How to take a reserve from a product via API?

Question

1C-Bitrix

Good afternoon!
The item is placed into the reserve using standard Bitrix tools.
How can I remove it from the reserve through the API?
There is a link but it didn't work for me. I don't understand how to use \Bitrix\Catalog\Product\CatalogProvider

Answer 1

Wow what did it cost
me

//резервирование товара
$productId = 12;

$a = new \Bitrix\Catalog\Product\CatalogProvider;
$resReserve = $a->reserve(array(
    $productId => ["PRODUCT_ID" => $productId,  "QUANTITY" => 15]
));

//снятие резерва
//для снятия резерва ВАЖНО чтобы QUANTITY был ОТРИЦАТЕЛЬНЫЙ 

$a = new \Bitrix\Catalog\Product\CatalogProvider;
$resReserve = $a->reserve(array(
    $productId => ["PRODUCT_ID" => $productId,  "QUANTITY" => -15 ]
));

Answer 2

The method by reference is not about that, it simply returns information, but it must be changed. https://dev.1c-bitrix.ru/api_help/catalog/classes/... is more suitable here
instead
of CCatalogProductProvider::ReserveProduct($arParams);
Use
\Bitrix\Catalog\Product\CatalogProvider::ReserveProduct($arParams);
