PayPal Chained Payment (деньги не идут на второй счет)

Я совершаю связанный платеж PayPal. Я продаю билеты для клиентов и удерживаю плату в размере стоимости электронного билета (ов). Сейчас тестирую в режиме песочницы, и деньги идут на первичку, а не на вторичку. Я использую php-скрипт suberb от angelleye.

Вот массив платежей, в основной учетной записи я даже настроил «API-доступ» к «paypal-facilitator_api1.wetickets.nl» (я не знаю, нужно ли это) ... Что я упускаю? Спасибо за помощь!
