Independence Day Sale – Save 15% of every WHMCS module

8. Custom Fields

The module uses two WHMCS product Custom Fields. Both are created automatically when you save a product with this module selected — you do not need to create them by hand.

Field Name

Visibility

Purpose

LinodeId

Text

Admin only

Stores the numeric Linode instance ID returned at provisioning. Every subsequent action — power, rebuild, backups, disks, volumes, IPs — uses it to target the right instance.

SSHKey

Textarea

Client-visible, shown on the order form

Public SSH key(s), one per line. Deployed to the root account when the Linode is created. Kept in step automatically with the keys the customer adds or removes on the Client Area SSH Keys page.

Important: Do not rename or delete the LinodeId field, and do not clear its value on an active service. Every post-provisioning action relies on it to identify the instance at Linode. Clearing it makes the Client Area report that the service is not provisioned yet.
