Before you use Rest API to get access token, you need to registered a client app in Azure AD. Every portal has its url to get access token. The resource url for Power BI API is "https://analysis.windows.net/powerbi/api". Then you need to add parameter into your code body, like your Client ID( from your app) or your account and password.
Here I will show you two ways to get Power BI access token.
1. Get access token by Postman.
For reference: Solved: Power BI REST API using postman - generate embed t... - Microsoft Power BI Community
2. Try this code to get access token in visual studio by C#.
For reference: Get an authentication access token
using System;
using Microsoft.IdentityModel.Clients.ActiveDirectory;
namespace walkthrough_push_data
{
class Program
{
private static string token = string.Empty;
static void Main(string[] args)
{
//Get an authentication access token
token = GetToken();
}
#region Get an authentication access token
private static async Task<string> GetToken()
{
// TODO: Install-Package Microsoft.IdentityModel.Clients.ActiveDirectory -Version 2.21.301221612
// and add using Microsoft.IdentityModel.Clients.ActiveDirectory
//The client id that Azure AD created when you registered your client app.
string clientID = "{Client_ID}";
//RedirectUri you used when you register your app.
//For a client app, a redirect uri gives Azure AD more details on the application that it will authenticate.
// You can use this redirect uri for your client app
string redirectUri = "https://login.live.com/oauth20_desktop.srf";
//Resource Uri for Power BI API
string resourceUri = "https://analysis.windows.net/powerbi/api";
//OAuth2 authority Uri
string authorityUri = "https://login.microsoftonline.com/common/";
//Get access token:
// To call a Power BI REST operation, create an instance of AuthenticationContext and call AcquireToken
// AuthenticationContext is part of the Active Directory Authentication Library NuGet package
// To install the Active Directory Authentication Library NuGet package in Visual Studio,
// run "Install-Package Microsoft.IdentityModel.Clients.ActiveDirectory" from the nuget Package Manager Console.
// AcquireToken will acquire an Azure access token
// Call AcquireToken to get an Azure token from Azure Active Directory token issuance endpoint
AuthenticationContext authContext = new AuthenticationContext(authorityUri);
var token = authContext.AcquireTokenAsync(resourceUri, clientID, new Uri(redirectUri)).Result.AccessToken;
Console.WriteLine(token);
Console.ReadLine();
return token;
}
#endregion
}
}
