## 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/"

### Kendi Kullanıcı Verinizi Alma { #get-your-own-user-data }

Şimdi `/users/me` path’inde `GET` operasyonunu kullanın.

Kullanıcınızın verisini şöyle alırsınız:

```JSON
{
  "username": "johndoe",
  "email": "******@****.***",

    return isRunning ? ticker.read() - startTick + elapsedNanos : elapsedNanos;
  }

  /**
   * Returns the current elapsed time shown on this stopwatch, expressed in the desired time unit,
   * with any fraction rounded down.
   *
   * <p><b>Note:</b> the overhead of measurement can be more than a microsecond, so it is generally
   * not useful to specify {@link TimeUnit#NANOSECONDS} precision here.
