Необходимо узнать адрес уведомления о входящих платежах или переводах на адрес сервера?

меня интересует часть текста после ?wc-api=
Я так понимаю именно после правильного заполнения данной формы статус моего заказа будет автоматически переводиться в Выполнен.

Так же я посмотрел в интернете ролик где говорят, что нужно ввести WP_yandexmoney и еще много различных комбинаций видел но не одна не подошла. я так подозреваю это от плагина зависит.
Ниже прилагаю часть кода если она поможет:
Буду благодарен если подскажете как довести до ума все это))
