## Escrevendo o código de documentação do callback

Esse código não será executado em seu aplicativo, nós só precisamos dele para *documentar* como essa *API externa* deveria ser.

Mas, você já sabe como criar facilmente documentação automática para uma API com o **FastAPI**.

# İlk Adımlar

En sade FastAPI dosyası şu şekilde görünür:

{* ../../docs_src/first_steps/tutorial001.py *}

Yukarıdaki içeriği bir `main.py` dosyasına kopyalayalım.

Uygulamayı çalıştıralım:

<div class="termy">

```console
$ uvicorn main:app --reload

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
<span style="color: green;">INFO</span>:     Started reloader process [28720]

			// Expect header is always of form:
			//
			//   Expect       =  "Expect" ":" 1#expectation
			//   expectation  =  "100-continue" | expectation-extension
			//
			// So it safe to assume that '100-continue' is what would
			// be sent, for the time being keep this work around.
			// Adding a *TODO* to remove this later when Golang server
			// doesn't filter out the 'Expect' header.
