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

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.
