This would mean that **FastAPI** would expect a body similar to:

```JSON
{
    "name": "Foo",
    "description": "The pretender",
    "price": 42.0,
    "tax": 3.2,
    "tags": ["rock", "metal", "bar"],
    "image": {
        "url": "http://example.com/baz.jpg",
        "name": "The Foo live"
    }
}
```

	istioInjectionWebhookSuffix = "sidecar-injector.istio.io"

	vwhBaseTemplateName = "istiod-default-validator"

	operatorNamespace = "operator.istio.io"
)

// tagWebhookConfig holds config needed to render a tag webhook.
type tagWebhookConfig struct {
	Tag            string
	Revision       string
	URL            string
	Path           string
	CABundle       string
	IstioNamespace string

Todo **FastAPI** está basado en estos type hints, lo que le da muchas ventajas y beneficios.

Pero, así nunca uses **FastAPI** te beneficiarás de aprender un poco sobre los type hints.

    Si eres un experto en Python y ya lo sabes todo sobre los type hints, salta al siguiente capítulo.

## Motivación

Comencemos con un ejemplo simple:

      You can check the list of the approved counters and their current configuration in [config.txt](https://go.googlesource.com/telemetry/+/master/internal/configgen/config.txt).
    render: Text
    value: |
      counter: gopls/bug
      title: Gopls bug reports
      description: Stacks of bugs encountered on the gopls server.
      type: partition, histogram, stack # choose only one.

    validations:
      required: true
  - type: textarea
    id: go-env
    attributes:
      label: "Output of `go env` in your module/workspace:"
      render: shell
    validations:
      required: true
  - type: textarea
    id: what-did-you-do
    attributes:
      label: "What did you do?"
