Why is the price not added at checkout?

Question

1C-Bitrix

There is an example of placing an order via API on the Bitrix

website. I apply it by substituting my data, everything is recorded except for the price, it goes 0.
$order->getPrice()Does not find the right price. From the form, when I insert $request['ELEMENT_PRICE']it, it also does not write, (it writes in the comments, but not in the order). There are no errors in the console. In the admin panel, too, everything is 0

<? require($_SERVER["DOCUMENT_ROOT"] . "/bitrix/modules/main/include/prolog_before.php");

use Bitrix\Main\Application;

$application = Application::getInstance();
$context = $application->getContext();
global $APPLICATION;
global $USER;

$request = \Bitrix\Main\HttpApplication::getInstance()->getContext()->getRequest();

\Bitrix\Main\Web\Json::encode($request);

if ($request->isPost() && isset($request['ELEMENT_ID']) && isset($request['PHONE']) && isset($request['EMAIL']) && isset($request['ELEMENT_PRICE'])) {

Answer 1

So,
if you need a custom product price: the product
array should look like

array(
    'PRODUCT_ID' => 699, 
    'NAME' => 'Товар 1', 
    'PRICE' => 800, 
    'CURRENCY' => 'RUB', 
    'QUANTITY' => 5
    'CUSTOM_PRICE' => 'Y'
)

if you need to pull from a directory:

array(
    'PRODUCT_ID' => 699, 
    'NAME' => 'Товар 1', 
    'CURRENCY' => 'RUB', 
    'QUANTITY' => 5,
    'PRODUCT_PROVIDER_CLASS' => '\CCatalogProductProvider'
)
