python request.post for oauth2 token error

Question

Below my code to get an oauth2 token,which always returns a 900114 error 'request body must contain grant_type' However if data contains only grant_type then it errors because scope is missing

I dont seem to be able to put both grant_type and scope in data

where am i going wrong?

#ver 24/01/26

import requests

import json

import sys

def get_new_token():

client_id = "xxxx"  

client_secret = "yyyy" 

tenant_id = "zzzz" 

scopes= "https://graph.microsoft.com/.default"

auth_server_url =  f"https://login.microsoftonline.com/{



data={'grant_type':'client_credentials','scope':scopes}

auth_header =  (client_id,client_secret)



response = requests.post(auth_server_url,json =data,auth=auth_header,headers={"Content-Type":"application/x-www-form-urlencoded"})



token_response=response.json()

print("New Token: ", token_response.get('access_token'))

print(type(response))

print(response.status_code)

print(response.content)

tokens = json.loads(response.text)
token = get_new_token()

Hi @John Selby ,

Thanks for reaching out to Microsoft Q&A.

The error message you're seeing, 'request body must contain grant_type', typically indicates that there's an issue with the way you're formatting your data for the POST request.

You can use below code which worked for me:

import requests
import json

def get_new_token():

    client_id = 
    client_secret = 
    tenant_id = 

    scope = "https://graph.microsoft.com/.default"

    token_url = f"https://login.microsoftonline.com/{

    payload = {
        "grant_type": "client_credentials",
        "client_id": 
        "client_secret": 
        "scope": scope
    }

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

    response = requests.post(token_url, data=payload, headers=headers)

    response.raise_for_status()

    token_response = response.json()

    print("New Token:", token_response.get("access_token"))
    print("Response Type:", type(response))
    print("HTTP Status Code:", response.status_code)
    print("Raw Response Content:", response.content)

    return token_response.get("access_token")

token = get_new_token()

Output:

New Token: <Token_generated>
Response Type: <class 'requests.models.Response'>
HTTP Status Code: 200
Raw Response Content: b'{"token_type":"Bearer","expires_in":3599,"ext_expires_in":3599,"access_token":"eyJ0eXXXXXXLCecZw"}'

Hope this helps!
