How to activate Kuna Code via API?

Question

Python

The essence of the problem is that through the api I am trying to activate the so-called Kuna Code, which activates the translation,

import requests
import time
import hmac
import hashlib

secret_key = '' # здесь все указываем
public_key = '' # здесь все указываем

url = "https://api.kuna.io/v3/auth/kuna_codes/redeem"
api_path = "/v3/auth/kuna_codes/redeem"

rs = 'https://api.kuna.io/v3/auth/me'    
api_paths = "/v3/auth/me"

body = ''
nonce = str(int(time.time()*1000.0)) 
body = str('')
msg = api_paths+nonce+body
print(msg)
kun_signature = hmac.new(secret_key.encode('ascii'), msg.encode('ascii'), hashlib.sha384).hexdigest()

headers = {
    "Accept": "application/json",
    "Content-Type": "application/json",
    'kun-nonce': nonce,
    'kun-apikey': public_key,
    'kun-signature': kun_signature
}

pool = requests.post(rs, headers=headers)
print(pool.text)
codein = {"code": ""}
response = requests.request("PUT", url, json=codein, headers=headers) #активация кода
print(response.text)

Authorization is successful and data with email and other data is displayed, but after that
an error like

{"messages":["the_tonce_has_already_been_used_by_access_key"]}

What am I doing wrong? I also tried to change the headers to different ones, and in this case an error like signature_is_incorrect gets out, all to no avail. That is, authorization is successful, and the second request throws an error
