Error 400 - Bad Request an Creating user with Microsoft Graph

Question

I am trying to create a new user in my tenant using Microsoft Graph (v1.0) with help of the Microsoft doc.
When I create my user, I always get an error 400 bad request as response.

I am using HttpClient to make the post Request.

My Function :

private async Task<string> BuildUser(string token, string query)
    {
        httpClient.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", token);
        UserCreation uc = new UserCreation
        {
            accountEnabled = this.checkBoxActive.Checked,
            displayName = this.textBoxDN.Text,
            mailNickName = this.textBoxMail.Text,
            passwordProfile = new PasswordProfile { forceChangePasswordNextSignIn = this.checkBoxChangeMDP.Checked, password = this.textBoxPassword.Text},
            userPrincipalName = this.textBoxUPN.Text
        };

        string json = JsonConvert.SerializeObject(uc);
        var content = new StringContent(json, Encoding.UTF8, "application/json");
        HttpResponseMessage response = httpClient.PostAsync(query, content).Result;
        return response.ToString();
    }

My token is valid and i am able to make simple Get requests, my app have the authorizations mentioned here.

For example, my json var can contains :

{
    "accountEnabled":true,
    "displayName":"cyril testgraphh",
    "mailNickName":"cyriltestgraphh",
    "userPrincipalName":"[email protected]",
    "passwordProfile":{
        "forceChangePasswordNextSignIn":true,
        "password":"XXX"
    }
}

EDIT : I solved my problem by using Microsoft Graph objects (Microsoft.Graph.User and Microsoft.Graph.PasswordProfile) and add .onmicrosoft.com to my upn

Are you able to perform other actions or is it just this action that fails? — Dimitri
Yes, I am able to make simple Get Requests like https://graph.microsoft.com/v1.0/users/ or https://graph.microsoft.com/v1.0/users?$filter=startswith(displayname,'someName') — Challouatte Cyril
Bad Request means something is not in the right expected format (docs.microsoft.com/en-us/graph/errors), can you try using the 'GetAsync(uri)' method instead of the PostAsync()? Something like this: var response = await httpclient.GetAsync(Uri); Your Json format and content is OK so its not that. — Dimitri

You should check your code. I tried the following code, it works well.

using Microsoft.Graph;
using Newtonsoft.Json;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Net.Http;
using System.Net.Http.Headers;
using System.Text;
using System.Threading.Tasks;
 
namespace ConsoleApp4
{
    class Program
    {
        static void Main(string[] args)
        {
            HttpClient httpClient = new HttpClient();
            httpClient.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", token);
            UserCreation uc = new UserCreation
            {
                accountEnabled = true,
                displayName = "cyril testgraphh",
                mailNickName = "cyriltestgraphh",
                passwordProfile = new PasswordProfile { ForceChangePasswordNextSignIn = false, Password = "Password!" },
                userPrincipalName = "[email protected]"
            };
 
            string json = JsonConvert.SerializeObject(uc);
            var content = new StringContent(json, Encoding.UTF8, "application/json");
 
            HttpResponseMessage response = httpClient.PostAsync("https://graph.microsoft.com/v1.0/users", content).Result;
            Console.Write(response);
            Console.ReadLine();
        }
    }
    class UserCreation
    {
        public bool accountEnabled { get; internal set; }
        public string displayName { get; internal set; }
        public string mailNickName { get; internal set; }
        public string userPrincipalName { get; internal set; }
        public PasswordProfile passwordProfile { get; internal set; }
    }
 
}

And the response like this:

Error 400 - Bad Request an Creating user with Microsoft Graph
