Cannot query graph.microsoft.com API

Question

I'm trying to use the graph.microsoft.com API to retrieve users and channels from Microsoft Teams and send messages to those channels. I'm using Python and trying to accomplish these tasks.

Access token fetch through msal library using oauth 2.0 (initiate_auth_code_flow + acquire_token_by_auth_code_flow)

import requests

url = "https://graph.microsoft.com/v1.0/users"
headers = {
    "Authorization": "Bearer <TOKEN>",
    "Content-Type": "application/json"
}

response = requests.get(url, headers=headers)

print(response.content)

However, I'm encountering different errors depending on the endpoint used:

1. For /me, I receive a valid response.

   {"@odata.context":"https://graph.microsoft.com/v1.0/$metadata#users/$entity","userPrincipalName":"******@bugbug.io","id":"905eed23ad42a35c","displayName":"BugBug IT","surname":"IT","givenName":"BugBug","preferredLanguage":"en-US","mail":"******@bugbug.io","mobilePhone":null,"jobTitle":null,"officeLocation":null,"businessPhones":[]}'
   

1. For /users, I receive an InternalServerError with the message "Invalid response. Expected list response must have value property."

   {"@odata.context":"https://graph.microsoft.com/v1.0/$metadata#users","value":[{"error":{"code":"InternalServerError","message":"Invalid response. Expected list response must have value property.","innerError":{"date":"2024-02-16T07:52:25","request-id":"f5c6afb6-1435-4eee-8bc4-8987ef335eed","client-request-id":"f5c6afb6-1435-4eee-8bc4-8987ef335eed"}}}
   

1. For /users/{userId}/chats, I receive a Forbidden error with the message "No authorization information present on the request."

   {"error":{"code":"Forbidden","message":"No authorization information present on the request.","innerError":{"date":"2024-02-16T07:52:26","request-id":"0a73d36b-cf32-47cc-9a31-9aa41fb2afe3","client-request-id":"0a73d36b-cf32-47cc-9a31-9aa41fb2afe3"}}}
   

Also, here are the scopes I'm using for the permissions (defined in my Application).

• Channel.ReadBasic.All
• ChannelMessage.Send
• Chat.Create
• Chat.Read
• Chat.ReadBasic
• Chat.ReadWrite
• Chat.ReadWrite.All
• ChatMember.Read
• ChatMessage.Read
• ChatMessage.Send
• Directory.AccessAsUser.All
• Directory.Read.All
• profile
• User.Read
• User.Read.All
• User.ReadBasic.All

Answer 2

Hi @BugBug IT

This is the expected error. The /users endpoint and /users/{userId}/chats endpoint do not support personal or guest accounts. Please log in with a work account that has an Office 365 license and obtain an access token.

Hope this helps.
