Power Automate - REST API

Hi Prakash1050 

The "Unauthorized" error you're seeing is likely due to missing or incorrect permissions related to your Azure Active Directory (AAD) app, not having the right Power BI license, or incorrect OAuth authentication.

• Power Automate requires either a Power BI Pro or Premium Per User (PPU) license to access Power BI API resources.
• A trial environment without the correct license may cause this issue, especially if you're trying to interact with datasets in the Power BI Service.
• Also, Ensure that your AAD app has Dataset.Read.All permission under API Permissions in the Azure Portal.
• After assigning the permissions, don’t forget to Grant Admin Consent for those permissions in the Azure Portal.
• If you’re missing the Power BI Pro license or don't have the right permissions in the workspace, those will cause authorization issues.
• You'll need to get the appropriate license and verify the permission setup in Azure AD.
