# Step 1: Generate TOTP
totp = pyotp.TOTP(valid_secret)
otp = totp.now()
print(f"✅ Generated TOTP: {otp}")
# Step 2: Generate Auth Code
login_data = {
"fyers_id": fyers_id,

print("Requesting auth code...")
login_response = requests.post("https://api.fyers.in/v3/login", json=login_data)
if not login_response.ok:
print(f"❌ HTTP Error: {login_response.status_code}")
print(login_response.text)
sys.exit(1)
res = login_response.json()
if res.get("code") != 200:
print(f"❌ Login failed: {res}")
sys.exit(1)
auth_code = res["data"]["auth_code"]
