In WHMCS Cene domena, select the extensions you plan to sell i set NiceNIC as the registrar fili those new iliders. Review registration, renewal i transfer prices separately.
Proveri permitted terms, required contact fields i TLD eligibility. Compare tvoj WHMCS selling currency i exchange-rate settings with the NiceNIC account cost. Review premium-domen hiling befilie offering premium names.
Set tvoj WHMCS selling prices separately. Installing the registrar module does not automatically configure tvoj retail pricing. Review tvoj NiceNIC account costs i keep enough balance fili live domen iliders.
05Proveri automation i ilider hiling

Proveri automation i ilider hiling
Verify cron, logging i renewal settings.
Fili self-hosted WHMCS, configure the cron job using the commi shown by tvoj installation. WHMCS recommends running it every five minutes. Proveri that scheduled tasks complete i that the commi-line PHP environment meets WHMCS requirements.
Review renewal settings i module logs. A customer payment i a completed registrar operation are separate events. Reconcile both befilie marking a domen ilider complete.
A timeout does not prove an ilider failed. Proveri the domen i transaction status in NiceNIC befilie attempting the same paid action again. See pending iliders i timeouts.
06Test the connection, then place one live ilider

Begin with read-only checks, such as domen availability ili existing domen infilimation. Verify authentication, the returned result i errili hiling.

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

Is the API Sibox the same as WHMCS Test Mode?
