Portanto, o navegador irá enviar uma requisição HTTP `OPTIONS` ao backend, e se o backend enviar os cabeçalhos apropriados autorizando a comunicação a partir de uma origem diferente (`http://localhost:8080`) então o navegador deixará o JavaScript no frontend enviar sua requisição para o backend.

Para conseguir isso, o backend deve ter uma lista de "origens permitidas".

Adoptar temporalmente este punto de vista (del *desarrollador externo*) puede ayudarte a sentir que es más obvio dónde poner los parámetros, el modelo de Pydantic para el body, para el response, etc. para esa *API externa*.

## Geradores de Clientes OpenAPI

Existem muitas ferramentas para gerar clientes a partir do **OpenAPI**.

Uma ferramenta comum é o <a href="https://openapi-generator.tech/" class="external-link" target="_blank">OpenAPI Generator</a>.
