Office 365 – Azure Active Directory – Registering/Creating new Azure App – detailed steps

Hi All,
Today one more interesting topic to discuss 🙂
In this article we will discuss the detailed steps for creating / registering new app from Azure Active Directory
Background: Recently got a chance to use Graph API for getting Office 365 Group Admins. We have use case to check whether our Office 365 group has more than two owners or not. We have console application and using CSOM to get the group owners. To use the GRAPH APIs, authentication and authorization mechanism is bit different. We need to use the Azure AD.
So, to access Microsoft GRPAH APIs we need to create the new Azure App and need to give the permissions to respective APIs to access the respective data. Here, in our case to access O365 groups we have following high level steps:
- Register / Create new Azure App from “Azure Active Directory” center
- Get the APPID and Client Secret Key
- Give the permission to access o365 Group owners to our newly created app to access GRAPH APIs
- Generate the authentication token in our program
- Use authentication token to use the GRAPH APIs
In this article we will go in details for two points – Register / Create new Azure App from “Azure Active Directory” center and generating new client secret key. We will have detailed steps as below.
Steps to Register / Create Azure App:
- Login to O365 Admin site –
https://admin.microsoft.com/AdminPortal/Home#/homepage - Go to the “Azure Active Directory” center as shown in below snap

Hello Prasham..thank you so much for sharing this article. I was doing a POC by reffering your article and like to bring to your kind attention a small correction to Admin Center reference in starting of the article.
I.e. “Steps to Register / Create Azure App:
Login to SharePoint Admin site – https://-admin.sharepoint.com here in my case – https://knowledgejunction-admin.sharepoint.com”
This should be “Login to Microsoft Office365 Admin Center” using URL below:
https://admin.microsoft.com/AdminPortal/Home#/homepage
Please review once.
Thank you once again Prasham, for sharing this knowlegde and motivating all of us..please continue.
Thanks Abdul. This is very good catch 🙂
