How to Integrating Microsoft Graph API for Sending Emails with Laravel 11

Question

I'm looking to integrate Microsoft Graph API for sending emails within a Laravel 11 application. Specifically, I need guidance on how to set up and use the Microsoft Graph API to send emails programmatically. Here are some details and questions I have about the integration:

Microsoft Graph API Setup:

• How do I register my Laravel application in the Azure portal to get the necessary credentials (client ID, tenant ID, client secret)?
  • What permissions do I need to grant for sending emails?
  Authentication:

  - What is the recommended approach to authenticate and obtain an access token from Microsoft Graph API in a Laravel 11 application?
  
     - Are there specific Laravel packages or libraries that facilitate this integration?
  
     **Sending Emails:**
  
        - What is the process to send an email using the Microsoft Graph API once authenticated?
  
           - Can you provide a code example or guide on how to use the Graph API to send an email from Laravel?
  
           **Error Handling:**
  
              - What are common issues or errors I should be aware of during the integration process?
  
                 - How should I handle and troubleshoot authentication or API call failures?
  
                 **Best Practices:**
  
                    - Are there best practices or recommendations for integrating Microsoft Graph API with Laravel to ensure security and efficiency?
  

Any help or resources on these points would be greatly appreciated. Thank you!

Hi @Thilina CL

Register the application in Azure by referring to this document. After registration, you can view clientID and tenantI in Overview. For Client secrets, you can manually add them in Certificates&secrets.

For sending mails, you need to add Mail.Send permission. For more information, see this document.

The recommended methods for obtaining tokens are auth code flow and client credentials flow

Auth code flow requires the user to log in interactively, and the application can only send emails on behalf of the logged in user.

Client credentials flow does not require the user to log in, but requires the administrator to grant the application permission Mail.Send, which can send messages on behalf of any user.

Hope this helps.
