[Python] Timed Hash Verification based web api call in Lindane Scripting Language

I am trying to call a web api which is secred by Timed Hash Verification system.

I am able to call that API using python

import hmac
import hashlib
import time
import requests
import json

def generate_timed_hash(secret_key, data):
timestamp = str(int(time.time())) # Current Unix timestamp
message = data + timestamp
hash_value = hmac.new(secret_key.encode(), message.encode(), hashlib.sha256).hexdigest()
return hash_value, timestamp

def testApi():
data = json.dumps({'userId': 'c088ab7f-dd04-4836-93cd-7ab2843db971'})
secret_key = 'mysecret'
hash_value, timestamp = generate_timed_hash(secret_key, data)

headers = {
'X-Timestamp': timestamp,
'X-Hash': hash_value,
}

response = requests.post('https://some-host/api/secured-plan-detail/', data={'data': data}, headers=headers)
print(response.json())

testApi()


I found llSHA256String for generating SHA256 string. But still not able to figure out way tranaslate that python code.

Here is my attempt to make http call.

default
{
state_entry()
{
llHTTPRequest(
"https://some-host/api/secured-plan-detail/",
[
HTTP_METHOD, "POST",
HTTP_MIMETYPE, "application/json"
//HTTP_CUSTOM_HEADER, "X-Timestamp:", timestamp
//HTTP_CUSTOM_HEADER, "X-Hash:", hash_value
],
llList2Json(JSON_OBJECT, ["userId", "c088ab7f-dd04-4836-93cd-7ab2843db971"])
);
}
http_response(key request_id, integer status, list metadata, string body) {
llOwnerSay((string)status);
llOwnerSay("response: " + body);
}
}


How can make such call in Lindane Scripting Language?
