404 Client Error: Not Found for url https://api.powerbi.com/v1.0/myorg/groups/{workspaceId}/datasets

Hey Anonymous,

Quick Fix for Your 404 Error

The Problem: Your service principal doesn't have access to datasets owned by others.

Solution Steps:

1. Add Service Principal to Workspace
   • Go to workspace settings → Access tab
   • Add your App ID as Member/Admin role
2. Get Dataset Permissions
   • Ask dataset owner to share dataset with your service principal
   • Or get added as workspace admin to bypass this
3. Check Tenant Settings
   • Power BI admin portal → "Service principals can use APIs" must be ON
   • Usually already enabled in most orgs
4. Test It
   url = f'https://api.powerbi.com/v1.0/myorg/groups/{workspaceId}/datasets/{datasetId}/refreshes?$top=1'

Pro Tip: If you're hitting this often, ask for a dedicated "API workspace" where all shared datasets live and your service principal has permanent access.

Still getting 404? Double-check your workspaceId and datasetId are correct. Sometimes copying from URL gives wrong IDs.

That's it. The permissions thing trips up everyone initially - you're not alone on this one.
