I can't submit information on a page

Question

Faced a problem. Can't get data after post request. A blank page comes up. When I do the same thing on the site everything is ok.

import requests
url = "https://tools.usps.com/zip-code-lookup.htm?byaddress"

payload = {'tCompany': 'CARDIOSTART RESALE THRIFT STR', 'tAddress': '435 W CASCADE AVE', 'tCity': 'SISTERS','tState': 'OR', 'tZip-byaddress': '97759'}

    r = requests.post(url, payload, allow_redirects=False, headers=HEADERS)
with open("requests_results.html", "wb") as f:
    f.write(r.content)


    print(r.status_code)
