* Передаёте JSON в теле запроса, передав Python-объект (например: `dict`) через именованный параметр `json`.
* Если же Вам необходимо отправить *форму с данными* вместо JSON, то используйте параметр `data` вместо `json`.
* Для передачи *заголовков*, передайте объект `dict` через параметр `headers`.
* Для передачи *cookies* также передайте `dict`, но через параметр `cookies`.
