# OpenAPI'yi Genişletme { #extending-openapi }

Oluşturulan OpenAPI şemasını değiştirmeniz gereken bazı durumlar olabilir.

Bu bölümde bunun nasıl yapılacağını göreceksiniz.

## Normal Süreç { #the-normal-process }

Normal (varsayılan) süreç şöyledir.

Bir `FastAPI` uygulamasının (instance) OpenAPI şemasını döndürmesi beklenen bir `.openapi()` metodu vardır.

## Security - HTTPS { #security-https }

In the [previous chapter about HTTPS](https.md) we learned about how HTTPS provides encryption for your API.

We also saw that HTTPS is normally provided by a component **external** to your application server, a **TLS Termination Proxy**.

## About "Form Fields" { #about-form-fields }

The way HTML forms (`<form></form>`) sends the data to the server normally uses a "special" encoding for that data, it's different from JSON.

**FastAPI** will make sure to read that data from the right place instead of JSON.

/// note | Technical Details

Data from forms is normally encoded using the "media type" `application/x-www-form-urlencoded`.
