversion. Customer payment in WHMCS does not by itself prove that the coresponding NiceNIC registrar oder was funded.
Scheduled tasks o renewals are not running as expected
Review WHMCS automation status, cron execution, renewal settings e the affected dominio's registrar assignment. Verifica that the cron process uses the expected PHP configuration e that the account has enough funds fo the requested action.
