Help Needed with Custom WHMCS Auth0 SSO Integration

[yrmallu]

Dear WHMCS community,

I am trying to implement Single Sign-On (SSO) functionality between my existing application and WHMCS using Auth0 as an identity provider. To accomplish this, I have developed an addon module in WHMCS which uses the Auth0 PHP SDK acquired through Composer.

Despite following recommended steps and practices and conducting extensive troubleshooting, I continue to face challenges with implementing this feature.

Specifically, I am encountering the following issues:

1. When calling $auth0->getUser(), I receive a null value. This suggests that there might be an issue with session handling, despite me taking measures to ensure PHP sessions are correctly configured and that session data should persist across requests.

2. I am running into GuzzleHttp package compatibility issues, as evident by PHP errors related to GuzzleHttp. I have tried various solutions, including updating all Composer package dependencies to their latest versions and ensuring compatibility between package versions, but this issue persists.

Here is some more information about my environment:

1. WHMCS version: 8.10.1
2. PHP version: 8.1.2

I am looking forward to any guidance and assistance you can provide on this matter.

Hello : )

We did exactly this with Cloudflare Access for our admin using a custom WHMCS hook:

    if(defined('ADMINAREA') && ADMINAREA && isset($_COOKIE['CF_Authorization'])) {
        
        if (basename($_SERVER['SCRIPT_NAME']) == 'logout.php') {
            $auth = new WHMCS\Auth();
            $auth->logout();
            header('Location: /cdn-cgi/access/logout');
            exit;
        }
        
        if (<redacted> && ($data = get_query_vals("tbladmins", "id", array("email" => <redacted>)))) {
            $auth = new WHMCS\Auth();
            $auth->getInfobyID($data['id']);
            $auth->setSessionVars();
            $auth->processLogin();
        }
    }

I redacted some of our code but I hope this gives you an idea on how to proceed.

Thanks.

Hello,

 

Have you installed GuzzleHttp  in your addon or using the Guzzlehttp coming along with whmcs?

Hi,

I have installed Auth0 PHP SDK version 8.2 and it's installed all its dependencies. I didn't install GuzzleHttp  externally.
