Office 365 – Microsoft Graph and Graph Explorer

Hi All,

Recently I got a chance to work on Office 365 groups. Requirement is I need to list all groups to those I belong to (current user groups). So here Microsoft Graph comes to picture. Here I’ll discuss Microsoft Graph, Microsoft Graph APIs, Graph Explorer.

What is Microsoft Graph?

Microsoft Graph provides APIs for developers to access data across Microsoft cloud.

Its built on the top of Office 365. Previously Microsoft Graph is known as Office 365 unified API.

Microsoft Graph exposes APIs, data across Office 365 and Azure AD. We can query to Users, Groups, Mail, Calendars, OneDrive, Azure Active Directory, OneNote, Planner, and so on.

Microsoft Graph exposes RESTFul services.

It provide single endpoint : to communicate with different Office 365 cloud services like SharePoint Online, Planner, Yammer, Office 365 Groups, Office 365 Users etc.

Currently Microsoft Graph API v1.0 is stable version available and beta also available.

For details what we can do with Microsoft Graph  please have a look at examples given-

To read or write cloud service resource such as User, Email, Office 365 Group and so on we need to create the request as{version}/{resource}?query-parameters where

{version}: Graph API version. Current version is 1.0.

{resource}: Like User, Email, Office 365 Group and so on.

query-parameters: Optional parameter to filter the response. For more details on query-parameters please have a look once

What is Microsoft Graph Explorer?

Microsoft Graph Explorer is a tool to test the Microsoft Graph Queries. We can access Microsoft Graph Explorer with URL – .

We need to sign in with our Office 365 account to test our queries. By default, it uses sample account. We need to sign in with Microsoft account from option available at left side as

We could also set the permissions like against which Office 365 services we can execute queries as

As we click on “modify permissions” link, “Modify Permissions” dialog appears as
