## Forbid Extra Headers { #forbid-extra-headers }

In some special use cases (probably not very common), you might want to **restrict** the headers that you want to receive.

You can use Pydantic's model configuration to `forbid` any `extra` fields:

{* ../../docs_src/header_param_models/tutorial002_an_py310.py hl[10] *}

If a client tries to send some **extra headers**, they will receive an **error** response.

# Header 1 { #header-1 }

Some text

## Header 2 { #header-2 }

Some more text

### Header 3 { #header-3 }

Even more text

# Header 4 { #header-4 }

A bit more text

#Not a header

Por exemplo, você poderia garantir que cada *operação de rota* tenha uma tag, e então gerar o ID de operação com base na **tag** e no **nome** da *operação de rota* (o nome da função).
