WHMCS Module


Softaculous Virtualizor supports the remote creation of Virtual Machines / VPS. WHMCS can be configured to create the VPS as soon as you accept the Order (Automatically or Manually). We provide a module for WHMCS to enable you to do so. Setting it up is really easy. You can create, delete, suspend a VPS with this module.

The endusers can also manage their VPS through the WHMCS interface without actually logging into Virtualizor.

Note : This module (version 2) requires Virtualizor 2.8.0+ on the master.
The existing plans created on “WHMCS Module 1” will be backward compatible. Any VM which is created from WHMCS module, we recommend that to do not make any changes from Virtualizor Panel. It will affect the integrity. Like adding multiple disk from Virtualizor panel.


Download the Virtualizor WHMCS module from HERE. (Last updated : August 20, 2019)
Unzip it and upload the folder virtualizor (the folder itself), in your /path/to/whmcs/modules/servers/ Directory.
Please make sure that the upload was done properly and the following folder exists :


Virtualizor uses ports from 4081 – 4085. If there is any firewall restricting this, you will need to allow these ports.

Servers Key

Virtualizor generates a Unique Key and Key Pass when its installed on the server.
You will need the servers Key and Key Pass to add the server to WHMCS.
This information can be found from the Virtualizor Admin Panel -> Configuration -> Server Info

Adding Server to WHMCS

Note : Only Master server needs to be added on WHMCS.

To add the Virtualizor Server to WHMCS login to WHMCS Admin Panel Then go to WHMCS Admin Panel -> Setup -> Servers -> Add New Server
Fill the form as shown in the below images :

Creating a Product

Now, you will need to create a product.


To do so go to WHMCS Admin Panel -> Setup -> Products/Services -> Create a New Product
Fill in the details as per the following image and specify the Products Name of your choice .

Module Settings

The WHMCS module has been updated to a new and simple version. It includes selecting the module name and setting up the fields as shown in the image below:

The Fields are:

  • Virtualizor Server : Select the type of virtualizor server where you want to create your VPS.
  • Type : Select the type of Virtualization being used.
  • Select Plan : Select plan which you have created on virtualizor panel.
  • Default Node/Group: Select the Server or node Group or any individual server. (NOTE : [G] denotes the group)
  1. Select the Virtualizor server and then type of virtualization.
  2. After selecting above two fields you have to click on Save Changes. Once the changes are saved, you will get the list of Plans. Until then Plans will be empty.
  3. Select Virtualizor Plan (as created on your Virtualizor Master) and Default Node/Group.
    If you haven’t created a Virtualizor Plan you will need to do so as following :

If you want to know more about adding a Plan click on this link Add a Plan

Custom Fields

Now Click on the Custom Fields Tab and fill in the form as per the following image

Just for your information the vpsid is the VPS ID as per the Virtualizor Database and needs to be stored for any future action like Terminate, Suspend, etc. Please fill it as per the above Image.

The OS field is the List of Operating System Templates on your server. Virtualizor provides templates to its users. Its a COMMA seperated value. This will allow the USER to choose the OS when he is signing up for the VPS. Also the list should be the names as listed in the Virtualizor Admin Panel -> Media -> OS Templates. Again, use the Name and not Filename as seen in the Virtualizor Admin.

The ISO field is to display list of ISO images to your clients. This field will allow users to choose the ISO image while signing up for any plan.

The node_ram_select field is an optional field. This field is useful when you want to choose servers (where your VPSs are going to be created) based on FREE RAM among your servers.

NOTE : Please add ‘none’ value when you add ISO and OS field. (Please refer the screenshot above)

NOTE : ISO option is not supported for OpenVZ and XEN-PV VPS.

Configurable Options [OPTIONAL]

You can add the Configurable Options as per your requirements or exclude one or more of the options below if you do not need it.

Note : The order of preference for selection of Configurable Options is first i.e. If a Product/Service has (lets say) Ram defined as 512 MB and you have also created a Configurable Option with variable Ram options, then the users chosen Ram value from configurable options will be used and not the ram value in Product/Service.

Following are the Configurable Options available in Virtualizor WHMCS module.

  • Number of IPs
  • Number of IPv6 Address
  • Number of IPv6 Subnet
  • Number of Internal IP Address
  • Space

Additional Params : (Since 3.0.0+)

If these parameters are added as configurable option then VM(s) will be created with Plan Value + Configurable option value.
For e.g. If VPS plan has space defined as 5GB and additional_space configurable option is added as 20GB, and while ordering if this 20GB option is selected, then VM will be created with 25GB.
You can use the following parameters as additional param :

  • additional_ram
  • additional_space
  • additional_bandwidth
  • additional_cores
  • additional_num_ips
  • additional_num_ips_int
  • additional_num_ips6

NOTE : You must enter the BuycPanel Login and API Key in virtualizor_conf.php file.

Control Panel : Control Panel as an individual Configurable Option :

The above will just have the control panel installed in the newly created VPS. It will not license the Control Panel. Please do not confuse with the BuycPanel option described above.

NOTE : The configurable option values should be exactly as mentioned in each configurable option above, if you want to add a description to the Configurable option then you need to add a “|” (pipe) after the value followed by the description. For example for a configurable option of disk space if you want to add a description like GB or TB it should look like “10 | 10 GB”.

Custom Code Integration

If you want to add your custom code as a hook to execute after order processing, you can do it by putting your code custom.php. You have to put your code in virtualizor module directory (i.e. /path/to/whmcs/modules/servers/virtualizor/custom.php)
While handling the error please use the variable $custom_error


The callback feature (Admin Panel -> Configuration -> Master Settings -> Callback Settings) allows Virtualizor to notify WHMCS when a specific action is performed.

NOTE : This functionality requires Virtualizor version 2.8.5

The following callback actions are supported for VPS(s):

  • Suspend – It will set VM as suspended in WHMCS.
  • Unsuspend – It will set VM as unsuspende in WHMCS.
  • Terminate – It will set VM as Terminated in WHMCS.
  • Change Hostname – It will change the Hostname in WHMCS for VM.
  • Change IP(s) – It will change the IPs (Assigned IPs as well) in WHMCS for VM.
  • Enable login for WHMCS User – It will enable the user to login with same credential WHMCS credential in Virtualizor cloud panel login.
  • Enable WHMCS Invoicing – This will create the Cloud user invoice in WHMCS.

1) For callbacks to work edit the callback.php script within the /path/to/WHMCS/modules/servers/virtualizor/ folder on your WHMCS installation.
2) Edit the script and set the 3 required security variables:

// Any Admin User in WHMCS
   $admin_user = "admin";

   // The Hash Key in WHMCS (As shown in Virtualizor Admin Panel -> Configuration -> Master Settings -> Callback Settings)
   $hash_key = "";

   // The Virtualizor Master IP
   $connection_ip = "";

3) For more security rename the script to a filename of your choice.

NOTE: If you are enabling an option Enable login for WHMCS User, you will need to configure the file named as perform_actions.php same as callback.php
Please do not change the filename to any other file name. It must be perform_actions.php only.

Disable Enduser Operations

Admin can disable some of the options related to Virtualizor Client operations from WHMCS Enduser panel.

  • Change Hostname
  • Backup/Restore
  • OS Reinstall
  • Control Panel Install

You need to do manual changes in Configuration file to disable the settings, Please open the configuration file “virtualizor_conf.php” provided with the module and change the values of respective fields. (See “Enable/Disable Display Enduser Operations” Section)
