+# Приложение предоставления API и логики формирования и отправки QR-кодов
+
+Приложение предоставляет API для получения QR-кодов для дверей по идентификатору устройства, получение слотов для дверей по идентификатору партнера.
+Реализует логику формирования и отправки QR-кодов, интеграцию с платежным шлюзом методом обратного вызова и методом опроса REST метода шлюза.
+
+## Запуск приложения
+
+Для приложения требуется БД и конфигурация подключения к БД.
+При запуске приложения будут выполнены миграции в src/main/resources/db/changelog
+Также для работы приложения нужен запущенный сервер авторизации
+
+Для запуска приложения нужно выполнить команду 
+
+`gradle bootRun`
+
+## Сборка приложения
+
+`gradle jar`
+
+## Задания по расписанию
+
+- EmailOutboxSendJob - задание формирования и отправки QR-кода
+- CleanExpiredNotPayedRentJob - задание по расписанию для опроса платежного шлюза и удаления просроченных не оплаченных бронирований
+
+## Http методы
+
+- POST /public/book - метод бронирования двери
+- POST /public/book/callback - метод для обратного вызова шлюза
+- GET /qr - метод получения QR-кодов для определенного устройства(информация об устройстве берется из токена)
+- POST /qr-used/{qrId} - метод пометки о том, что qr-код был использован(для сбора метрик)
+- GET /public/slots/{partnerId} - метод получения текущего расписания дверей для партнера
