带标签的Mailchimp API订阅

Question

我想通过mailchimp api订阅带有一个或两个标签的电子邮件。

$authToken  = 'xxx';
                $list_id    = 'xxx';

                $postData = array(
                    "email_address" => "$email", 
                    "status" => "subscribed", //subscribed -> direkt eintragen, pending mit double opt in
                    "merge_fields" => array(
                    "tag" => "tag_eins")
                );

                // Setup cURL
                $ch = curl_init('https://us19.api.mailchimp.com/3.0/lists/'.$list_id.'/members/');
                curl_setopt_array($ch, array(
                    CURLOPT_POST => TRUE,
                    CURLOPT_RETURNTRANSFER => TRUE,
                    CURLOPT_HTTPHEADER => array(
                        'Authorization: apikey '.$authToken,
                        'Content-Type: application/json'
                    ),
                    CURLOPT_POSTFIELDS => json_encode($postData)
                ));

                $response = curl_exec($ch);

除了标签之外，其他方法都可以正常工作。列表中存在标签“ tag_eins”。 感谢您的帮助。
