And it will probably vary a lot from one app to the next.

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})
```

If you are using a third party library that communicates with something (a database, an API, the file system, etc.) and doesn't have support for using `await`, (this is currently the case for most database libraries), then declare your *path operation functions* as normally, with just `def`, like:

```Python hl_lines="2"
@app.get('/')
def results():
    results = some_library()
    return results
```

            ),
          )
        assertContent("B", response)
        break
      } catch (socketException: IOException) {
        // If there's a socket exception, this must have a streamed request body.
        assertThat(j).isEqualTo(0)
        assertThat(transferKind).isIn(TransferKind.CHUNKED, TransferKind.FIXED_LENGTH)
      }
    }
    val requestA = server.takeRequest()

It's all based on standard **Python type** declarations (thanks to Pydantic). No new syntax to learn. Just standard modern Python.
