How to fix Python 400 'Bad Request' error with post requests?

I am unable to get the response of my post request. It gives me 400 error. while in postman, it works fine.

The code is below

import requests
from urllib3.exceptions import InsecureRequestWarning

url = ""

payload = """[{{\n  \"dateOfBirth\": \"{}\",\n  \"nationalIdentityNo\": \"{}\"\n}}]"""

headers = {
    'x-req-id': "89567890987610",
    'x-channel-id': "MB",
    'x-sub-channel-id': "MB",
    'x-country-code': "PK",
    'x-customer-type': "C",
    'Authorization': "Bearer eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJrZXkiOiJhZGlsIn0.mRSZXF0glqRPyo2h15jHd51JwCeEnSUIBmYuTaAzmrQ",
    'accept': "application/json",
    'Content-Type': "application/json",
    'User-Agent': "PostmanRuntime/7.19.0",
    'Cache-Control': "no-cache",
    'Postman-Token': "566b2e63-9320-4a59-9524-f480f33fd62f,f7ba71fd-503a-451c-8817-2198f09c1d0c",
    'Host': "*********",
    'Accept-Encoding': "gzip, deflate",
    'Content-Length': "75",
    'Connection': "keep-alive",
    'cache-control': "no-cache"
}

requests.packages.urllib3.disable_warnings(category=InsecureRequestWarning)
response = requests.request("POST", url, data=payload.format(new_date, IDNO), headers=headers, verify=False)
print(response.status_code)
print(response.text)

This is result I am getting.

400

Your headers JSON is incorrect. The key has single quotes. Correct JSON requires "key":"value" in double quotes, unless a value is an integer! Try changing all quotes to double quotes in your header.

Also your payload is quite confusing

payload = """[{{\n \"dateOfBirth\": \"{}\",\n \"nationalIdentityNo\": \"{}\"\n}}]"""

Just make this in your response directly data='{{"dateOfbirth": {},"nationalIdentityNo": {}}}'.format(new_date, IDNO)

https://www.w3schools.com/python/ref_requests_post.asp

url = "string"
payload = [{'key':'value'},]  # a JSON object
headers = {'key':'value'}  # a dictionary
response = requests.post(url, data=payload, headers=headers)

Did you try this, instead of using a stringified JSON object as payload?
