Linking to WHMCS is one of the first things to do after you set up WHMCS. You can create login or product links for the Client Area, a shortcut to a ticket submission form, or an order form purchase link.

• For integrating a domain availability check, login form, or domain purchase link, see Utilities > Integration Code within your WHMCS Admin Area for copy-paste ready code.
• You may also want to refer to the Data Feeds functionality.

Client Area and Shopping Cart Links

To link to the Client Area, allowing the user to manage their client account:

http://www.example.com/whmcs/clientarea.php

If the user is not already logged in, this link will first direct them to a login prompt.

To link directly to the active shopping cart:

http://www.example.com/whmcs/cart.php

This link will go directly to the default product group.

Cart and Product Links

The Links tab when you click Edit for a product at Configuration () > System Settings > Products/Services or, prior to WHMCS 8.0, Setup > Products/Services > Products/Services displays various links to the product. You can use these links to direct clients to a specific page or to load the product into their cart and immediately take them to the configuration step for that product.

Product Link Tab Links

You can find the following URLs here:

• Direct Shopping Cart Link — The product is added to the shopping cart and the visitor goes directly to the configuration page, if applicable.
• Direct Shopping Cart Link Specifying Template — The product is added to the shopping cart and the visitor goes directly to the configuration page using a specified template.
• Direct Shopping Cart Link Including Domain — The product is added to the shopping cart and the visitor goes directly to the domain selection page.
• Product Group Cart Link — The visitor goes directly to the product group page.
• Product URLs — The visitor goes directly to the Direct Shopping Cart Link URL destination.
  • Product URLs also track the number of visits for each product URL.
  • When you delete a product URL, the URL will become nonfunctional.

For more information, see Products and Services and Friendly URLs.

Constructing Additional Links

To link to a preselected product with an annual billing cycle, add a billingcycle value:

http://example.com/whmcs/cart.php?a=add&pid=1&billingcycle=annually

To link to a preselected product with a domain, add sld and tld values:

 http://example.com/whmcs/cart.php?a=add&pid=1&sld=google&tld=.com

To link to a preselected product with a subdomain, add domainoption and sld values:

 http://example.com/whmcs/cart.php?a=add&pid=1&domainoption=subdomain&sld=google

To automatically apply a promotion code to the order, add a promocode value alone or with any of the cart links:

 http://example.com/whmcs/cart.php?promocode=xxxxxxx

To link directly to an individual product group, add a gid value with the ID of the product group, or use the URL specified at Configuration () > System Settings > Products/Services or, prior to WHMCS 8.0, Setup > Products/Services > Products/Services:

 http://example.com/whmcs/cart.php?gid=1

To link to the cart and specify an order form template to use, add a carttpl value with the order form template name:

 http://example.com/whmcs/cart.php?carttpl=boxes

To link to a product bundle, add a bid value with the ID of the bundle:

 http://example.com/whmcs/cart.php?a=add&bid=X

Configurable Options

You can also create your own configurable options.

To create a configurable option URL:

1. Step through the order process normally until you reach the product configuration step.
2. Right click and select View Source.
3. Retrieve the field names and value IDs. You can use these in your direct link URLs.

For example:

<p class="cartsubheading">Configurable Options</p>
<p>This product or service has some options that you can choose to customise your
order.</p>
 
<div class="cartbox">
<table cellspacing="0" cellpadding="0">
<tr><td>Disk Space:</td><td width="5"></td><td>
<input type="text" name="configoption[1]" value="100" size="5"> x 1MB $0.00USD
</td></tr>
</table>
</div>

You would then use this URL:

http://example.com/whmcs/cart.php?a=add&pid=1&configoption[1]=100

This would set the value of the first configurable option to 100.

Custom Fields

Custom product fields are almost exactly the same. The following link would prefill the custom field option, the day of the week, with the value Friday:

 http://example.com/whmcs/cart.php?a=add&pid=5&cf_dayofweek=Friday

It's possible to skip the configuration page entirely if you have defined all the configuration values in the URL by adding &skipconfig=1 to your order URL. If there is missing configuration data, this would generate an error and force the client to edit the configuration. For example:

 http://example.com/whmcs/cart.php?a=add&pid=5&cf_dayofweek=Friday&skipconfig=1

Addons

You can link to the order form with preselected addons using a URL like this:

http://example.com/whmcs/cart.php?a=add&pid=1&addons[1]

The number is the ID of the addon you specified.

You can add multiple addons in this format:

http://example.com/whmcs/cart.php?a=add&pid=1&addons[1]&addons[2]

Setting the Language or Template via the URL

You can set the language or template to display to the user with the link you use. Here are some examples:

http://example.com/whmcs/index.php?systpl=portal
http://example.com/whmcs/index.php?language=Spanish
http://example.com/whmcs/index.php?systpl=portal&language=Spanish
http://example.com/whmcs/cart.php?systpl=portal&language=English&gid=1
http://example.com/whmcs/cart.php?systpl=portal&language=Spanish&a=add&pid=1

You can combine these, use them on any page, and use them with the direct order links.

Specifying Currency in a link

You can link to the order form with a preselected currency (and, optionally, a language) using a URL like this:

Selecting Currency ID 1

 http://example.com/whmcs/cart.php?currency=1

Selecting Currency ID 2 and the Spanish language

 http://example.com/whmcs/cart.php?currency=2&language=Spanish

The ID of a currency is the unique ID for it within the tblcurrencies database table. You can find this within the database or by examing the number at the end of the URL when editing the currency within the Admin Area.

Support Ticket Links

You can link to the create ticket page with a number of predefined settings, all of which are interchangeable.

To define the ticket subject, use a link like this:

http://example.com/whmcs/submitticket.php?step=2&deptid=1&subject=Subject%20goes%20here...

You can also define a name and email address:

http://example.com/whmcs/submitticket.php?step=2&deptid=1&name=Jeff&email=jeff@example.com

Integrating The Login Form into your Website

See Utilities > Integration Code in the WHMCS Admin Area for copy-and-paste ready code for adding a client's login form to any page of your site.

In WHMCS version 8.1 and above, enhanced security around login forms means that to leverage an external login form that posts data to dologin.php, the line below must be added to the configuration.php file:

$allow_external_login_forms = true;

Integrating a Domain Availability Check into your Website

See Utilities > Integration Code within the WHMCS Admin Area for copy-and-paste ready code for adding a domain lookup form to any page of your site.

Displaying Announcements on your Site

Announcements are available in RSS feed format. This is the recommended way of retrieving and displaying announcements in an external system or page.

For convenience, on a local site, you may wish to retrieve announcements directly from the database. The following code sample demonstrates one method:

<?php
  
use WHMCS\Database\Capsule;
  
require_once 'members/init.php';
  
$data = Capsule::table('tblannouncements')
            ->where('published', '!=', '0')
            ->where('published', '!=', '')
            ->orderBy('date', 'DESC')
            ->limit(3)
            ->get();
  
foreach ($data as $announcement) {
    $id = $announcement->id;
    $date = $announcement->date;
    $title = $announcement->title;
    $body = $announcement->announcement;
  
    $date = fromMySQLDate($date);
  
    echo "<strong>{$title}</strong><br />"
        . "Posted on {$date}<br /><br />"
        . $body . "<br /><br />";
}

This code assumes that you store WHMCS in the members subdirectory. Update the file include path for your setup.
