[Python] ClassMarker API Integration

I am trying to use the ClassMarker API on my website, but I keep getting an apiKeyAuthFail error; the documentation mentions this:

$your_api_key = 'd4tsE7SvEgzAKlJPFrlvAz3oe9uFQnxy';
$your_api_secret = 'keepThisSecret';
$current_unix_timestamp = time();
$signature = md5($your_api_key . $your_api_secret . $current_unix_timestamp);


This is what im doing in python:

def prepare_classmarker_request(apikey, apisecret):
timestamp = str(int(time.time()))
signature = hashlib.md5(f"{apikey}{apisecret}{timestamp}".encode()).hexdigest()
return signature, timestamp


This is an example they have in their documentation:

https://api.classmarker.com/v1.json?api_key=XXXX&signature=XXXX&timestamp=XXXX


This is how im trying to consume it:

@app.route('/test-auth', methods=['POST','GET'])
def test_auth():
signature, timestamp = prepare_classmarker_request(API_KEY, API_SECRET)

url = f"https://api.classmarker.com/v1.json?apikey={API_KEY}&signature={signature}&timestamp={timestamp}"

response = requests.get(url)

if response.status_code == 200:
tests = response.json()
return jsonify(tests)
else:
return jsonify({
"message": "Failed to authenticate",
"status": response.status_code,
"response": response.json()
})


There are not a lot of examples in their website or at least I dint find many... https://www.classmarker.com/docs/ClassMarker-Integration.pdf

What am I trying to accomplish?

I am building a website for the user to create quizzes and have the results delivered instantly: speaking, written (grammar), reading and listening. I am looking for APIs or services that can help me with this to avoid building everything from scratch.
