1. Open Domain Nexus Servers, add a connection and choose cPanel / WHM.
2. To reuse a WHMCS server, select it in WHMCS cPanel server. Confirm its address and account refer to the intended machine. The module can use its stored connection details.
3. For a dedicated connection, enter Hostname or IP address, WHM username and API token or password. Prefer a separately revocable WHM API token with the necessary DNS privileges.
4. Review Default IP for new zones. An omitted value can use the linked server's address, so confirm it is suitable for the initial zone.
5. Leave cPanel Account Username empty unless you intend to park DNS-only domains as aliases under an existing cPanel account.
6. Save and check the connection, then test an owned zone read and temporary TXT change.

A connection that reads zones may still lack privileges to add records, create zones, manage DNSSEC or create a parked alias. Prepare the WHM token against cPanel's current API privilege reference and the operations you will enable. For a reseller, confirm the target zone belongs to that reseller's permitted scope.

Enter the existing cPanel account username, not its primary domain or the WHM login name. It is an optional DNS parking target. The dedicated parking guide explains how eligible DNS-only domains become aliases while hosted domains and ownership conflicts remain protected.

Explicit connection values can override details supplied by the linked WHMCS server. Review a stale typed host, username or secret before assuming the WHMCS server record is wrong. Keep the linked server association accurate when using automatic hosting handoff, and test the DNS and hosting workflows separately.

• Use a cPanel account username as the owner of parked DNS domains
• Preserve DNS when a parked domain becomes a hosting account
• Run a controlled DNS provider acceptance check before assigning customer packages
• Rotate a DNS provider credential across all connections that use it
• Connect HestiaCP DNS with a dedicated access key
• Connect Vultr DNS and allow the WHMCS server's actual outbound address

• cPanel: Manage WHM API tokens
• cPanel: WHM API permission reference
