Hi Vinothkumar8,
Thanks for the query.
Office 365 services, such as OneNote, Outlook, Excel, OneDrive, Microsoft Teams, Planner, and SharePoint, are now exposed in Microsoft Graph. Microsoft Graph is a unified API endpoint for accessing data across Microsoft 365, which includes Office 365, Enterprise Mobility, and Security and Windows services. It provides a simplified developer experience, with one endpoint and a single authentication token that gives your app access to data across all these services.
Microsoft Graph is the gateway to data and intelligence in Microsoft 365. You can use the Microsoft Graph API to build apps for organizations and consumers that interact with the data of millions of users. With Microsoft Graph, you can connect to a wealth of resources, relationships, and intelligence, all through a single endpoint: https://graph.microsoft.com.
