How do I get signature and landed_at data in typeform API?

Question

It used to work like this:

import requests

u = "https://uza3fcl1odf.typeform.com/app/form/result/token/tCsWUtMB/default"
j = requests.post(u, headers={"Accept": "application/json"}).json()
# {'token': '20903331626f396431746f397777693832713331626f39643136747572367978706434313339363936363463366336363533373434333536343134353337366237613339343233303664373236613737353935613431363436393336343833313335333833383332333733393336333333373633653233363637346132653432343938383963326537663165326535633262373837326336613437343539666638653932613131393266386236393635626131353838323739363337', 'landed_at': '1588279637'}

Also here are the topics about this:

• Post request to Typeform failing due to Invalid payload
• Python post request, problem with posting
• error with signature token when filling a typeform
• How to get JSON data from a Python POST request

Here is my test form: https://uza3fcl1odf.typeform.com/to/tCsWUtMB

But now this solution does not work, I do not know why. What kind of POST request should I make to get "signature" and" landed_at " data in response?

It is desirable that your example can be easily checked in Postman.
