To enable the integration of custom authentication methods, MinIO can be configured with an Identity Management Plugin webhook. When configured, this plugin enables the `AssumeRoleWithCustomToken` STS API extension. A user or application can now present a token to the `AssumeRoleWithCustomToken` API, and MinIO verifies this token by sending it to the Identity Management Plugin webhook. This plugin responds with some information and MinIO is able to generate temporary STS credentials to interact...

The example above shows all the parts you need, but it's not very useful yet, as you could have just returned the `item` directly, and **FastAPI** would put it in a `JSONResponse` for you, converting it to a `dict`, etc. All that by default.

Now, let's see how you could use that to return a custom response.

Let's say that you want to return an [XML](https://en.wikipedia.org/wiki/XML) response.

`config.json` and bucket DNS SRV records. `MINIO_DOMAIN` indicates the domain suffix for the bucket which
will be used to resolve bucket through DNS. For example if you have a bucket such as `mybucket`, the
client can use now `mybucket.domain.com` to directly resolve itself to the right cluster. `MINIO_PUBLIC_IPS`
points to the public IP address where each cluster might be accessible, this is unique for each cluster.

  // Technically we should test other reentrant scenarios (9 combinations of
  // hasNext/next/peek), but we'll cop out for now, knowing that peek() and
  // next() both start by invoking hasNext() anyway.
