Простое добавление контакта

Пример размещения на странице сайта формы по заполнению которой в Битрикс24 создаётся новый контакт.

1. Создаём форму на нужной странице:

   <form id="form_to_crm">
   	<input type="text" name="NAME" placeholder="Name" required>
   	<input type="text" name="LAST_NAME" placeholder="Last name">
   	<input type="text" name="EMAIL" placeholder="E-mail">
   	<input type="text" name="PHONE" placeholder="Phone">
   	<input type="submit" value="Submit">
   </form>
   <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
   <script>
   	$(document).ready(function() {
   		$('#form_to_crm').on( 'submit', function(el) {//event submit form
   			el.preventDefault();//the default action of the event will not be triggered
   			var formData = $(this).serialize();
   			$.ajax({
   				'method': 'POST',
   				'dataType': 'json',
   				'url': 'form.php',
   				'data':  formData,
   				success: function(data){//success callback
   					alert(data.message);
   				}
   			});
   		});
   	});
   </script>

2. Создаём файл form.php, для сохранения заполненных форм:

   <?			
   $sName = htmlspecialchars($_POST["NAME"]);
   $sLastName = htmlspecialchars($_POST["LAST_NAME"]);
   $sPhone = htmlspecialchars($_POST["PHONE"]);
   $sEmail = htmlspecialchars($_POST["EMAIL"]);				
   
   $arPhone = (!empty($sPhone)) ? array(array('VALUE' => $sPhone, 'VALUE_TYPE' => 'WORK')) : array();
   $arEmail = (!empty($sEmail)) ? array(array('VALUE' => $sEmail, 'VALUE_TYPE' => 'HOME')) : array();
   
   $result = CRest::call(
   	'crm.contact.add',
   	[
   		'fields' =>[
   			'NAME' => $sName,//*First name[string]
