Hi I am quite new to WC1. I have the API key and the API secret. I am trying to use python to connect to WC1 API and automate a few things. I need some help with the authorization value in the header.

I am trying to execute the below snipprt.

import requests

url = "https://api-worldcheck.refinitiv.com/v2/reference/countries"

headers = {
    "Authorization": "SOME_STRING_VALUE",
    "Date": "SOME_STRING_VALUE"
}

response = requests.request("GET", url, headers=headers)

print(response.text

I have come to learn the authorization value should be something like the below.

Signature keyId="xxxxxxxxxxxxx",algorithm="hmac-sha256",
   headers="(request-target) host date content-type content-length",
   signature="xxxxxxxxxxxxxxxxxxxxxxxxxxxxx"

Can anyone please guide me in the correct way on how to generate the signature?

I am aware that the signature should be generated using HMAC but the official documentation is not entirely clear on what data to use as input.

Host: api-worldcheck.refinitiv.com
Date: Tue, 07 Jun 2016 20:51:35 GMT
Content-Type: application/json
Content-Length: 88
Authorization: Signature keyId="4321",algorithm="hmac-sha256",
   headers="(request-target) host date content-type content-length",
   signature="Iktz/AdXHmDouNm6uBB8ZW0xcfNGuWGDxmX9TFMwuF0="

{
  "caseId": "my customer ID",
  "name": "John Doe",
  "providerTypes": ["WATCHLIST"]
}

For instance, is it essential to have the caseID, name and providerTypes when generating the signature? If yes, what are these values pointing to? I am just looking to connect to WC1 and have some articles resolved using python.

Thanks in advance.
