Drupal Breaks Internal API

[namhost]

I am trying to switch from using the normal api, to using the internal API. Everything has gone swimmingly, except now when I try to run "AddClient". And only if I run it from within Drupal. So this works:

<?php

    require_once("./init.php");
    var_dump($whmcs):

?>

But put those lines inside of a Drupal module, and $whmcs is null. 

I thought it was perhaps a $whmcs or other global variable that is set or used in init.php and somehow that causes the $whmcs to be null. Reason for that is if I actually try to run "AddClient", I end up with this error:

17 {main} {"exception":"[object] (Error(code: 0): Call to a member function get_config() on string at \includes\clientfunctions.php:0)"} []

According to the guys at WHMCS, this is the code being hit:

<?php

    $companyName = $whmcs->get_config('CompanyName');
    
?>

Why in Drupalk would $whmcs become a string? Did it not get initalized? If not, why? 

Any ideas?
