2. Getting Started

PHP
<?php
require_once(__DIR__ . '/vendor/autoload.php');
$client = new GuzzleHttp\Client();

$apiInstance = new sendpost\api\EmailApi($client);

$x_sub_account_api_key = 'your_api_key'; // Sub-Account API Key
$email_message = new \sendpost\model\EmailMessage(); 
$email_message->setSubject('Hello World');
$email_message->setHtmlBody('<strong>it works!</strong>');

$from = new \sendpost\model\From();
$from->setEmail('[email protected]');

$to = new \sendpost\model\To();
$to->setEmail('[email protected]');
$email_message->setTo(array($to));
$email_message->setFrom($from);

try {
    $result = $apiInstance->sendEmail($x_sub_account_api_key, $email_message);
    print_r($result);
