Answer

def create_profile(sender, instance, created, **kwargs):
    if created:
        instance.rooms.room_bool = instance.room_bool
        instance.rooms.save()
        token = '5419477:AAHuyagslasglfsE9O-90vgiDHVTiV2KmqFRNw'
        URL = 'https://api.telegram.org/bot' + token + '/sendMessage'
        for chat_id in ADMINS:
            try:
                data = {'chat_id': chat_id, 'text': "Забронирован один номер через Ресепшенnn"
                                                    "Посмотрите по ссылке http://127.0.0.1:8000/admin/reg_admin/registration/nn"
                                                    "Нажмите /start чтобы вывести меню администратора"}
                requests.post(URL, data=data)
            except Exception:
                pass

using signals.py, I sent a message to the bot via json
