get Vendors Registration Information

Hello .
thank you for your good work!

I am using a CRM and want to get vendors data (when they register) into my CRM as leads.
Somehow i was able to rich my goal to get vendor’s name and family and email address but i could not do it for phone , address and other data . I did it by creating a small plugin and added to wordpress.

Here is the important part of the code :

//requirements curl
    $user_info = get_userdata($user_id);
    $username = $user_info->user_login;
    $first_name = $user_info->first_name;
    $last_name = $user_info->last_name;
    $leadname = $first_name . ' ' . $last_name;
    if ($leadname == ' ') {
        $leadname = $user_info->user_nicename;
    }
   $email = $user_info->user_email;
   $website = $user_info->user_url; /*It's not working*/
   $user_phone = get_user_meta( $current_user->ID, 'billing_phone'); /*It's not working*/
   $phone = get_user_meta($user_id,'billing_phone');/*It's not working*/
   $phone2 = $user_info->billing_phone;/*It's not working*/
   $store_name = $user_info->store_name;/*It's not working*/

   $leadsgroup = $options['crm_input_field_2'];
    
    /* Do the magic - execute cURL */
    curl_setopt($ch, CURLOPT_URL, $posturl);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_POST, 1);
    curl_setopt($ch, CURLOPT_POSTFIELDS, "source=$leadsgroup&status=1&name=$leadname&website=$website&email=$email&phone=$phone&company=$store_name");
    $headers = array();
    $headers[] = 'Authtoken: ' . $apikey;
    $headers[] = 'Content-Type: application/x-www-form-urlencoded';
    curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);

/*Save result for logging purposes */
$result = curl_exec($ch);
file_put_contents($dir . ‘lastoutput.txt’, $result);

——end code——-
I could get information for name, family and email.
The questions are :
1- How can i get information for these field when vendors register on the site . Phone, address, zip code, store name and store url, city?
2- I made some custom field to get vendors whatsapp on vendor regestration page using WCFM -> setting -> custom fields
How can i get custom field information ?

Thank you very much for your help!
