## OpenAPI and API docs

If you return additional status codes and responses directly, they won't be included in the OpenAPI schema (the API docs), because FastAPI doesn't have a way to know beforehand what you are going to return.

  @Synchronized
  override fun onResponse(
    call: Call,
    response: Response,
  ) {
    val body = response.body.string()
    responses.add(RecordedResponse(call.request(), response, null, body, null))
    (this as Object).notifyAll()
  }

  /**
   * Returns the recorded response triggered by `request`. Throws if the response isn't
   * enqueued before the timeout.

!!! note "Detalles Técnicos"
    También puedes usar `from starlette.responses import JSONResponse`.

It will:

* Return that status code in the response.
* Document it as such in the OpenAPI schema (and so, in the user interfaces):

!!! note
    Some response codes (see the next section) indicate that the response does not have a body.

    FastAPI knows this, and will produce OpenAPI docs that state there is no response body.

## About HTTP status codes

!!! note

    * Ein spezieller Fall ist `204`, „No Content“ („Kein Inhalt“). Diese Response wird verwendet, wenn es keinen Inhalt gibt, der zum Client zurückgeschickt wird, diese Response hat also keinen Body.
* **`300`** und darüber steht für „Redirection“ („Umleitung“).  Responses mit diesen Statuscodes können einen oder keinen Body haben, mit Ausnahme von `304`, „Not Modified“ („Nicht verändert“), welche keinen haben darf.
