Hi guys,
We want to use REST API of Power BI directly in Power BI Desktop and not via PowerShell.
I have a service principal which works in PowerShell.
How can I use REST API directly in Power BI Desktop with authenticating with a service principal.
Good to mention: I don't want to save the username and password a query.
Solved! Go to Solution.
Hi @AslanAli ,
I think you can try below code to get access token by Rest API with Service Principal.
() =>
let
body = "client_id=" & #"App ID"
& "&scope=https://analysis.windows.net/powerbi/api/.default&client_secret=" & #"App Secret"
& "&grant_type=client_credentials",
Data= Json.Document(Web.Contents("https://login.microsoftonline.com/"& TenantID & "/oauth2/v2.0/token/",
[Headers=[#"Content-Type"="application/x-www-form-urlencoded"], Content=Text.ToBinary(body)])),
access_token = Data[access_token]
in
access_token
Then add this token as a parameter into data source code. You may refer to below video to learn more details.
