Служба доставки Amazon MWS, отвечающая требованиям доставки, возвращает недоступных перевозчиков

Question

Я пытаюсь получить список операторов, использующих MWS scratchpad api. Api раздел Выполнение Merchanf -> Получите соответствующие услуги доставки. Мой пост выглядит так. Это то же самое, что и в документации. Все необходимые детали есть.
