API to put Multiple resource in SDT getting Authentication failed

Thanks Mike for your reply.

Below is the code i am trying to execute.

def generate_signature(http_verb, resource_path, request_body=""):

    timestamp = str(int(time.time() * 1000))  # Current time in milliseconds

    request_vars = http_verb + timestamp + request_body + resource_path

    hmac_digest = hmac.new(ACCESS_KEY.encode(), msg=request_vars.encode(), digestmod=hashlib.sha256).digest()

    signature = base64.b64encode(hmac_digest).decode()

    return signature, timestamp

# Function to get device ID by hostname

def get_device_id(hostname):

    resource_path = f"/device/devices?filter=displayName:{hostname}"

    url = BASE_URL + resource_path

    signature, timestamp = generate_signature("GET", resource_path)

    headers = {

        "Authorization": f"LMv1 {ACCESS_ID}:{signature}:{timestamp}",

        "Content-Type": "application/json"

    }

    print("\n🔍 Debugging Authentication:")

    print(f"🔹 Access ID: {ACCESS_ID}")

    print(f"🔹 Generated Signature: {signature}")

    response = requests.get(url, headers=headers, verify=False)  # Ignore SSL warning

    # 🔹 Debugging: Print the response before parsing

    print(f"\n🔍 Debugging API Response for {hostname}:")

    print(f"🔹 Status Code: {response.status_code}")

    print(f"🔹 Response Text: {response.text}")

    print(f"🔹 Timestamp: {timestamp}")

    # 🔹 Check if API returned success before parsing JSON

    if response.status_code == 200:

        try:

            data = response.json()

            if data is None:

                print(f"❌ API returned None for {hostname}. Possible issue with API.")

                return None

            devices = data.get("data", {}).get("items", [])

            return devices[0]["id"] if devices else None

        except json.JSONDecodeError:

            print(f"❌ Failed to decode JSON for {hostname}: {response.text}")

            return None

    else:

        print(f"❌ API Error ({response.status_code}): {response.text}")

        return None
