"title": "InvoiceEvent",
                        "required": ["description", "paid"],
                        "type": "object",

Это могут быть буквально одна-две строки кода, например:

```Python
callback_url = "https://example.com/api/v1/invoices/events/"
httpx.post(callback_url, json={"description": "Invoice paid", "paid": True})
```

Es könnten nur eine oder zwei Codezeilen sein, wie zum Beispiel:

```Python
callback_url = "https://example.com/api/v1/invoices/events/"
httpx.post(callback_url, json={"description": "Invoice paid", "paid": True})
```

                                                       items="${labelTypeItems}">
                                            <c:forEach var="ltid" varStatus="s"
                                                       items="${labelTypeIds}">
                                                <c:if test="${ltid==l.id}">
                                                    ${f:h(l.name)}<br/>
                                                </c:if>

                                                       items="${labelTypeItems}">
                                                <c:forEach var="ltid" varStatus="s"
                                                           items="${labelTypeIds}">
                                                    <c:if test="${ltid==l.id}">
                                                        ${f:h(l.name)}<br/>
                                                    </c:if>

                                                </c:if>

It could be just one or two lines of code, like:

```Python
callback_url = "https://example.com/api/v1/invoices/events/"
httpx.post(callback_url, json={"description": "Invoice paid", "paid": True})
```
