Create a new user in Azure Active Directory (B2C) with Graph API, using http post request

Question

I have previously been adding users programmatically using Active Directory Authentication Library (ADAL), but now I need to define \"signInNames\" (= users email), and that

Answer 1

Thank you for your response Fei Xue, i believe i had the right permissions. What i did to solvem my problem.

First off i removed my own custom class "NewUser", then i downloaded this sample-project: https://github.com/AzureADQuickStarts/B2C-GraphAPI-DotNet/blob/master/B2CGraphClient/B2CGraphClient.cs to eliminate the risk that my code was wrong. I modified it to support my needs, then i created a simple JObject:

var jsonObject = new JObject
                        {
                            {"accountEnabled", true},
                            {"country", customer.CustomerBase.Company},
                            {"creationType", "LocalAccount"},
                            {"displayName", pendingCustomer.Email.Trim()},
                            {"passwordPolicies", "DisablePasswordExpiration,DisableStrongPassword"},
                            {"passwordProfile", new JObject
                            {
                                {"password", pwd},
                                {"forceChangePasswordNextLogin", true}
                            } },
                            {"signInNames", new JArray
                                {
                                    new JObject
                                    {
                                        {"value", pendingCustomer.Email.Trim()},
                                        {"type", "emailAddress"}
                                    }
                                }
                            }
                        };

client = new B2CGraphClient(ClientId, ClientSecret, TenantId);
var response = await client.CreateUser(jsonObject.ToString());
var newUser = JsonConvert.DeserializeObject(response);

From B2CGraphClient.cs

        private async Task SendGraphPostRequest(string api, string json)
    {
        // NOTE: This client uses ADAL v2, not ADAL v4
        var result = authContext.AcquireToken(Globals.aadGraphResourceId, credential);
        var http = new HttpClient();
        var url = Globals.aadGraphEndpoint + tenant + api + "?" + Globals.aadGraphVersion;

        var request = new HttpRequestMessage(HttpMethod.Post, url);
        request.Headers.Authorization = new AuthenticationHeaderValue("Bearer", result.AccessToken);
        request.Content = new StringContent(json, Encoding.UTF8, "application/json");
        var response = await http.SendAsync(request);

        if (!response.IsSuccessStatusCode)
        {
            var error = await response.Content.ReadAsStringAsync();
            var formatted = JsonConvert.DeserializeObject(error);
            //Console.WriteLine("Error Calling the Graph API: \n" + JsonConvert.SerializeObject(formatted, Formatting.Indented));
            Logger.Error("Error Calling the Graph API: \n" + JsonConvert.SerializeObject(formatted, Formatting.Indented));
        }
        Logger.Info((int)response.StatusCode + ": " + response.ReasonPhrase);

        return await response.Content.ReadAsStringAsync();
    }

This finally solved all my problems, it was probably an format-error in the serialization of my NewCustomer-class, which then got rejected by the API.
