# How to Integrate Help.Center Chat Widget with WHMCS This guide shows you how to seamlessly integrate the Help.Center [https://help.center] live chat widget into your WHMCS site and personalize the experience for your logged-in clients. WHAT THIS INTEGRATION DOES * Embeds the Help.Center chat widget on all WHMCS client pages. * Automatically fills in client name, email, and ID when logged in. * Keeps data private by not exposing anything to logged-out visitors. STEP-BY-STEP INSTALLATION 1. Access Your WHMCS Files Log in to your hosting environment and navigate to the following folder in your WHMCS installation: /includes/hooks/ 2. Create a New File Create a file named: helpcenter_userdata.php 3. Add the Following Code Paste this code into the file: '; // Add client info if user is logged in if ($vars['loggedin']) { $clientEmail = addslashes($vars['clientsdetails']['email']); $clientName = addslashes($vars['clientsdetails']['fullname']); $clientId = addslashes($vars['clientsdetails']['id']); $script .= << window.helpcenter = window.helpcenter || {}; window.helpcenter.ready = function() { window.helpcenter.setUserData({ email: "{$clientEmail}", name: "{$clientName}", userId: "{$clientId}" }); }; HTML; } return $script; }); Please remember to replace your-domain with the actual subdomain of your help.center, e.g., if your domain is hosting.help.center your data-domain value will be "hosting". RESULT * When a client logs in, the chat widget appears and is pre-filled with their details. * When no one is logged in, the widget still appears, but without any user data. * This makes it easy for your team to assist users more efficiently. SECURITY & PRIVACY * Client data is only used on the frontend and never exposed to unauthorized users. * The script loads asynchronously so that it won’t slow down your page. NEED HELP?
