Простое добавление лида

Пример позволит разместить на любой странице вашего сайта форму, заполняя которую в битрикс24 будет создаваться новый лид.

1. Создаём форму на нужной странице:

   <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>
   	
   <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="PHONE" placeholder="Phone">
   	<input type="text" name="EMAIL" placeholder="E-mail">
   	<input type="submit" value="Submit">
   </form>
   

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"]);
   		
   	//Форматируем телефон и почту для сохранения
   	$arPhone = (!empty($sPhone)) ? array(array('VALUE' => $sPhone, 'VALUE_TYPE' => 'WORK')) : array();
   	$arEmail = (!empty($sEmail)) ? array(array('VALUE' => $sEmail, 'VALUE_TYPE' => 'HOME')) : array();
   
   	$result = CRest::call(
   		'crm.lead.add',
   		[
   		'fields' =>[
