Power Bi REST API - 401 Authorization error when using app secret

I have a console app that uses the REST API to get a dataset (and later add rows to it). This works when I supply my own user/password credentials.   Now I have registered the app as a Web/API app ...

    Hi tripleacoder,

     

    As far as I know, the permissions of Power BI are all based on the users. So an App can't act as a user. Please refer to developer/power-bi-permissions where all the descriptions have "user". 

    Regarding "Tenant.ReadWrite.All", the documentation above also has a description. Actually, these permissions only can retrieve the profiles rather than data. Please refer to admin/reports_getreportsasadmin.

    One simple proof we can see is that even an admin can't access all the App workspaces. The data is the precious asset of a company. I think this is reasonable.

     

     

    Best Regards,
    Dale

Could you try to mention an access level in API request?

 

https://docs.microsoft.com/en-us/rest/api/power-bi/embedtoken/reports_generatetoken#tokenaccesslevel

 

 

I'm not sure what you mean. The link goes to "Required access level for EmbedToken generation", but I'm not using the Embed Token API.

 

I get the token using this code:

 

 

const string authorityUri = "https://login.microsoftonline.com/" + tenantId;

AuthenticationContext authContext = new AuthenticationContext(authorityUri);

        
AuthenticationResult result = null;
         
result = await authContext.AcquireTokenAsync(resourceUri, clientCredential);
