Mandrill- Attachments not sending attachment

问题

I am attempting to send a small rtf attachment through Mandrill. I have created the following json and tried it using the API test page. The attachment is base 64 encoded. The API reports no error and the email comes through but with no attachment. What am I doing wrong?

{
    "attachments": [
    {
        "type": "application/rtf",
        "name": "test.rtf",
        "content": "e1xydGYxXGFuc2lcYW5zaWNwZzEyNTJcZGVmZjBcZGVmbGFuZzIwNTd7XGZvbnR0Ymx7XGYwXGZuaWxcZmNoYXJzZXQwIENhbGlicmk7fX0NCntcKlxnZW5lcmF0b3IgTXNmdGVkaXQgNS40MS4yMS4yNTEwO31cdmlld2tpbmQ0XHVjMVxwYXJkXHNhMjAwXHNsMjc2XHNsbXVsdDFcbGFuZzlcZjBcZnMyMiB0aGlzIGlzIGEgdGVzdCBzZW5kaW5nIGZpbGVccGFyDQp9DQoA"
    }
],
"message": {
    "html": "<html>\r\n<body>test data</body>\r\n</html>\r\n",
    "subject": "Cloud Demo",
    "from_email": "jklovanc@hotmail.com",
    "preserve_recipients": true,
    "text": "",
    "to": [
        {
            "type": "to",
            "name": "",
            "email": "jklovanc@hotmail.com"
        }
    ],
    "from_name": "",
    "headers": {
        "reply-to": "jklovanc@hotmail.com"
    }
},
"key": #mykey#,
"async": false

}

Attachments are part of the message object, so the attachments parameter should be nested under the message instead of at the same level. It should look like this instead:

{
    "message": {
        "attachments": [
            {
                "type": "application/rtf",
                "name": "test.rtf",
                "content": "e1xydGYxXGFuc2lcYW5zaWNwZzEyNTJcZGVmZjBcZGVmbGFuZzIwNTd7XGZvbnR0Ymx7XGYwXGZuaWxcZmNoYXJzZXQwIENhbGlicmk7fX0NCntcKlxnZW5lcmF0b3IgTXNmdGVkaXQgNS40MS4yMS4yNTEwO31cdmlld2tpbmQ0XHVjMVxwYXJkXHNhMjAwXHNsMjc2XHNsbXVsdDFcbGFuZzlcZjBcZnMyMiB0aGlzIGlzIGEgdGVzdCBzZW5kaW5nIGZpbGVccGFyDQp9DQoA"
            }
        ],
        "html": "<html>\r\n<body>test data</body>\r\n</html>\r\n",

<?php

    $res_user_mandrill = $mandrill->messages->send($user_message, $async=false, $ip_pool=null, $send_at=null);

} catch(Mandrill_Error $e) {

}
