如何通过MailChimp 3.0 api发送电子邮件？

我正在尝试通过 php 中的 mailchimp api 版本 3.0 发送电子邮件，但我没有运气。这是我的代码：

$postString = '{
        "message": {
            "html": "this is the emails html content",
            "text": "this is the emails text content",
            "subject": "this is the subject",
            "from_email": "[email protected] /cdn-cgi/l/email-protection",
            "from_name": "John",
            "to_email": "[email protected] /cdn-cgi/l/email-protection",
            "to_name": "Anton",
            "track_opens": false,
            "track_clicks": false
        }}';

        $ch = curl_init();
        curl_setopt($ch, CURLOPT_URL, $this->api_endpoint);
        curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_BASIC); 
        curl_setopt($ch, CURLOPT_USERPWD, 'drewm:'.$this->api_key);
        curl_setopt($ch, CURLOPT_HTTPHEADER, array('Accept: application/vnd.api+json', 'Content-Type: application/vnd.api+json'));
        curl_setopt($ch, CURLOPT_USERAGENT, 'DrewM/MailChimp-API/3.0 (github.com/drewm/mailchimp-api)');
        curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true );
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, true );
        curl_setopt($ch, CURLOPT_TIMEOUT, $timeout);
        curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, $this->verify_ssl);
        curl_setopt($ch, CURLOPT_POST, true);
        curl_setopt($ch, CURLOPT_POSTFIELDS, $postString);
        curl_setopt($ch, CURLOPT_HTTP_VERSION, CURL_HTTP_VERSION_1_0);

        $result = curl_exec($ch);

        echo $result;

我究竟做错了什么？

您无法像使用 v1 那样从 API v3 发送随机电子邮件。现在，您只能发送以前在 MailChimp 中创建的营销活动，如 LamaDelRay 所述。
