I'm creating an app in nodejs to send an email using MailChimp. I've tried to use .0/sendemail.func.php but changed it to use 3.0 api because 1.0 seems to no longer work (big surprise). I've setup my app with

var apiKey = '<<apiKey>>',
        toEmail = '<<emailAddress>>',
        toNames = '<<myName>>',
        message = {
            'html': 'Yo, this is the <b>html</b> portion',
            'text': 'Yo, this is the *text* portion',
            'subject': 'This is the subject',
            'from_name': 'Me!',
            'from_email': '',
            'to_email': toEmail,
            'to_name': toNames
        },
        tags = ['HelloWorld'],
        params = {
            'apikey': apiKey,
            'message': message,
            'track_opens': true,
            'track_clicks': false,
            'tags': tags
        },
        url = '.0/SendEmail';
needle.post(url, params, function(err, headers) {
    if (err) {
                console.error(err);
            }
            console.log(headers);
    }
});

I keep getting a 401 response (not authorized because I'm not sending the API key properly)

I have to use needle due to the constraints on the server.

• javascript
• node.js
• curl
• mailchimp
• needle.js

There is no "SendEmail" endpoint in API v3.0. MailChimp's STS was a pre-cursor to its Mandrill transactional service and may only still work for user accounts that have existing STS campaigns. No new STS campaigns can be created. If you have a monthly, paid MailChimp account, you should look into Mandrill. If not, I've had good luck with Mailgun.

You should use HTTP Basic authentication in MailChimp API 3.0.

needle.get('https://<dc>.api.mailchimp./3.0/<endpoint>', { username: 'anystring', password: 'your_apikey' },
  function(err, resp) {
      // your code here...
});

EDIT

@TooMuchPete is right, the SendMail endpoint is not valid in MailChimp API v3.0. I didn't notice that and I've edited my answer.
