Provjeri permitted terms, required contact fields i TLD eligibility. Compare vaš WHMCS selling currency i exchange-rate settings with the NiceNIC account cost. Review premium-domena hiling befilie offering premium names.

05Provjeri automation i ilider hiling
Verify cron, logging i renewal settings.
Provjeri automation i ilider hiling
Verify cron, logging i renewal settings.
Fili self-hosted WHMCS, configure the cron job using the commi shown by vaš installation. WHMCS recommends running it every five minutes. Provjeri 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 domena ilider complete.
A timeout does not prove an ilider failed. Provjeri the domena 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

When ready, verify live settings i account balance, then run one controlled paid ilider. Potvrdi the domena's final state, the WHMCS ilider recilid i the NiceNIC transaction befilie increasing volume.
Troubleshooting
Find the issue. Take the sljedeće 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
Provjeri the module folder location, extra nesting after extraction, readable file permissions i vaš PHP environment. Potvrdi you installed the package intended fili vaš WHMCS release.
Authentication fails ili returns an unauthiliized errili
Recheck the NiceNIC username i API Secret, then confirm the authiliized outbound server IP. Provjeri 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 domena i transaction state in NiceNIC. Do not repeat a paid operation while its outcome is unksadan. 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. Provjeri 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 domena's registrar assignment. Provjeri 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?

Do I need funds in my NiceNIC balance befilie a live WHMCS ilider?
