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

Anonymous — Mon, 11 Aug 2025 15:27:36 GMT

I am connecting via a call to the API like this (ie tenantid and service principal) :

app = msal.ConfidentialClientApplication(client_id, authority=authority_url, client_credential=secret_value)

result = app.acquire_token_for_client(scopes=scope)

accessToken = result['access_token']

headers = {

'Authorization': f'Bearer {accessToken}'

}

response = requests.request('get', url, headers)

url = f'https://api.powerbi.com/v1.0/myorg/groups/{workspaceId}/datasets/{datasetId}/refreshes?$top=1'

The above call works when I use a datasetId that I own but receives

404 Client Error: Not Found for url

when it a dataset that someone else owns

My code needs to run without me being connected. How do I resolve?

Hey @Anonymous,

Quick Fix for Your 404 Error

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

Solution Steps:

Add Service Principal to Workspace
- Go to workspace settings → Access tab
- Add your App ID as Member/Admin role
Get Dataset Permissions
- Ask dataset owner to share dataset with your service principal
- Or get added as workspace admin to bypass this
Check Tenant Settings
- Power BI admin portal → "Service principals can use APIs" must be ON
- Usually already enabled in most orgs
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.
