## Pydantic `bytes` { #pydantic-bytes }

You can declare a Pydantic model with `bytes` fields, and then use `val_json_bytes` in the model config to tell it to use base64 to *validate* input JSON data, as part of that validation it will decode the base64 string into bytes.

{* ../../docs_src/json_base64_bytes/tutorial001_py310.py ln[1:9,29:35] hl[9] *}

If you check the `/docs`, they will show that the field `data` expects base64 encoded bytes:

But you can also use more complex data types.

And you will still have the same features as seen up to now:

* Great editor support.
* Data conversion from incoming requests.
* Data conversion for response data.
* Data validation.
* Automatic annotation and documentation.

## Other data types { #other-data-types }

Here are some of the additional data types you can use:

* `UUID`:

Birbirleriyle ilişkili bir **cookie** grubunuz varsa, bunları tanımlamak için bir **Pydantic model** oluşturabilirsiniz. 🍪

Bu sayede **model'i yeniden kullanabilir**, **birden fazla yerde** tekrar tekrar kullanabilir ve tüm parametreler için validation ve metadata'yı tek seferde tanımlayabilirsiniz. 😎

/// note | Not

This is supported since FastAPI version `0.115.0`. 🤓
