Authenticated website in Power BI App

[jhayes0128]

I have an internal website that I am trying to add to a Power BI App using the 'Add a link' when updating the Power BI App. This internal website (Azure Web App) has Azure Entra authentication. When using this webapp normally the redirect/callback urls works fine and the user is logged in, however when using from the Power BI App it just says "Unauthorized". Is there a redirect URL I need to add, or better yet since app.powerbi.com already has the authenticated user can i simply retreive that token in my web app to authenticate?

Hi @jhayes0128 ,

One possible solution is to use the Microsoft Entra application proxy to enable remote access to your web app and integrate it with Power BI. Alternatively, you can try to configure your web app to accept the Power BI app's token as a valid credential, by registering your web app as an Azure AD app and granting it the appropriate permissions to access Power BI APIs. You can also use OAuth to authenticate your web app with Power BI.
For more details on how to do this, you can refer to these articles.
