Adding a cPanel/WHM Server

The following steps guide you through the process of setting up a cPanel/WHM server in WHMCS for cPanel Hosting Accounts.

  1. You need to begin by creating a Server for your cPanel products to be assigned to in WHMCS
  2. To do this navigate to Setup > Products/Services > Servers and click on Add New Server
  3. Enter the server name, IP address, select the server type "cpanel" from the dropdown menu
  4. Enter your WHM username into the username field
    WHM API Setup
  5. Login to WHM and navigate to Development >> Manage API Tokens
  6. Click Generate Token
  7. Enter a name for your token, such as "WHMCS"
    1. For assistance configuring the WHM API token privileges, see our API Token Permissions section below.
  8. Click Save and copy your API Token
  9. Return to the WHMCS server configuration page and paste the newly generated API Token into the corresponding field.
  10. Ticking the SSL Mode checkbox is also recommended, but all other fields are optional
  11. The default port will be displayed. If your server is configured to communicate on a different port, tick the Override with Custom Port checkbox and enter it into the Port field. For more information refer to Server Port Overrides.
  12. Click Create Server to complete the process and add your new cPanel Server
  13. If this is the only cPanel server listed afterwards, click on the name and ensure it results in an asterisk (*) next to it. This ensures it is the default and used when any other non-specific configuration (server groups) doesn't apply.

Setting Up a cPanel Package

cPanel Module Settings
Adding a Package in WHM

To setup a cPanel package, go to Setup > Products/Services > Products/Services. From there, you can create the product and configure the general settings and pricing info as normal. When it comes to the Module Settings tab, select "cpanel" in the module dropdown field and then for a shared hosting package:

Simple Mode

This section describes a feature available in version 7.0 and above

  1. A list of the available packages configured in WHM will be populated into the WHM Package Name field.
  2. Select the package you wish to be created when this product is ordered
  3. And then finally as with all products you have the option of choosing the automatic setup option you want for new orders, be it immediately as soon as the order is placed, as soon as the initial payment has been received (recommended) or waiting until an admin manually reviews & accepts the pending orders
  4. Click Save Changes

Advanced Mode

Advanced Mode

There is also the option to define custom packages - you can do that by clicking the Switch to Advanced Mode link. Advanced mode presents various options to customise the way the hosting account is created on the cPanel server. One of the possible configurations allows for quotas to be specified on a per-account basis rather than at a per-package level (You will need root access for this to work). To achieve this:

  1. Leave the WHM Package Name field empty
  2. Enter vales in the Web Space Quota and Bandwidth Limit fields.
  3. Define the individual limits into the fields the module settings page. If a field is left blank, WHMCS will not send a value to cPanel which will result in a quota being set to unlimited for that item.
  4. Max Addon Domains is the last field that applies to shared hosting accounts in the list.

For a reseller package

Creating an ACL List
cPanel Reseller Module Settings
  1. Set the settings for the resellers own hosting account as above with one difference, the Product Type setting must be Reseller Account.
  2. The fields from "Limit Reseller by Number" onwards specify reseller settings so from there you can set the resellers limits by number or disk space, these are explained below.
  3. The Reseller ACL List is required and defines what features inside WHM the reseller is allowed to use. To setup an ACL list, WHM doesn't offer a way without setting up a reseller so inside WHM go to the Reseller Center and activate a domain as a reseller, then proceed to the Edit reseller privileges & nameservers page and enter a name to save the feature selections before saving.
  • Limit Reseller by Number - Specifies the maximum number of cPanel accounts the reseller can create or...
  • Limit Reseller by Usage - Alternately limit the disk space and bandwidth the reseller has to assign to their customers using the following two options
  • Reseller Disk Space - The disk space the reseller has to share amongst their accounts
  • Reseller Bandwidth - The bandwidth the reseller has to share amongst their accounts
  • Allow DS Overselling - Tick to allow resellers to assign more disk space to accounts than they actually have
  • Allow BW Overselling - Tick to allow resellers to assign more bandwidth to accounts than they actually have
  • Reseller ACL List - See below
  • Configure Nameservers - Tick this option to give the reseller their own nameservers based upon their domain name instead of using your nameservers. Ie.,
instead of
  • Reseller Ownership - When ticked the reseller will own their own account. A package doesn't necessarily need to be setup, but you would need to define some limits for the client account created, perhaps 1MB disk and bandwidth so the client then changes their account to one of their own packages.

Per Account Billing

This section describes a feature available in version 7.9 and above

Resellers can be billed for the number of cPanel hosting accounts they provision. You can choose whether to include a certain number of sub-accounts in the price and only charge for exceeding a certain limit, offer tiered pricing, or charge a for every sub-account created.

We recommend offering sub-account usage billing only on products with a monthly billing cycle

Enable Usage Billing
  1. To use this feature, toggle On the Sub-Accounts Billing Metric
  2. Click the Configure Pricing link to set the pricing for the Sub-Accounts the reseller consumes.
  3. Click Save

When a client orders this product, WHMCS will track the number of sub-accounts created by the reseller. On the service's Next Due Date, a snapshot of the current volume of sub-accounts created is recorded and the cost added to the service's renewal invoice.

A guide with pricing examples is available here

Usage Billing is a powerful feature. More information on the terms used and possible configurations are explained in the Usage Billing Documentation.

Other Options

  • Add Prefix to Package - Add the username_ prefix to the package name when the account is created on the server. This is useful when using multiple servers with the same package name, but different username.


Login to cPanel Link

The login to cPanel link displayed in the client area is based upon the server hostname if available, if not, the IP address will be used. The usage of http and https login links depends upon the state of the "Secure" checkbox in the server configuration eg. When ticked, the https link with port 2083 is used.

The login to control panel link displayed in the admin area is based upon the server hostname if available, if not, the IP address will be used. The usage of http and https login links depends upon the state of the "Secure" checkbox in the server configuration eg. When ticked, the https link with port 2087 is used. It uses the xfercpanel function, so when prompted, enter your WHM login details (not the client's cPanel details) and you will be logged into the client's account with reseller privileges.

Reseller Usage Calculation

Reseller usage limits and reporting is based on the behaviour of WHM's design & implementation of a "Reseller" account type. Most notably, resellers owned by root will not have their own usage aggregated into such boundary calculations.

WHMCS Connect

WHMCS Connect allows you and your administrators to quickly and easily access the control panels of all the servers configured in your WHMCS installation that support Single Sign-On, enabling you and your staff to administer and make changes without ever needing to re-authenticate.

For information on the benefits of WHMCS Connect and how to configure this functionality refer to this page.

API Token Permissions

With API Tokens for cPanel/WHM, it is possible to restrict what actions an API Token can perform. For WHMCS to be able to perform all the operations it supports, the following permissions are required:

basic-whm-functions basic-system-info cpanel-api
create-acct create-user-session suspend-acct
upgrade-acct kill-acct passwd
acct-summary list-accts show-bandwidth
cpanel-integration list-pkgs ns-config
edit-mx manage-api-tokens ssl-gencrt

When using the Configurable Package Addon, the "edit-account" permission will need to be enabled. For reseller products, the "Everything" permission needs to be enabled as the reseller API functions on a cPanel server require root access to work.

Keep DNS Zone on Termination

When terminating a cPanel/WHM account via the WHMCS admin area, an option is provided to "Keep DNS Zone".

Selecting this option will terminate the account on a cPanel/WHM server while preserving the DNS Zone Record. Use this option where you wish to terminate the account but preserve the DNS records. Common use cases for this include scenarios such as account migration where DNS forwarding is being used.

Please Note: You will not be able to re-create a new account on the server using the same domain while a DNS Zone exists for it. Attempting to provision the domain again will result in an error and you must delete the DNS Zone to be able to successfully provision a new account.

Common Problems

You do not have permission to use Selected Package

If you receive this error when trying to create an account then you need to correct the Packages Name setting. To do this, go to Setup > Products/Services > Edit > Module Settings on the package where you are receiving the error. Where it asks for the WHM Package Name, you must enter this exactly as it appears in WHM - which should be in the format username_packagename.

Package Not Allowed or Exceeded Resource/Account Allocation

This error most likely means you only have reseller access to your server and are trying to create an account without a valid package name. You need to make sure the WHM Package Name in the product configuration of WHMCS matches exactly what is setup in your WHM.

Resellers are not permitted to create subdomains of the server's main domain

This means no domain has been selected and is missing. Ensure the product has a domain name entered. You may need to enable Require Domain in Setup > Product/Services > Edit.

Unable to validate setting for language: english

cPanel/WHM have made a number of changes to their API in the latest versions that are not backwards compatible. Therefore it is no longer possible to use an old version of WHMCS with the latest version of cPanel. You will need to upgrade your WHMCS install to version 4.2.1 or above.

Sorry, that username is reserved

cPanel/WHM does not allow usernames to contain the phrase "test" amongst others, so when this error occurs, simply change the username under the client's products/services tab and run the Create Module Command again.

Sorry, a group for that username already exists

An account with this username already exists on the server. This error can occur on shared servers even when you do not have an account with this username under your reseller account another reseller on the same server may be using it already.

To resolve, navigate to the client's Products/Services tab, change the Username, click Save Changes and finally click the "Create" Module Command button.

Login Failed

There are two possible causes for this error:

  1. The login details under Setup > Servers > Edit are incorrect. Please ensure you are using either the username + access hash combination or the username + password combination and that the login details are correct.
  2. The Brute Force Protection settings are preventing WHMCS from creating/suspending/terminating accounts via the cPanel API. Please adjust the BFP settings in WHM.

No user name supplied: "username" is a required argument

This means the username under the client's Products/Services tab is empty.

You should enter a username, save changes and try module creation again. Also ensure Setup > Products/Services > Products/Services > Edit > Require Domains is ticked to avoid this in future.

Action Failed Unable to auto-login. Please contact support

This error also means the username under the client's Products/Services tab is empty.

You should enter a username, save changes and try module creation again. Also ensure Setup > Products/Services > Products/Services > Edit > Require Domains is ticked to avoid this in future.

WHM Username is missing for the selected server

Seeing this error when attempting to provision a hosting account is caused by a server balancing misconfiguration. Ie. no server is selected upon which the account should be created. For troubleshooting steps for this particular issue, please refer to this article

An Unknown Error Occurred after updating to cPanel 74

After updating to cPanel 74, every module command performed results in a "An unknown error occurred" message. Inspecting the Module Debug Log reveals that a WHM 404 error page is being returned by the server.

This is caused by the deprecation of the cPanel XML API in version 74. To use the newer cPanel JSON API, it is necessary to update to WHMCS 7.3 or above.
