# Настройка Swagger UI { #configure-swagger-ui }

Вы можете настроить дополнительные <a href="https://swagger.io/docs/open-source-tools/swagger-ui/usage/configuration/" class="external-link" target="_blank">параметры Swagger UI</a>.

Чтобы настроить их, передайте аргумент `swagger_ui_parameters` при создании объекта приложения `FastAPI()` или в функцию `get_swagger_ui_html()`.
