Prerequisites for Using Microsoft Graph HTTP Requests

Azure AD Authentication Setup

Before using Microsoft Graph HTTP Requests, you need to configure Azure Active Directory (Azure AD) authentication. This setup ensures secure access to Microsoft 365 services. The process involves several steps:

1. Your application requests an access token using the Office.js API.

2. If you're not signed in, the Office host prompts you to sign in and provide consent.

3. The Office host then requests an access token from the Microsoft identity platform.

4. The platform returns a token that grants access to the app's APIs.

5. The app sends this token to the server-side API.

6. The server validates the token and uses the OAuth 2.0 On-Behalf-Of flow to request a new token for Microsoft Graph.

7. The Microsoft identity platform issues a new token with permissions for Microsoft Graph.

8. Finally, the server uses this token to make requests to the Microsoft Graph API.

This process ensures that only authorized users and applications can access sensitive data.

Required Permissions Overview

Permissions play a critical role in using Microsoft Graph HTTP Requests. Microsoft Graph follows the principle of least privilege, allowing you to request only the permissions your app needs. This approach minimizes security risks and builds user trust.

• Avoid granting excessive permissions, as they can create vulnerabilities. For example, permissions like Directory.AccessAsUser.All provide broad access and should only be used when absolutely necessary.

• Instead, opt for lesser-privileged permissions whenever possible.

• Microsoft Entra ID also limits the number of permissions based on your app's audience, ensuring compliance with best practices.

By carefully managing permissions, you can maintain security while enabling your app to perform its required tasks.
