Запросы Python: вход в Paytm для очистки данных продавца

Я пытаюсь использовать библиотеку запросов python для входа в paytm и царапать данных продавцов paytm со своего веб-сайта, используя Paytm поблизости. Но я не могу это сделать, у меня много вопросов, например, нужно ли мне входить в систему или файлы cookie делают эту работу за меня, нужно ли мне помещать запрос на получение перед запросом на публикацию.

Код, который я использовал

payload = {"distance":10,"endLimit":20,"latitude":26.8467088,"longitude":80.9461592,
       "searchFilter":[{"filterType":"SERVICE","value":"PAYMENT_POINT"}],
       "sortBy":{"DISTANCE_WISE_SORT":"ASC"},"startLimit":20,"channel":"web","version":2}
pp = {"method":"get","channel":"web","version":2}
h = {'Content-type': 'application/json', 'Accept': 'application/json, text/plain, */*',
    'User-Agent': 'Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/70.0.3538.77 Safari/537.36'
,'Accept-Encoding': 'gzip, deflate, br','Accept-Language': 'en-US,en;q=0.9','Connection': 'keep-alive'
         #,'Content-Length': '222'
}

url = 'https://paytm.com/v1/api/getnearbysellers?child_site_id=1&site_id=1'

initial_url = 'https://paytm.com/nearby'

with requests.Session() as session:
    initial_response  = session.get(initial_url)

    response = session.post(url, headers=h, data=payload)


response.text

Ответ я получил-

{"error":"invalid json","code":400}

То, что я получил с помощью инструмента мониторинга сети в Chrome
