Product custom fields

Optional WHMCS Integration Customization

  • Create new VPS welcome email template. We have provided a custom email template to use for sending VPS server credentials to enduser when VPS is provisioned (created). This template will utilize merge fields and organize important server details better than the default “VPS/Dedicated Server Welcome Email” template  that is provided with WHMCS.
    • You can add the template from your WHMCS Admin area by navigating to “Setup->Email Templates”
    • Choose to “Create New Email Template”
    • Choose “Product/Service” from the “Email Type” drop-down menu and give the template a unique name
      Create custom vps welcome email template
    • Configure the email sending settings
    • Add a subject for your email (i.e. “New VPS Server Details”)
    • To import  our pre-made template, click “Enable/Disable Rich-Text Editor” button
    • Copy and paste the email template from below:
      Dear {$client_name},
      We are glad to inform you that the virtual machine you ordered has been set up.
      Manager Details
      Username: {$service_username}
      Password: {$service_password}
      Server Details
      Hostname: {$service_domain}
      Main IP: {$service_dedicated_ip} 
      Root Password: {$service_password}
      {if $service_assigned_ips}
      IP Address Allotted:
      You can access your server over SSH. 
      If you are a Windows user, you can use a free SSH client called Putty which can be downloaded from :
    • This is a basic template and you can easily customize or add additional details
  • Instead of creating each VPS product with Custom Field: “OS|Operating System” and drop-down list of all available templates, we recommend creating a “Configurable Options” group with the  “OS|Operating System” configurable option. Please also refer to this article to find more information about using configurable options in WHMCS.
    • Configurable Options group can be assigned to all VPS products (of the same Virtualization)-this will be much more desirable from an administrative perspective, should the available OS templates options ever change.
    • In the event of new OS template available for VPS, you can simply modify this single Configurable Option (assuming the group is assigned to multiple VPS products for same Virtualization), as opposed to editing the custom fields drop-down values for every related VPS product individually.
    • Where to get the values for available OS templates (for KVM virtualization VPS)?
      • Rad Web Hosting keeps a public list of available KVM OS templates in the Knowledgebase, at: VPS Guides -> List of Available OS Templates
      • Use the highlighted values (from the “Name” column) in the below image to for the Configurable Options “OS|Operating System” drop-down values (this must be exactly the same for the automated provisioning to work):
