PHP library for v3 of the Mailchimp API

This library provides convenient wrapper functions for Mailchimp's REST API. The API is documented here.


  • PHP 5.4.0 or greater (7.0 or greater if you wish to use phpunit)
  • Composer
  • Guzzle


Dependencies are managed by Composer. After installing Composer, run the following command from the library root:

composer install --no-dev --ignore-platform-reqs

Or to install with phpunit:

composer install


Get your account information

A basic test to confirm the library is set up and functional.

require 'PATH_TO_LIBRARY/mailchimp-api-php/vendor/autoload.php';
$api_key = 'YOUR_API_KEY';
$mailchimp = new Mailchimp\Mailchimp($api_key);

// Get the account details of the authenticated user.
$response = $mailchimp->getAccount();

// Output the account details.
if (!empty($response) && isset($response->account_id)) {
  echo "ID: {$response->account_id}\n"
  . "Name: {$response->account_name}\n";

Get lists and their interest categories

A more complicated example that takes the response from one API call and uses that data to make another.

require 'PATH_TO_LIBRARY/mailchimp-api-php/vendor/autoload.php';
$api_key = 'YOUR_API_KEY';
$mailchimp_lists = new Mailchimp\MailchimpLists($api_key);

// Get all lists.
$response = $mailchimp_lists->getLists();

if (!empty($response) && isset($response->lists)) {
  foreach ($response->lists as $list) {
    // Output the list name.
    echo "List name: {$list->name}\n";

    // Get the list's interest categories.
    $interests = $mailchimp_lists->getInterestCategories($list->id);

    // Output the names of the list's interest categories.
    if (!empty($interests) && isset($interests->categories)) {
      foreach ($interests->categories as $category) {
        echo "Interest category: {$category->title}\n";


This library includes a PHPUnit test suite.

Running PHPUnit tests

Add Composer's vendor directory to your PATH by adding the following line to your profile. This is dependent on your system, but on a Linux or Mac OSX system using Bash, you'll typically find the file at ~/.bash_profile.

export PATH="./vendor/bin:$PATH"

Bash example:

echo 'export PATH="./vendor/bin:$PATH"' >> ~/.bash_profile
source ~/.bash_profile

Then run PHPUnit:


Mailchimp API Playground

Mailchimp's API Playground provides access to all API methods via a web-based UI. You can use this to test API calls and review data you've sent to Mailchimp.
