fms_url = "https://fms.tp.entsoe.eu/downloadFileContent"
username = "YOUR_TP_EMAIL"
password = "YOUR_TP_PASSWORD"
client_id = "tp-fms-public"

# Get token request
payload = {

    "grant_type": "password",
    "username": username,
    "password": password
}

headers = {
    'Content-Type': 'application/x-www-form-urlencoded'

# Download file request 
response = requests.post(keycloak_url, headers=headers, data=payload)
access_token = response.json().get("access_token")
print(access_token)



payload = json.dumps({
  "folder": "/TP_export/ActualTotalLoad_6.1.A_r3/",
  "filename": "2014_12_ActualTotalLoad_6.1.A_r3.csv",

status_code = response.status_code

if(status_code == 200):
    with open("downloaded_file.csv", "w", encoding="utf-8", newline="") as f:
      f.write(response.text)
      print("File saved.")
else:
    print(f"File can not be retrieved, html response status code = {status_code}")
