Getting 400 Bad request when sending POST request to Azure Graph API

Question

I am trying to send POST request to Microsoft Azure Graph API for User creation. I have referred their sample example and able to execute GET request successfully but not POST.

My code is as below:

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.io.OutputStream;
import java.net.HttpURLConnection;
import java.net.URL;
import java.net.URLEncoder;
import java.util.LinkedHashMap;
import java.util.Map;
import java.util.concurrent.ExecutorService;
import java.util.concurrent.Executors;
import java.util.concurrent.Future;

import javax.naming.ServiceUnavailableException;

import org.json.JSONException;
import org.json.JSONObject;

import com.microsoft.aad.adal4j.AuthenticationContext;
import com.microsoft.aad.adal4j.AuthenticationResult;

public class CreateUser {

    private final static String AUTHORITY = "https://login.microsoftonline.com/common/";
    private final static String CLIENT_ID = "<Client_id>";

    public static void main(String args[]) throws Exception {

        try (BufferedReader br = new BufferedReader(new InputStreamReader(
                System.in))) {
            System.out.print("Enter username: ");
            String username = br.readLine();
            System.out.print("Enter password: ");
            String password = br.readLine();

            // Request access token from AAD
            AuthenticationResult result = getAccessTokenFromUserCredentials(
                    username, password);
            // Get user info from Microsoft Graph
            String userInfo = createUserInGraph(result.getAccessToken());
            System.out.print(userInfo);
        }
   }

    private static AuthenticationResult getAccessTokenFromUserCredentials(
            String username, String password) throws Exception {
        AuthenticationContext context;
        AuthenticationResult result;
        ExecutorService service = null;
        try {
            service = Executors.newFixedThreadPool(1);
            context = new AuthenticationContext(AUTHORITY, false, service);
            Future<AuthenticationResult> future = context.acquireToken(
                    "https://graph.microsoft.com", CLIENT_ID, username, password,
                    null);
            result = future.get();
        } finally {
            service.shutdown();
        }

        if (result == null) {
            throw new ServiceUnavailableException(
                    "authentication result was null");
        }
        return result;
    }

    private static String createUserInGraph(String accessToken) throws IOException {

        String jsonInputData = "{  \"accountEnabled\": true," + 
                "  \"city\": \"Delhi\"," + 
                "  \"country\": \"India\"," + 
                "  \"department\": \"Human Resources\"," +

                "    \"password\": \"Test1234\"," + 
                "    \"forceChangePasswordNextSignIn\": false" + 
                "  }," + 
                "  \"officeLocation\": \"131/1105\"," + 
                "  \"postalCode\": \"98052\"," + 
                "  \"preferredLanguage\": \"en-US\"," +

                "  \"userPrincipalName\": \"adamg@alandonaldgmail.onmicrosoft.com\"}";

        System.out.println("Input: " + jsonInputData);
        URL url = new URL("https://graph.microsoft.com/v1.0/users");
        HttpURLConnection conn = (HttpURLConnection) url.openConnection();
        conn.setDoOutput(true);
        conn.setDoInput(true);
        conn.setRequestMethod("POST");
        conn.setRequestProperty("Authorization", "Bearer " + accessToken);
        System.out.println("Access Token: \n" + accessToken);
        System.out.println();
        conn.setRequestProperty("Content-type","application/json; charset=UTF-8");

        OutputStream os = conn.getOutputStream();
        os.write(jsonInputData.getBytes("UTF-8"));
        os.close();
        //display what returns the POST request

        StringBuilder sb = new StringBuilder();  
        int HttpResult = conn.getResponseCode();
        System.out.println("Response code: " + HttpResult);
        if (HttpResult == HttpURLConnection.HTTP_OK) {
            BufferedReader br = new BufferedReader(
                    new InputStreamReader(conn.getInputStream(), "utf-8"));
            String line = null;  
            while ((line = br.readLine()) != null) {  
                sb.append(line + "\n");  
            }
            br.close();
            System.out.println("" + sb.toString());  
        } else {
            System.out.println(conn.getResponseMessage());  
        }
        return null;
    }
}

So here I am getting error code as 400 and error message as 'Bad request'. Can somebody explain me what is the issue?

Answer 1

Bad Request issues are usually related to some invalid data/formatting being sent.

Looking at your json, two things stand out. Please make these changes and see if this resolves your issue.

1. "userPrincipalName": "adamg@alandonaldgmail.onmicrosoft.com" (make sure alandonaldgmail.onmicrosoft.com is a verified domain for your azure active directory organization, if it is not and you used it by mistake, then change the value for userPrincipalName to something like "adamg@yourazureadtenantname.onmicrosoft.com")

2. "usageLocation": "IND" (this should probably be just "IN", as it's supposed to be a two letter country code (ISO Standard 3166))

Referencing these from here - Update User API Reference

Answer 2

Ok, So I implemented it with HttpClient library. Below is code for the same:

int count = 1;
String jsonInputData = "{ "+
                "  \"accountEnabled\": true," + 
                "  \"displayName\": \"TestUserFromEclipse" +count+"\"," + 
                "  \"mailNickname\": \"mailNickname-value\"," +
                "  \"country\": \"IN\"," +
                "  \"userPrincipalName\": \"eclipseuser"+count+"@alandonaldgmail.onmicrosoft.com\"," + 
                "  \"passwordProfile\" : {" + 
                "    \"forceChangePasswordNextSignIn\": false," + 
                "    \"password\": \"Sigma@123\"" + 
                "  }" + 
                "}";

    HttpPost post = null;
        try {
            String url = "https://graph.microsoft.com/v1.0/users";
            StringEntity s = new StringEntity(jsonInputData);
            HttpClient client = HttpClientBuilder.create().build();
            post = new HttpPost(url);

            // add header
            post.setHeader("Content-Type", "application/json");
            post.setHeader("Authorization", "Bearer " + accessToken);
            post.setEntity(s);

            HttpResponse response = client.execute(post);
            System.out.println("Response Code : " 
                        + response.getStatusLine().getStatusCode());
        } finally {
            post.releaseConnection();
        }
