How to get Office 365 Groups using Microsoft Graph API

In this tutorial, we will discuss how to get Office 365 groups using Graph API.

Also, we will see how to create the security token in Azure which we can use inside the console application.

I will also show, how to get user profile details using Graph API.

As we know Microsoft has provided an easy way to get and test the API in Microsoft graph explorer. You can find the URL here.

https://developer.microsoft.com/en-us/graph/graph-explorer/

Here I just tested the graph api to get the all groups.

Before going to start, verify you have an account to access Microsoft Azure. You can log in the azure account through given URL https://portal.azure.com/#home

Create the security token in Azure cloud

Step 1: Login to the Azure account

Step 2: Next go to the App registrations and click on New registration.

Step 3: Next give your application name and choose the account type as below screenshot. Next click on Register.

Step 4: Once you register your account, you will get three keys which will help you to use in your application for security purpose.

Step 5: Next go to the API Permission and Add permission.

Step 6: Next go to Application permission to provide the permission.

Step 7: Here you can check the permission and click on Add Permission.

Step 9: After you allow the permission. it will come like below screenshot.

Step 10 : Next go to the Certificate and Secrets to generate a secret key.

Step 11: While creating the secret key, you have to provide the Expires of your key.

Step 12: After i add the key, below is my Secret key which is created. So now I am ready to use this API and keys in my application.

Get Office 365 Groups using Microsoft Graph API

Now, we will create a console application and then we can see how to get office 365 groups using Graph API.

Step 13: Go to the Visual Studio -> Create a console application and use the below code to get the groups.

using Microsoft.Graph;
using Microsoft.Graph.Auth;
using Microsoft.Identity.Client;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace ConnectWithSharePointOnline
{
    class Program
    {
        static void Main(string[] args)
        {
            try
            {
                GetUsersAsync().GetAwaiter().GetResult();
            }
            catch (Exception ex)
            {
                Console.WriteLine(ex.Message);
            }
            Console.ReadLine();
        }

        public async static Task GetUsersAsync()
        {
            var clientId = "c42f28e2-6d35-4abf-abd5-fe7b2874ff47";
            var tenantId = "a22d2591-6b37-4be3-b226-22d374c8818b";
            var SecretKey = "_718_H0sf8l4P6U~1c0EGSawbIyH.Ev-H~";
            IConfidentialClientApplication confidentialClientApplication = ConfidentialClientApplicationBuilder
                .Create(clientId)
                .WithTenantId(tenantId)
                .WithClientSecret(SecretKey)
                .Build();

            ClientCredentialProvider authProvider = new ClientCredentialProvider(confidentialClientApplication);
            GraphServiceClient graphClient = new GraphServiceClient(authProvider);

            var groups = await graphClient.Groups.Request().Select(x => new { x.Id, x.DisplayName,x.Members }).GetAsync();
            foreach (var group in groups)
            {
                Console.WriteLine($"{group.DisplayName}, {group.Id},{ group.Members}");
            }
        }
    }
}

Step 14: You will get a reference error, so please install the below NuGet package in your application to avoid reference issue.

Install-Package Microsoft.Graph  
Install-Package Microsoft.Graph.Auth -IncludePrerelease

Step 15: Below is the output of the code .

Get User Profile Details using Graph API

We can also easily get the user profile details using Graph API.

using Microsoft.Graph;
using Microsoft.Graph.Auth;
using Microsoft.Identity.Client;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace ConnectWithSharePointOnline
{
    class Program
    {
        static void Main(string[] args)
        {
            try
            {
                GetUsersAsync().GetAwaiter().GetResult();
            }
            catch (Exception ex)
            {
                Console.WriteLine(ex.Message);
            }
            Console.ReadLine();
        }

        public async static Task GetUsersAsync()
        {
            var clientId = "c42f28e2-6d35-4abf-abd5-fe7b2874ff47";
            var tenantId = "a22d2591-6b37-4be3-b226-22d374c8818b";
            var SecretKey = "_718_H0sf8l4P6U~1c0EGSawbIyH.Ev-H~";
            var clientApplication = ConfidentialClientApplicationBuilder
    .Create(clientId)
    .WithTenantId(tenantId)
    .WithClientSecret(SecretKey)
    .Build();

            // Create ClientCredentialProvider that will manage auth token for you
            var authenticationProvider = new ClientCredentialProvider(clientApplication);
            var graphClient = new GraphServiceClient(authenticationProvider);

            // Call Graph API
            var user = await graphClient.Users["[email protected]"].Request().GetAsync();
Console.WriteLine(user.DisplayName + "\n" + user.JobTitle + "\n" + user.MobilePhone + "\n" + user.Mail + "\n" + user.PreferredLanguage);
        }
    }
}

Please try and let me know if you are facing any issue.
