How to create a signature in python using an api key and timestamp, with sha256 hex encryption

Question

This is the sample code provided within the api documentation:

#!/bin/bash 
apiKey="yourApiKey"
secret="yourSecret"
curl -i \
-X GET \
-H 'Accept:application/json' \
-H 'Api-key:'$apiKey'' \
-H 'X-Signature:'$(echo -n ${apiKey}${secret}$(date +%s)|sha256sum|awk '{ print $1}')'' \
https://api.test.hotelbeds.com/hotel-api/1.0/status

This is what I am doing in python:

secret = b"Secret key"
apikey = b"Api key"
datenow = str(datetime.datetime.now().timestamp())
datenow = bytes(datenow, 'utf-8')

sig = apikey + secret + datenow

hash = hashlib.sha256(sig).hexdigest()

However, I am getting an authentication error. Can someone please help me fix my code?

Just use strings instead of bytes?

Problem was solved by converting the date into and int and then into str.

import hashlib, time

string= str(API_KEY).strip()+str(SECRET).strip()+str(int(time.time())).strip()

signature= hashlib.sha256(string.encode()).hexdigest()
