MailChimp API Subscriber Sign Up

Recommended Posts

MailChimp allows you to create sign up forms with their builder, but they can be a pain to style and for some don’t allow enough customization.

The following code is an example of how you can take advantage of the MailChimp API to subscribe new users.  Doing this allows you to then create a custom sign up form and style it easily to match your own look and feel.

This example assumes you’re only passing the First Name, Last Name, and email of a new subscriber.  It’s easy enough to add additional fields, but this will get you started.

First you’ll need to setup an API key in your MailChimp account, so login and navigate to Account -> Extras -> API Keys.

Once you’ve clicked to create a new API key go ahead and copy the API key and place it in your code.

Now you will need to find the list ID.  This is not the ID of the list from the URL.  You need to go to your lists and in the drop down select settings.  Scroll all the way down and here you will find your list ID to replace in the code.

You’re all set, now create your form matching the names from the following script and set your form action to “GET”.

<?php

//Grab Data Variables Passed From Form
$data = [
    'email' => $_GET['email'],
    'status' => 'subscribed',
    'firstname' => $_GET['firstname'],
    'lastname' => $_GET['lastname']
];

syncMailchimp($data);

function syncMailchimp($data)
{
    $apiKey = 'Your API KEY';
    $listID = 'Your List ID';

    $memberID = md5(strtolower($data['email']));
    $dataCenter = substr($apiKey, strpos($apiKey, '-') + 1);
    $url = 'https://' . $dataCenter . '.api.mailchimp.com/3.0/lists/' . $listID . '/members/' . $memberID;

    $json = json_encode([
        'email_address' => $data['email'],
        'status' => $data['status'], // "subscribed","unsubscribed","cleaned","pending"
        'merge_fields' => [
            'FNAME' => $data['firstname'],
            'LNAME' => $data['lastname']
        ]
    ]);

    $ch = curl_init($url);

    curl_setopt($ch, CURLOPT_USERPWD, 'user:' . $apiKey);
    curl_setopt($ch, CURLOPT_HTTPHEADER, ['Content-Type: application/json']);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_TIMEOUT, 10);
    curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'PUT');
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
    curl_setopt($ch, CURLOPT_POSTFIELDS, $json);

    $result = curl_exec($ch);
    $httpCode = curl_getinfo($ch, CURLINFO_HTTP_CODE);
    curl_close($ch);

    return $httpCode;
}
