# Additional Responses in OpenAPI { #additional-responses-in-openapi }

/// warning

This is a rather advanced topic.

If you are starting with **FastAPI**, you might not need this.

///

You can declare additional responses, with additional status codes, media types, descriptions, etc.

Those additional responses will be included in the OpenAPI schema, so they will also appear in the API docs.

要在开发环境中运行你的 FastAPI 应用，可以使用 `fastapi dev` 命令：
