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
```

с телом JSON примерно такого вида:

```JSON
{

Por ejemplo, el modelo anterior declara un “`object`” JSON (o `dict` en Python) como:

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

...dado que `description` y `tax` son opcionales (con un valor por defecto de `None`), este “`object`” JSON también sería válido:

```JSON
{
    "name": "Foo",
    "price": 45.2
}
```

### Поле `examples` в JSON Schema { #json-schemas-examples-field }

Позже в новой версии спецификации JSON Schema было добавлено поле <a href="https://json-schema.org/draft/2019-09/json-schema-validation.html#rfc.section.9.5" class="external-link" target="_blank">`examples`</a>.

А затем новый OpenAPI 3.1.0 был основан на последней версии (JSON Schema 2020-12), которая включала это новое поле `examples`.

import json
from pathlib import Path

file_path = Path("./openapi.json")
openapi_content = json.loads(file_path.read_text())

for path_data in openapi_content["paths"].values():
    for operation in path_data.values():
        tag = operation["tags"][0]
        operation_id = operation["operationId"]
        to_remove = f"{tag}-"
        new_operation_id = operation_id[len(to_remove) :]
        operation["operationId"] = new_operation_id

		AES256GCM        = "AES-256-GCM-HMAC-SHA-256"

		Nonce     []byte `json:"nonce"`
		Bytes     []byte `json:"bytes"`
	}
	var value JSON
	if err := json.Unmarshal(text, &value); err != nil {

### `UJSONResponse`

<a href="https://github.com/ultrajson/ultrajson" class="external-link" target="_blank">`ujson`</a>을 사용한 또 다른 JSON 응답 형식입니다.

/// info | 정보

이 응답을 사용하려면 `ujson`을 설치해야합니다. 예: 'pip install ujson`.

///

/// warning | 경고

`ujson` 은 일부 예외 경우를 처리하는 데 있어 Python 내장 구현보다 덜 엄격합니다.
