PHP CURL не работает на многомерном массиве

Question

У меня есть скрипт PHP для обновления контактной информации через CURL, он должен сделать 2 обновления, одно для клиентов, 1 для контактов. Клиент работает, но контакты просто обновляют базу данных пробелами, она не оставляет значений, она полностью стирает их, кто-нибудь может увидеть причину этого?

Спасибо

Код ниже: itemid и contactid объявлены в скрипте и работают нормально

//Update Client
$name = "test2 test2";
$address1 = "my house";
$city = "my city";
$state = "my state";
$postal_code = "NE25 8RU";
$work_phone = "01234567";
$first_name = "test2";
$last_name = "test2";
$email = "test@test.com";
$url = urlencode("https://myurl.co.uk/api/v1/clients/$itemid");
$encoded_url = urlencode($url);
$after_encoded_url = str_replace("%2F", "/", $url);
$after_encoded_url2 = str_replace("%3A", ":", $after_encoded_url);
$after_encoded_url3 = str_replace("%3Cbr+/%3E", "/", $after_encoded_url2);
$curl = curl_init(); 

    if (!$curl) {
        die("Couldn't initialize a cURL handle"); 
    }
$headers = [
'Content-Type: application/json',
'X-Requested-With: XMLHttpRequest',
'X-Ninja-Token:token',
];
$cid = (int)$contactid;
$postdata3 = array(
"name" => $name,
"address1" => $address1,
"city" => $city,
"state" => $state,
"postal_code" => $postal_code,
"work_phone" => $work_phone,
"contacts" => array(array(
    "id" => $cid,
    "client_id" => $itemid,
    "first_name" => $first_name,

    curl_setopt($curl, CURLOPT_POST, "PUT === 'POST' ? 1 : 0");
    curl_setopt($curl, CURLOPT_POSTFIELDS, $postdata3);

    curl_setopt($curl, CURLOPT_HTTPHEADER, $headers);

    // Do not check the SSL certificates
    curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, false); 
    curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false); 

    // Fetch the URL and save the content in $html variable

    // Check if any error has occurred 
    if (curl_errno($curl)) 
    {
        echo 'cURL error: ' . curl_error($curl); 
    } 
    else

    // close cURL resource to free up system resources
    curl_close($curl);
