Power Bi Embedded Not working Can t login with Master User

Question

Good day to all of you. I have a problem with probably not fully understanding how to embed PBI report in my Xamarin app.  I got my access token and I used Master User for this, but after i GET EmbedUrl and put it in Source proprety of WebView, i get a message: "Please sing in to view this report". This is a problem because my customers don't have PowerBi account and I want them to be able to see this report. Problem might be in my headers I use to get access token, so below is code I use

string url = "https://login.microsoftonline.com/" + tennant_id + "/oauth2/token"; //url to which I POST to

IEnumerable<KeyValuePair<string, string>> parameters = new List<KeyValuePair<string, string>>()
{
new KeyValuePair<string, string>("authenticationType", "MasterUser"),
new KeyValuePair<string, string>("name", "<name>"),
new KeyValuePair<string, string>("workspaceId", "<workspaceId>"),
new KeyValuePair<string, string>("grant_type", "password"),
new KeyValuePair<string, string>("scope", "https://analysis.windows.net/powerbi/api/.default"),
new KeyValuePair<string, string>("resource", "https://analysis.windows.net/powerbi/api"),
new KeyValuePair<string, string>("authorityUrl", "https://login.microsoftonline.com/organizations/"),
new KeyValuePair<string, string>("urlPowerBiServiceApiRoot", "https://api.powerbi.com/"),
new KeyValuePair<string, string>("client_id", "<clientID>"),
new KeyValuePair<string, string>("username", "<username>"),
new KeyValuePair<string, string>("password", "<password>"),
new KeyValuePair<string, string>("client_secret", "<clientSecret>")
};

 After I get access token, I use it in GET request to 

https://api.powerbi.com/v1.0/myorg/reports/<report_it>

 and I pass AuthenticationHeader as 

client.DefaultRequestHeaders.Authorization = new System.Net.Http.Headers.AuthenticationHeaderValue("Bearer", accessToken);

Then I get my embed url which I use in WebView Source property but I am not logged in. When I do login i see this report, but otherwise I can't. Where am I making a mistake/mistakes? I'm new to PowerBi embedding so please explain it like you would to a child.

I figured it out, and I'll put the solution here in case anyone else runs into this in the future. I had to use the JavaScript SDK, and while some of the information there is no longer relevant, it was an excellent resource. Anyway, let's start from the beginning: I had to include WebView in the xaml file as follows:

x:Name="WVtest" HeightRequest="300" WidthRequest="50" Navigated="WVtest Navigated"> x:Name="WVtest" HeightRequest="300" WidthRequest="50" Navigated="WVtest Navigated"> x:Name="WVtest" HeightRequest="300"

</WebView>
Then I tried adding files from the JavaScript API, but I couldn't get them to function (because the documentation was too difficult), so I made some tweaks and used files from my github repo. These files are required in order to view your PBI Embedded report via the embed url.

After that, I added the following code to the function Object() { [native code] } code behind:

"file:/android asset/html/index.html" is the source of WVtest.Source.

This is done so that WebView knows to use the index.html file as its source. It will load this.html and its.js files in order to run the PBI client and display the PBI report.

All REST APIs to PowerBI and Azure are called in the "Navigated" event. To obtain my access token, I send a POST request. This is the URL where I send my POST request:

string url = "https://login.microsoftonline.com/" + tennant + "/oauth2/token"; string url = "https://login.microsoftonline.com/oauth2/token"; string url = "https://login.microsoftonline.com/

tennant is the tennant for your apps.
