Using Graph API to Retrieve Email

How can I use the Graph API to pull a newsletter from an email address and load it into my internal web application? I plan to initially retrieve the email from a mailbox using PowerShell, but I'm open to using PHP/AJAX or another method if that would be better suited. I would appreciate some guidance on how to set up API access. I have already created the app registration and a secret, but I'm not sure if that's the correct way to set it up.

    Let’s break down the steps to achieve this:

    • You’ve already created an app registration and obtained a client secret. Great! Make sure you’ve granted the necessary permissions to your app. Specifically, you’ll need the Mail.Read permission to read emails.
    • If you haven’t done so, navigate to your app registration in the Azure Active Directory (Azure AD) portal and add the required permissions.
    • In your PHP code, use the Microsoft Graph REST API to make requests.
    • Obtain an access token using your app registration credentials (client ID and secret).
    • In your web application, handle authentication. You can use the OAuth 2.0 authorization code flow to obtain an access token.
    • Redirect users to the Microsoft login page to grant consent.
    • Exchange the authorization code for an access token.
    • Make an HTTP request to the Graph API endpoint for fetching emails which is: https://graph.microsoft.com/v1.0/me/messages.
    • You can filter emails based on criteria such as sender, subject, or date range.
    • Parse the response to extract relevant email content (e.g., newsletter text, attachments).
