如何使用API​​將電子郵件地址添加到MailChimp列表

Question

我正在嘗試使用MailChimp API 3.0使用下面的此代碼將電子郵件地址添加到現有列表中，但它始終拋出此錯誤消息。 請任何人告訴我我的代碼有什么問題嗎？

401：您的API密鑰可能無效，或者您嘗試訪問錯誤的數據中心。

碼：

$apikey = "xxxxxxxxxxxxxxxxxxxxxxxx-us9";
$list_id = "xxxxxxxxxx";
$MD5_hashed_email_address = md5(strtolower($to_email));
$auth = base64_encode("user:$apikey");

$data = array(
    "apikey" => $apikey,
    "email_address" => $to_email,
    "status" => "subscribed",
    "merge_fields" => array(
        "FNAME" => $firstname,
        "LNAME" => $surname
    )
);
$json_data = json_encode($data);

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "https://us9.api.mailchimp.com/3.0/lists/$list_id/members/");
curl_setopt($ch, CURLOPT_HTTPHEADER, array("Content-Type: application/json",
    'Authorization: apikey ' . $auth));
curl_setopt($ch, CURLOPT_USERAGENT, "PHP-MCAPI/2.0");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_TIMEOUT, 10);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_POSTFIELDS, $json_data);
$result = curl_exec($ch);

嘗試這個：

curl_setopt($ch, CURLOPT_HTTPHEADER, array("Content-Type: application/json", 'Authorization: Basic ' . $auth));
