我该如何解决Hubspot API探针

Question

我已添加此PHP代码以在Hubspot CRM联系人列表上创建自定义属性。 每次我都尝试过，但没有成功。尽管没有错误，但没有显示在HubSpot联系人列表中。该代码有什么问题，请告诉我。谢谢

    $company='demo-content1';
    $fname='demo-content1';
    $lname="Demo-content";
    $phone='demo-content1';
    $email='demo-content1';
    $address='demo-content1';
    $city='demo-content1';
    $code='demo-content1';
    $info='demo-content1';
    $totalsession='demo-content1';
    $totalcost='demo-content1';
    $radio1='demo-content1';


    $contact_data = array(
        "fname" => $fname,
        "lname" => $lname,
        "email" => $email,
        "phone" => $phone,
        "info" => $info,
        "code" => $code,
        "city" => $city,
        "radio1" => $radio1,
        "address" => $address,
        "totalsession" =>$totalsession,
        "company" => $company
    );

    $ans_hubspot = new ans_hubspot();
    $ans_hubspot->contact_create($contact_data);
    $ans_hubspot->list_assign_contact("2", $contact_data["phone"]);
