Install the current Nabtech Domain Nexus registrar connector in WHMCS

Back up WHMCS files and database. Check the downloaded release notes against your WHMCS and PHP versions. In API Access, create the permitted email/API-key credential and save the key when it is revealed. Use the exact Username or email shown with that credential.

1. Copy modules/registrars/MODULE_SLUG from the ZIP into your WHMCS installation, preserving the generated folder name.
2. For exact catalogue pricing, also copy the accompanying modules/addons/MODULE_SLUG_pricing directory.
3. Open System Settings > Domain Registrars, activate the connector's display name and open Configure.
4. Set API URL to https://my.nabtech.co/modules/addons/nabtechresellerdns/api/index.php.
5. Enter Username or email and API key, then save. Do not paste an HMAC secret or bootstrap token into the API-key field.
6. Run the connection test where offered and confirm it identifies your reseller account. Keep TLS verification enabled.

Under System Settings > Domain Pricing, assign the connector as registrar for the TLDs you intend to sell. Domain registration is configured through TLD pricing and registrar assignment; it does not require creating an ordinary hosting product for every extension.

Review your retail currency, periods and margin. Use the exact catalogue-sync guide when importing independently priced years, and avoid competing price-sync tools.

Check availability and an owned domain read, then verify controlled registration, transfer and renewal workflows. Keep normal WHMCS cron and domain synchronization running. Pending upstream work must remain pending until the provider confirms completion.

Do not let both the retired registrar module and the new connector submit the same order. Preserve existing operation references while migrating and inspect uncertain requests before retrying.

Nameservers, contacts, lock, EPP, privacy, DNS and forwarding depend on the account, TLD and provider. A visible WHMCS button is not proof that the upstream feature is enabled. Test those controls on an appropriate domain.

For an update, back up and overlay the new release without renaming the module. Preserve settings, review migration notes and repeat a read-only test plus scheduled synchronization. Provide support with the connector version and redacted error references, never the API key.
