Установка стандартная, конфиг нужно скопировать из .env.example в .env, поправив доступы к БД.
API работает полностью на JSON и с соблюдением стандартных соглашений о путях и REST.
Запросы идут на /api/poster для списка, POST туда же для создания и DELETE по пути /api/poster/1 для удаления.
Для запуска локального сервера нужно накатить миграции php artisan migrate и запустить сервер php artisan serve
Для проверки можно использовать следующий конфиг Thunder Client (должен подойти и для Postman)
