There are some cases where you might need to convert a data type (like a Pydantic model) to something compatible with JSON (like a `dict`, `list`, etc).

For example, if you need to store it in a database.

For that, **FastAPI** provides a `jsonable_encoder()` function.

## Using the `jsonable_encoder` { #using-the-jsonable-encoder }

Let's imagine that you have a database `fake_db` that only receives JSON compatible data.

## Introduction

To integrate with custom authentication methods using the [Identity Management Plugin](../iam/identity-management-plugin.md)), MinIO provides an STS API extension called `AssumeRoleWithCustomToken`.

After configuring the plugin, use the generated Role ARN with `AssumeRoleWithCustomToken` to get temporary credentials to access object storage.

You could also use `from starlette.requests import Request`.

**FastAPI** provides it directly just as a convenience for you, the developer. But it comes directly from Starlette.
