+#### Новая сделка (ордер)
+
+Ордер создается без указания адреса платежа (поле `payment`). Адрес платежа связан с исходными данными ордера. Зная исходные данные ордера можно вычислить адрес платежа.

+Адрес платежа создается модулем сделок. 
+
+**Пример:**
+
+Минимально необходимый набор данных для создания ордера (в формате JSON) предоставлен ниже:
+
+Запрос:
+
+~~~http request
+POST /api/v1/deal
