Anonymous — Thu, 02 Nov 2017 06:05:26 GMT

Hi,

I am new to Power BI embeded service.and need some help to configure it.

I have following -

Azure Active Directory tenant which comes with Office 365.
Power BI Pro Account (1 Year free subscription).
Register the native app with local URL http://localhost:42734/ through Power BI App Registration Tool and have the client ID.

I am facing issues to "Access token for non-Power BI users (app owns data)". I am using Power BI Embedded Apps Owns Data sample downloaded through Github.

I have updated the following paramenters in the project file -

client id
group id
pbi username {power bi login mail id}
pbi password {power bi login password}

When i am sunning project it is giving error

From the stacktrace, the error status code is 408, a timeout error, what's going on if you call the below API in POSTMAN?

POST /common/oauth2/token HTTP/1.1
Host: login.windows.net
Cache-Control: no-cache 
Content-Type: application/x-www-form-urlencoded

client_id{your client id}&grant_type=password&resource=https%3A%2F%2Fanalysis.windows.net%2Fpowerbi%2Fapi&username={your pbi account}&password={your pbi passoword}

You can reference Use Postman to test API calls.
