One unique thing about the WePay API is that you can create stub user accounts from your App.

<?php
include './wepay_api.inc';
$W = new WePay($access_token$token_secret);
$user uniqid();
$data = array('name'=>"Test $user"'email'=>"$user@slowgeek.com");
$new_user $W->post('/user/register'$data);
print_r($new_user);
Output
