Mailchimp API - batch upload - php

Question

I'm trying to import a list of 879 users (in batch) into a Mailchimp list. The library I'm using is: https://github.com/pacely/mailchimp-api-v3.
I've created a Laravel console command to do this. The code is:
<?php
namespace App\Console\Commands;
use Illuminate\Console\Command;
use Illuminate\Support\Facades\DB;
use Illuminate\Support\Facades\Validator;
use Mailchimp\Mailchimp;
use Exception;
class ImportContactsIntoMailchimp extends Command
{
/**
* The name and signature of the console command.
*
* #var string
*/
protected $signature = 'mailchimp:import:contacts';
/**
* The console command description.
*
* #var string
*/
protected $description = 'Import contacts into mailchimp.';
/**
* Create a new command instance.
*
* #return void
*/
public function __construct()
{
parent::__construct();
}
/**
* If an e-mail address starts with this, mailchimp won't allow it
* http://kb.mailchimp.com/lists/growth/limits-on-role-based-addresses
*
* #var array
*/
private $nomail = array(
'abuse#',
'admin#',
'billing#',
'compliance#',
'devnull#',
'dns#',
'ftp#',
'hostmaster#',
'inoc#',
'ispfeedback#',
'ispsupport#',
'list-request#',
'list#',
'maildaemon#',
'noc#',
'no-reply#',
'noreply#',
'null#',
'phish#',
'phishing#',
'postmaster#',
'privacy#',
'registrar#',
'root#',
'security#',
'spam#',
'support#',
'sysadmin#',
'tech#',
'undisclosed-recipients#',
'unsubscribe#',
'usenet#',
'uucp#',
'webmaster#',
'www#'
);
/**
* Execute the console command.
*
* #return mixed
*/
public function handle()
{
$result = DB::table('contacts_billonline')
->select(
'email',
'firstname',
'surname',
'phone'
)
->get();
$batch_count = 250;
$email_column = 'email';
$merge_columns = array(
'EMAIL' => 'email',
'FNAME' => 'firstname',
'LNAME' => 'surname',
'PHONE' => 'phone',
);
$listId = $this->ask('What is the list id?');
// Create our mailchimp connection
$mailchimp_key = config('mailchimp.apikey');
$mc = new Mailchimp($mailchimp_key);
$contact_list = '/lists/'.$listId.'/members';
$total = count($result);
for ($i = 0; $i < $total; $i += $batch_count)
{
$batch = array();
for ($j = 0; $j < $batch_count; $j++)
{
$row_number = $i + $j;
if ($row_number === $total)
{
// If we reached the end of the list, stop trying to add operations
break;
}
// Get the email address from the result for this row
$email = &$result[$row_number]->{$email_column};
// Is this a valid email address? If so add it to the batch
if ($this->isValidEmail($email)) {
$this->info($email);
// Get our merge columns for this row and put them in the array
$merge_fields = array();
foreach ($merge_columns as $key => &$column) {
$merge_fields[$key] = &$result[$row_number]->{$column};
}
$insert_email = array(
'email_address' => $email,
'status' => 'subscribed',
'merge_fields' => $merge_fields,
'tags' => ['Contacts']
);
$batch_operation = array(
'method' => 'POST',
'path' => $contact_list,
'body' => json_encode($insert_email)
);
$batch[] = $batch_operation;
}
}
$body = array();
$body['operations'] = $batch;
$batch_result = $mc->post('/batches', $body);
$this->info($batch_result);
}
}
/**
* Is this is an email address mailchimp would see as valid?
*
* #param $email
* #return bool
*/
function IsValidEmail(&$email)
{
foreach ($this->nomail as &$bad_mail)
{
if (strpos($email, $bad_mail) === 0)
{
return false;
}
}
$validator = Validator::make(
array(
'email' => &$email
),
array(
'email' => 'required|email'
)
);
if ($validator->fails())
{
return false;
}
return true;
}
}
I'm trying to import the users from a database table in batch into Mailchimp.
The API key is set correctly. I'm also trying to set a tag "Contacts" to the subscribers.
The list id is also set correctly.
The problem is that the list isn't imported. The result in terminal is:
{"id":"c48cd17f6d","status":"pending","total_operations":0,"finished_operations":0,"errored_operations":0,"submitted_at":"2019-07-02T10:58:22+00:00","completed_at":"","response_body_url":"","_links":[{"rel":"parent","href":"https://us8.api.mailchimp.com/3.0/batches","method":"GET","targetSchema":"https://us8.api.mailchimp.com/schema/3.0/Definitions/Batches/CollectionResponse.json","schema":"https://us8.api.mailchimp.com/schema/3.0/CollectionLinks/Batches.json"},{"rel":"self","href":"https://us8.api.mailchimp.com/3.0/batches/c48cd17f6d","method":"GET","targetSchema":"https://us8.api.mailchimp.com/schema/3.0/Definitions/Batches/Response.json"},{"rel":"delete","href":"https://us8.api.mailchimp.com/3.0/batches/c48cd17f6d","method":"DELETE"}]}
What am I doing wrong?
