## Documenting the callback { #documenting-the-callback }

The actual callback code will depend heavily on your own API app.

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})
```

     * @param pbCall callback to configure the ProcessBuilder
     * @param bufferSize size of the buffer for process output
     * @param outputCallback callback to handle process output lines
     * @return JobProcess representing the started process
     * @throws JobProcessingException if the process cannot be started
