Hello Daiman

To access your Microsoft account using the Microsoft Graph API, you’ll need to follow these steps:

1. Register Your App: Go to the Azure portal. Create a new App Registration. Note down the Application (client) ID and Directory (tenant) ID.
2. Configure Permissions: In your app registration, navigate to API permissions. Add the necessary permissions based on the resources you want to access. Some common permissions include: User.Read: Read basic profile information of the signed-in user. Mail.Read: Read the user’s mailbox. Calendars.Read: Read the user’s calendar events. Adjust permissions according to your use case.
3. Authentication Endpoint: The authentication endpoint for Microsoft Graph is:

        https://login.microsoftonline.com/{tenant-id}/oauth2/v2.0/authorize
        
   

   Replace {tenant-id} with your Directory (tenant) ID.
4. Access Token Endpoint: To obtain an access token, make a POST request to the following endpoint:

        https://login.microsoftonline.com/{tenant-id}/oauth2/v2.0/token
        
   

   Include the required parameters: client_id, scope, client_secret, grant_type, and redirect_uri.
5. Construct API Requests: Use the access token to construct requests to the Microsoft Graph API. The base URL is:

        https://graph.microsoft.com/v1.0/
        
   

   Append the specific resource path (e.g., /me, /users/{user-id}, /me/messages, etc.) to the base URL.
6. Example Request: To get the current user’s profile:

        GET https://graph.microsoft.com/v1.0/me
        
   

7. Interpret the Response: The response will be in JSON format. Parse it to extract the relevant data.
