Создание заявок на кредит в Финсервис

После оформления заказа на сайте, необходимо оформить кредит через Финсервис на платформе Poslogic. Согласно предоставленой от Финсервиcа инструкции, был создан обработчик заказов на minishop2.

Согласно документации к minishop2 создаем свой обработчик платежей. В системе minishop2 создадим способ оплаты - Оформить кредит. На него повесим свой обработчик - CreditPayment, заранее его зарегистрировав в minishop2. core/components/minishop2/custom/payment/creditpayment.class.php

Так же необходимо прописать Пространство имен в MODX

И создать системные настройки, в которые в дальнейшем прописываем параметры подключения к Финсервису.

Создаем страницу куда будет перенаправляться после заполнения Анкеты на кредит. И в на эту страницу вешаем скрипт для изминения статуса Заказа. Статус создаем в настройка minishop2 и прописываем в настройках обработчика.
