The same as when declaring query parameters, when a model attribute has a default value, it is not required. Otherwise, it is required. Use `None` to make it just optional.

For example, this model above declares a JSON "`object`" (or Python `dict`) like:

```JSON
{
    "name": "Foo",
    "description": "An optional description",
    "price": 45.2,
    "tax": 3.5

 *
 * <p>Note that usually type mappings are already implied by the static type hierarchy (for example,
 * the {@code E} type variable declared by class {@code List} naturally maps to {@code String} in
 * the context of {@code class MyStringList implements List<String>}). In such case, prefer to use
 * {@link TypeToken#resolveType} since it's simpler and more type safe. This class should only be

- [Configuring etcd](https://github.com/minio/minio/blob/master/docs/sts/etcd.md)

### Setup MinIO with Identity Provider

Make sure we have followed the previous step and configured each software independently, once done we can now proceed to use MinIO STS API and MinIO server to use these credentials to perform object API operations.
