How to use Power BI Rest API without GUI authentication (redirect uri)

After executing the above code by replacing the values for ClientID,ClientSecret and TenantId, I am seeing the below error :

Message: The remote server returned an error: (400) Bad Request.

Status: ProtocolError.

I have also tried using the authority uri as https://login.microsoftonline.com/<TenantID>/oauth2/token but still the same error.

I really appreciate your response why I am seeing this bad request error.

Hi,

I am bit confused as to where I can call this code for test. I am new to C#  and it may be the reason for confusion. However I went thru some sample codes in sample application embed-a-tile-into-an-app (Github -dvana/PowerBI-CSharp) etc..  Any chance you could explain some dtails on how to use this code etc..

Regards,

Vish.

Hi there,

What do you use for the Username/Password for your solution.  

We use SSO at our company so not sure what account I can use.

Hi there,
I'm using the same flow as you mentioned here but I'm always getting error at that part.

If I use client credentials such as client_id then I get one token without any user consent dialog . (As long as I develop native java application I cant open a browser to pop it up.) Unfortunately I cant use this token to make a rest api call because I always get 403 forbidden. I understand that authentication for rest api calls should be user specific for Power Bi. So I use this example same as in the adal4f implementation and also with the post man rest tool.  I encounter same error in both as you see in the pictures.

 private static void getPasswordCredentinal() throws IOException {
        HttpPost signIn = new HttpPost("https://login.windows.net/{mytenant}/oauth2/token");

        List<NameValuePair> nvps = new ArrayList<>();
        nvps.add(new BasicNameValuePair("grant_type","password"));
        nvps.add(new BasicNameValuePair("client_id","myId"));
        nvps.add(new BasicNameValuePair("resource","https://analysis.windows.net/powerbi/api"));
        nvps.add(new BasicNameValuePair("username","myuser"));
        nvps.add(new BasicNameValuePair("password","mypass"));
        nvps.add(new BasicNameValuePair("scope","openid")); //optinal
        signIn.setEntity(new UrlEncodedFormEntity(nvps));

        CloseableHttpClient client = HttpClients.custom().build();
        HttpResponse response = client.execute(signIn);
        System.out.println(response.getStatusLine().toString()+" "+response.getStatusLine().getReasonPhrase()+" "+response.getStatusLine().toString());
        String s = EntityUtils.toString(response.getEntity());
        JSONObject jsonObject=new JSONObject(s);
        accessToken = (String) jsonObject.opt("access_token");
        System.out.println(" json object >"+jsonObject);
      

    }

Both produce the same result.

So is there anyting I'm missing? Or is there any way to bypass this consent process programmatically?
Thanks for your help

Can you please clarify what is the TenantId in the above code represents?

That's very useful. However, when registering the application, what values did you use for the redirect URL? It appears to be a mandatory field but in this case, it is not being used

Hi vijaybkodare I have tried this using Postman and I'm getting the following error:
