Wenn Sie diese Sichtweise (des *externen Entwicklers*) vorübergehend übernehmen, wird es offensichtlicher, wo die Parameter, das Pydantic-Modell für den Body, die Response, usw. für diese *externe API* hingehören.

- Introduction of a new "sync_proxy_rules_no_local_endpoints_total" proxy metric. This metric represents the number of services with no internal endpoints. The "traffic_policy" label will contain both "internal" or "external". ([#108930](https://github.com/kubernetes/kubernetes/pull/108930), [@MaxRenaud](https://github.com/MaxRenaud))

This combination of Flask, Flask-apispec with Marshmallow and Webargs was my favorite backend stack until building **FastAPI**.

Using it led to the creation of several Flask full-stack generators. These are the main stacks I (and several external teams) have been using up to now:

* [https://github.com/tiangolo/full-stack](https://github.com/tiangolo/full-stack)

```
https://yourapi.com/invoices/?callback_url=https://www.external.org/events
```

з JSON-тілом:

```JSON
{
    "id": "2expen51ve",
    "customer": "Mr. Richie Rich",
    "total": "9999"
}
```

тоді *ваш API* опрацює рахунок і згодом надішле запит зворотного виклику на `callback_url` ( *зовнішній API* ):

```
https://www.external.org/events/invoices/2expen51ve
```

```

```

с телом JSON:

```JSON
{
    "id": "2expen51ve",
    "customer": "Mr. Richie Rich",
    "total": "9999"
}
```

то *ваш API* обработает счёт и, в какой-то момент позже, отправит запрос обратного вызова на `callback_url` (*внешний API*):

```
https://www.external.org/events/invoices/2expen51ve
```

El proceso que ocurre cuando tu aplicación API llama a la *API externa* se llama un "callback". Porque el software que escribió el desarrollador externo envía un request a tu API y luego tu API hace un *callback*, enviando un request a una *API externa* (que probablemente fue creada por el mismo desarrollador).
