# Extendendo o OpenAPI

Existem alguns casos em que pode ser necessário modificar o esquema OpenAPI gerado.

Nesta seção, você verá como fazer isso.

## O processo normal

O processo normal (padrão) é o seguinte:

Uma aplicação (instância) do `FastAPI` possui um método `.openapi()` que deve retornar o esquema OpenAPI.

Isso significa que no lugar do processo normal de seus usuários enviarem requisições para a sua API, é a **sua API** (ou sua aplicação) que poderia **enviar requisições para o sistema deles** (para a API deles, a aplicação deles).

Isso normalmente é chamado de **webhook**.
