3. Overview of Microsoft Graph
Users Groups Outlook Calendar SharePoint
Dynamics
365 Central
Intune
Teams Azure AD
OneDrive Planner
https://graph.microsoft.com
Your app
Gateway to data
Unified programmability
model
Single endpoint
Graph Connector:
Delivering external data
to the Microsoft cloud
into Microsoft Graph
services and applications
Data Connect: Delivery of
Microsoft Graph data to
popular Azure data
stores

4. Overview of Microsoft Graph - Contd
Accessing
Microsoft
Graph
Microsoft
Graph REST
API
Any platform and framework
Issue HTTP Requests and
process Responses
Microsoft
Graph
Native SDKs
Abstract layer for constructing,
submitting and processing REST
requests & responses
SDK for .NET, iOS, Android, Java,
PHP, Python, JavaScript, Node.js
etc
Pre-requisites
• Application in Microsoft
identity platform
• Establish trust
relationship between
the app and identity
provider
• Web
• Mobile/desktop app
• Web API

5. Overview of Microsoft Graph - Contd
• Filter, Search, Count, Orderby, delta, expand..
Advanced queries
• Combine multiple requests in one HTTP call using JSON batching
Batching
• If an overwhelming no of request occurs, throttling helps maintain
optimal performance
Throttling
• Webhook mechanism to deliver change notification to clients
• Supports various no. of resources like Outlook, user, group, teams
chatmessage, SP List item etc
Change Notifications

6. Types of permissions
Microsoft Identity defines two types of permissions
• Access API as signed-in user
• User can consent for their data or admin can
consent for all users
Delegated permissions
• Access API as daemon/without user interaction
• Only global admin can consent
Application permissions

7. Authentication Flows / Permission
Models
Delegated
Permissions
•Authorization Code

9. Demo - Dotnet Core Graph SDK & MSAL
Microsoft
Authentication
Library (MSAL)
Enables developers to acquire tokens
On behalf of user or on behalf of application
Maintains token cache and refreshes tokens when close to expire
Available for different platforms
NPM, Nuget
Graph SDK Simplifies graph calls
Application Permissions
• Client Credentials
Delegated Permissions
• On behalf of
• Device code flow
