How to fix {"error":{"code":"unauthenticated","message":"Unauthenticated"}}

Question

Hello,

I'm encountering an "Unauthenticated" error when uploading files via my Laravel application integrated with Microsoft Graph. The application has been functioning correctly until February 13, 2024. Since then, attempts to upload files result in a PUT request to https://my.microsoftpersonalcontent.com/personal/ac79a1ee349ed191/_api/v2.0/drives/bXXXXXXXXXXXX returning an "Unauthenticated" error.

I've tried generating a new token from code, but the issue persists.

I understand that Microsoft is deprecating Azure AD Graph APIs in favor of Microsoft Graph, with a complete cutoff for requests from existing applications effective February 1, 2025.

Could this change be affecting my application's authentication? If so, what steps should I take to resolve this issue?

Thank you for your assistance.

Hi Aayush Niraula,

Thank you for reaching out to Microsoft!

Yes, the deprecation of Azure Active Directory (Azure AD) Graph can indeed impact your application's authentication. Since Azure AD Graph is on its path to retirement, it is highly recommended that you migrate your applications to Microsoft Graph to ensure seamless functionality.

Go to the Microsoft Entra admin center and navigate to Identity>Overview>Recommendations.

Locate the Recommendation - Find the recommendation related to Azure AD Graph API usage.

Click on the recommendation to view more details. This will provide you with information about the applications or service principals using the Azure AD Graph API.

Look for the ID number associated with the high incident. This ID will help you identify the specific application or service principal causing the issue.

For the rest, please read our recently updated Blog Post in this regard:
