Realtime Push URL returning 401 from app integration (though works fine from cURL)
I am trying to setup an integration with Power BI Service for ingesting real time data. I have configured the data set and a dashboard as per the documentation.
When I test using cURL (with the provided code when setting up the API) it works fine - i see the data populated into the dashboard. However when I use the push URL in my application I can see the data going out, but getting a 401 from PowerBI - I have compared the headers, URL and everything looks fine. I can't for the life of me work out what is causing the 401
"For streaming datasets created using the Power BI service UI, as described in the previous paragraph, Azure AD authentication is not required. In such datasets, the dataset owner receives a URL with a rowkey, which authorizes the requestor to push data into the dataset with out using an Azure AD OAuth bearer token. "
as such the URL with embedded key should be enough (and indeed, with cURL it is) - is there any way to debug why I am getting this issue? does anyone know why this issue is occurring?
