Azure RBAC Permissions for Blob access using Azure AD integrated login

(0) ShareShare
ReportReport
Posted on by

Greetings!

Trying to connect to Azure Storage blob container from Flow with a minimum of permissions.

 

Only need to read blobs from the container.

 

What is the minimum of permissions needed?


I have granted the user "Reader and Data Access" and "Reader" permissions on the Storage Account, and "Storage Blob Data Reader" on the Container.

 

I can successfully view the data through Azure Portal with this user.

 

 

But in Power Automate, I get the following error;

 

The dynamic invocation request failed with error: { "status": 403, "message": "Server failed to authenticate the request. Make sure the value of Authorization header is formed correctly including the signature.\r\nclientRequestId: xyz", "error": { "message": "Server failed to authenticate the request. Make sure the value of Authorization header is formed correctly including the signature." }, "source": "azureblob-xyz.azconn-xyz-003.p.azurewebsites.net" }.
