Я следил за интеграционными документами paypal https://developer.paypal.com/docs/checkout/reference/server-integration/set-up-transaction/

Проблема: я получил эту ошибку «Неперехваченная ошибка: Ожидалось, что идентификатор заказа будет передан по адресу https://www.sandbox.paypal.com/smart/buttons?style.компоновка=вертикальная»
