In this article, We will get all the lists from a Mailchimp account using API 3.0, for this I'm going to use CURL request. We will use GET request using CURL to get all the lists.

Mailchimp is an email marketing service. It is an American company founded in 2001.

To add subscriber in a list you will need mailchimp account API_KEY. I'm using the following function to view all lists from a mailchimp account.

<?php

function curlRequest( $url, $request_type, $api_key, $data = array() ) {
	if( $request_type == 'GET' ) 
	$url .= '?' . http_build_query($data); 
	$mch = curl_init(); 

	$headers = array(
		'Content-Type: application/json',
		'Authorization: Basic '.base64_encode( 'user:'. $api_key ) 
	);

	curl_setopt($mch, CURLOPT_URL, $url ); 
	curl_setopt($mch, CURLOPT_HTTPHEADER, $headers);
	curl_setopt($mch, CURLOPT_RETURNTRANSFER, true);
	curl_setopt($mch, CURLOPT_CUSTOMREQUEST, $request_type);
	curl_setopt($mch, CURLOPT_TIMEOUT, 10);
	curl_setopt($mch, CURLOPT_SSL_VERIFYPEER, false);
	if( $request_type != 'GET' ) {
		curl_setopt($mch, CURLOPT_POST, true); 
		curl_setopt($mch, CURLOPT_POSTFIELDS, json_encode($data) );
	} 
	return curl_exec($mch);
}

$api_key = 'API KEY HERE'; 
$data = array('fields' => 'lists');
$url = 'https://' . substr($api_key,strpos($api_key,'-')+1) . '.api.mailchimp.com/3.0/lists/'; 
$result = json_decode( curlRequest( $url, 'GET', $api_key, $data) );

if( !empty($result->lists) ) {
	echo '<ul>'; 
	foreach( $result->lists as $list ){
		echo '<li value="' . $list->id . "'>' . $list->name . ' (' . $list->stats->member_count . ')</li>';
	}
	echo '</ul>';
}
?>
