What are the different ways to get SharePoint Site Collection using Microsoft Graph

Microsoft Graph API has a single endpoint, which allow us to access any data across Office 365 environment by using different parameters. This post explores the different ways of retrieving the Site Collection using MS Graph API from Microsoft Graph Explorer.

• Navigate to Microsoft Graph Explorer
• Select the GET method from Request drop down
• Select the version as v1.0 or beta
• Enter the API endpoint to the request textbox and then click Run Query button to run the Graph request.
• Use the Permissions section to agree the scopes required for accessing the API.

To read site collection related information, we must agree Site.Read.All permission scope

We can access the site collection using three different ways in Microsoft Graph API,

• By using root
• By using Site ID
• By using Site server relative URL.
• By using Group ID
