### AUTHPARAMS

Indicates STS API Authorization information. If you are familiar with AWS Signature V4 Authorization header, this STS API supports signature V4 authorization as mentioned [here](https://docs.aws.amazon.com/general/latest/gr/signature-version-4.html)

### DurationSeconds

It is based on <a href="https://www.python-httpx.org" class="external-link" target="_blank">HTTPX</a>, which in turn is designed based on Requests, so it's very familiar and intuitive.

With it, you can use <a href="https://docs.pytest.org/" class="external-link" target="_blank">pytest</a> directly with **FastAPI**.

## Using `TestClient`

/// info

Ele é baseado no <a href="https://www.python-httpx.org" class="external-link" target="_blank">HTTPX</a>, que por sua vez é projetado com base em Requests, por isso é muito familiar e intuitivo.

Com ele, você pode usar o <a href="https://docs.pytest.org/" class="external-link" target="_blank">pytest</a> diretamente com **FastAPI**.

## Usando `TestClient`

/// info | "Informação"

It will have a *path operation* that will receive an `Invoice` body, and a query parameter `callback_url` that will contain the URL for the callback.

This part is pretty normal, most of the code is probably already familiar to you:

```Python hl_lines="9-13  36-53"
{!../../docs_src/openapi_callbacks/tutorial001.py!}
```

/// tip

Ele terá uma *operação de rota* que receberá um corpo `Invoice`, e um parâmetro de consulta `callback_url` que conterá a URL para o callback.

Essa parte é bastante normal, a maior parte do código provavelmente já é familiar para você:

```Python hl_lines="9-13  36-53"
{!../../docs_src/openapi_callbacks/tutorial001.py!}
```

/// tip | Dica

}

func forEachInpodMarkIPRule(cfg *Config, f func(*netlink.Rule) error) error {
	var rules []*netlink.Rule
	families := []int{unix.AF_INET}
	if cfg.EnableIPv6 {
		families = append(families, unix.AF_INET6)
	}
	for _, family := range families {
		// Equiv:
		// ip rule add fwmark 0x111/0xfff pref 32764 lookup 100
		//
		// Adds in-pod rules for marking packets with the istio-specific TPROXY mark.

Isto pode facilitar bastante para os seus usuários **implementarem as APIs deles** para receber as requisições dos seus **webhooks**, eles podem inclusive ser capazes de gerar parte do código da API deles.

/// info | "Informação"

With fast fallback, OkHttp attempts to connect to multiple web servers concurrently. It keeps whichever route connects first and cancels all of the others. Its rules are:

 * Prefer to alternate IP addresses from different address families, (IPv6 / IPv4), starting with IPv6.
 * Don't start a new attempt until 250 ms after the most recent attempt was started.
 * Keep whichever TCP connection succeeds first and cancel all the others.
