php - Adding subscribers to a list using Mailchimp's API v3

Question

I'm trying to add users to a list I've created in Mailchimp but I can't find any code examples anywhere. I've tried figuring out how to use the API but I'm very much a "Look at an example and learn" kind of person.

I've tried using version 2 of the API but nothing seems to be working despite working from examples on the net and Mailchimp says the following about earlier versions of their API on their website:

Versions 2.0 and earlier are deprecated. Only minimal support—bug fixes, security patches—will be available for those versions.

UPDATE 1: I did some further research based on TooMuchPete's answer with regards to the link on Managing Subscribers and altered some code I found here, but it won't work because the function http_build_query() doesn't deal with nested arrays. I'm not sure how to deal with the 'merge_fields' portion of adding a subscriber. My current code is below:

$postdata = http_build_query(
                    array(
                        'apikey'        => $apikey,
                        'email_address' => $email,
                        'status'        => 'subscribed',
                        'merge_fields'  => array(
                            'FNAME' => $name
                        )
                    )
                );

                $opts = array('http' =>
                    array(
                        'method'  => 'POST',
                        'header'  => 'Content-type: application/x-www-form-urlencoded',
                        'content' => $postdata
                    )
                );

                $context  = stream_context_create($opts);

                $result = file_get_contents('https://us2.api.mailchimp.com/3.0/lists/<list_id>/members/', false, $context);

                var_dump($result);
                die('Mailchimp executed');

UPDATE 2: I've now resorted to using curl and I've managed to get something almost working. The data sends through to Mailchimp but I'm receiving the error "Your request did not include an API key." I'm guessing I need to authenticate as mentioned here. I've tried adding it to the http header which hasn't worked. See my code below:

$apikey = '<api_key>';
                $auth = base64_encode( 'user:'.$apikey );

                $data = array(
                    'apikey'        => $apikey,
                    'email_address' => $email,
                    'status'        => 'subscribed',
                    'merge_fields'  => array(
                        'FNAME' => $name
                    )
                );
                $json_data = json_encode($data);

                $ch = curl_init();
                curl_setopt($ch, CURLOPT_URL, 'https://us2.api.mailchimp.com/3.0/lists/<list_id>/members/');
                curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json/r/n
                                                            Authorization: Basic '.$auth));
                curl_setopt($ch, CURLOPT_USERAGENT, 'PHP-MCAPI/2.0');
                curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
                curl_setopt($ch, CURLOPT_TIMEOUT, 10);
                curl_setopt($ch, CURLOPT_POST, true);
                curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
                curl_setopt($ch, CURLOPT_POSTFIELDS, $json_data);                                                                                                                  

                $result = curl_exec($ch);

                var_dump($result);
                die('Mailchimp executed');

Answer 1

リストメンバーインスタンスのドキュメントに基づいて、最も簡単な方法はPUT、ドキュメントに従って「新しいリストメンバーを追加するか、メールがリストに既に存在する場合はメンバーを更新する」リクエストを使用することです。

さらにapikey、これは間違いなくjson スキーマの一部ではなく、json リクエストに含めても意味がありません。

また、@TooMuchPete のコメントに記載されCURLOPT_USERPWDているように、以下に示すように基本的な http 認証に使用できます。

次の関数を使用して、リスト メンバーを追加および更新しています。merge_fieldsリスト パラメータによっては、わずかに異なる のセットを含める必要がある場合があります。

$data = [
    'email'     => 'johndoe@example.com',
    'status'    => 'subscribed',
    'firstname' => 'john',
    'lastname'  => 'doe'
];

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;
}

Answer 2

私はそれを働かせました。認証をヘッダーに間違って追加していました:

$apikey = '<api_key>';
            $auth = base64_encode( 'user:'.$apikey );

            $data = array(
                'apikey'        => $apikey,
                'email_address' => $email,
                'status'        => 'subscribed',
                'merge_fields'  => array(
                    'FNAME' => $name
                )
            );
            $json_data = json_encode($data);

            $ch = curl_init();
            curl_setopt($ch, CURLOPT_URL, 'https://us2.api.mailchimp.com/3.0/lists/<list_id>/members/');
            curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json',
                                                        'Authorization: Basic '.$auth));
            curl_setopt($ch, CURLOPT_USERAGENT, 'PHP-MCAPI/2.0');
            curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
            curl_setopt($ch, CURLOPT_TIMEOUT, 10);
            curl_setopt($ch, CURLOPT_POST, true);
            curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
            curl_setopt($ch, CURLOPT_POSTFIELDS, $json_data);                                                                                                                  

            $result = curl_exec($ch);

            var_dump($result);
            die('Mailchimp executed');

Answer 3

これらは良い回答ですが、データを送信してその応答を処理するフォームを取得する方法については、完全な回答から切り離されています。これは、jquery を介して HTML ページから API の v3.0 を使用してメンバーをリストに追加する方法を示します.ajax()。

Mailchimp では:

1. API キーとリスト IDを取得する
2. リストを設定し、リストで使用するカスタム フィールドを確認してください。zipcodeこの場合、 API 呼び出しを行う前に、リストにカスタム フィールドとして設定しました。
3. リストへのメンバーの追加に関するAPI ドキュメントを確認してください。createHTTPPOSTリクエストを使用する必要があるメソッドを使用しています。PUTサブを変更/削除できるようにする場合に必要な他のオプションがここにあります。

HTML:

<form id="pfb-signup-submission" method="post">
  <div class="sign-up-group">
    <input type="text" name="pfb-signup" id="pfb-signup-box-fname" class="pfb-signup-box" placeholder="First Name">
    <input type="text" name="pfb-signup" id="pfb-signup-box-lname" class="pfb-signup-box" placeholder="Last Name">
    <input type="email" name="pfb-signup" id="pfb-signup-box-email" class="pfb-signup-box" placeholder="youremail@example.com">
    <input type="text" name="pfb-signup" id="pfb-signup-box-zip" class="pfb-signup-box" placeholder="Zip Code">
  </div>
  <input type="submit" class="submit-button" value="Sign-up" id="pfb-signup-button"></a>
  <div id="pfb-signup-result"></div>
</form>

重要事項:

1. 一意の ID を指定し、フォームが機能するように属性<form>を忘れないでください。method="post"
2. 最後の行#signup-resultは、PHP スクリプトからのフィードバックを保存する場所であることに注意してください。

重要事項:

1. CURLOPT_USERPWDAPIキーを処理しますが、Mailchimpはこれを行う方法を実際には示していません.
2. CURLOPT_RETURNTRANSFER.ajax() successハンドラーを使用して HTML ページに送り返すことができるような方法で応答を返します。
3. json_encode受け取ったデータで使用します。

JS:

// Signup form submission
$('#pfb-signup-submission').submit(function(event) {
  event.preventDefault();

  // Get data from form and store it
  var pfbSignupFNAME = $('#pfb-signup-box-fname').val();
  var pfbSignupLNAME = $('#pfb-signup-box-lname').val();
  var pfbSignupEMAIL = $('#pfb-signup-box-email').val();
  var pfbSignupZIP = $('#pfb-signup-box-zip').val();

  // Create JSON variable of retreived data
  var pfbSignupData = {
    'firstname': pfbSignupFNAME,
    'lastname': pfbSignupLNAME,
    'email': pfbSignupEMAIL,
    'zipcode': pfbSignupZIP
  };

  // Send data to PHP script via .ajax() of jQuery
  $.ajax({
    type: 'POST',
    dataType: 'json',
    url: 'mailchimp-signup.php',
    data: pfbSignupData,
    success: function (results) {
      $('#pfb-signup-box-fname').hide();
      $('#pfb-signup-box-lname').hide();
      $('#pfb-signup-box-email').hide();
      $('#pfb-signup-box-zip').hide();
      $('#pfb-signup-result').text('Thanks for adding yourself to the email list. We will be in touch.');
      console.log(results);
    },
    error: function (results) {
      $('#pfb-signup-result').html('<p>Sorry but we were unable to add you into the email list.</p>');
      console.log(results);
    }
  });
});

重要事項:

1. JSONデータは転送時に非常に扱いにくいです。ここでは、配列に入れていますが、簡単に見えます。問題がある場合は、JSON データの構造が原因である可能性があります。これをチェックしてください！
2. JSON データのキーは、PHP_POSTグローバル変数で参照するものになります。この場合_POST['email']、 、 などになります。ただし、任意の名前を付けることができます。JSON 転送_POST['firstname']の一部のキーに名前を付けるのは、PHP でそれらにアクセスする方法であることを覚えておいてください。data
3. これには明らかにjQueryが必要です;）

Answer 5

それが誰かに役立つ場合は、 CURLの代わりに Python Requestsライブラリを使用して Python で作業したものを次に示します。

上記の @staypuftman が説明したように、MailChimp からの API キーとリスト ID が必要であり、API キーのサフィックスと URL プレフィックス (つまり us5) が一致していることを確認してください。

# To add a single contact to MailChimp (using MailChimp v3.0 API), requires:
#   + MailChimp API Key
#   + MailChimp List Id for specific list
#   + MailChimp API URL for adding a single new contact

# Note: the API URL has a 3/4 character location subdomain at the front of the URL string. 
# It can vary depending on where you are in the world. To determine yours, check the last 
# 3/4 characters of your API key. The API URL location subdomain must match API Key

バッチ操作の関数の使用とデータ形式:

<?php
$apikey  = 'Your MailChimp Api Key';
$list_id = 'Your list ID';
$servername = 'localhost';
$username   = 'Youre DB username';
$password   = 'Your DB password';
$dbname     = 'Your DB Name';
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
    die('Connection failed: ' . $conn->connect_error);
}
$sql       = 'SELECT * FROM emails';// your SQL Query goes here
$result    = $conn->query($sql);
$finalData = [];
if ($result->num_rows > 0) {
    // output data of each row
    while ($row = $result->fetch_assoc()) {
        $individulData = array(
            'apikey'        => $apikey,
            'email_address' => $row['email'],
            'status'        => 'subscribed',
            'merge_fields'  => array(
                'FNAME' => 'eastwest',
                'LNAME' => 'rehab',
            )
        );
        $json_individulData        = json_encode($individulData);
        $finalData['operations'][] =
            array(
                "method" => "POST",
                "path"   => "/lists/$list_id/members/",
                "body"   => $json_individulData

$api_response = batchSubscribe($finalData, $apikey);
print_r($api_response);
