Microsoft Dynamic 365 business Central API data fetch using Fabric note book

My company’s IT team has built APIs to access Microsoft Dynamics 365 Business Central data. I successfully tested these APIs using Postman. However, when I try to call the API to obtain the bearer access token from a Python script in a Microsoft Fabric notebook, it does not work. Below is the Python script I am using. I do not want to use data flows for this. Please note that this API fetches data only for a specific Azure AD account.

If this script isn’t the best approach, I’m open to trying alternative scripting methods

import requests
from urllib.parse import urlencode, urlparse, parse_qs
import webbrowser

tenant_id = "tenant_id"
client_id = "client_id"
client_secret = "client_secret"
redirect_uri = "https://oauth.powerbi.com/views/oauthredirect.html"
scope = "https://api.businesscentral.dynamics.com/.default"

# === OAuth Endpoints ===
auth_url = f"https://login.microsoftonline.com/{tenant_id}/oauth2/v2.0/authorize"
token_url = f"https://login.microsoftonline.com/{tenant_id}/oauth2/v2.0/token"

# === Direct to login page ===
params = {
    "client_id": client_id,
    "response_type": "code",
    "redirect_uri": redirect_uri,
    "response_mode": "query",
    "scope": scope,
}
full_auth_url = f"{auth_url}?{urlencode(params)}"
webbrowser.open(full_auth_url)
print("Please login and paste the full redirect URL below.")

# === Capture the code from the redirect ===
redirect_response = input("Paste the full redirect URL here: ")
code = parse_qs(urlparse(redirect_response).query).get("code", [None])[0]

# === Exchange code for token ===
token_data = {
    "grant_type": "authorization_code",
    "code": code,
    "redirect_uri": redirect_uri,
    "client_id": client_id,
    "client_secret": client_secret,
    "scope": scope
}

token_response = requests.post(token_url, data=token_data).json()

# === Get Access Token ===
if "access_token" in token_response:
    access_token = token_response["access_token"]
    print("\n Access Token:\n", access_token)
else:
    print("\n Failed to acquire token:\n", token_response)
