Fabric API quickstart

Introduction

To work with Fabric APIs, like many other Microsoft services, you first need to get a Microsoft Entra token for Fabric service, then use that token in the authorization header of the API call.

In this quickstart tutorial, you will create a C# console app, which will acquire an AAD token using MSAL.Net library, then use C# HttpClient to call List workspaces API.

Create app registration

To get a Microsoft Entra token, you first need to register an application with Microsoft Entra ID.

To learn more about registering an application and different properties of the application and how it might be applicable to your scenario, see Register an app in the Microsoft identity platform.

In this quickstart tutorial, you will create a public client with redirect URI = http://localhost

1. Sign in to the Microsoft Entra admin center as at least a Cloud Application Administrator.
2. Browse to Applications > App registrations.
3. Click on New registration.
4. Enter a display Name for your application, and add Public client redirect URI http://localhost

5. Click on Register.
6. Copy the Application (client) ID and paste it in a notepad to be used later.

Get token

In this tutorial you will use MSAL.Net to acquire an AAD token for Fabric service with the following scopes: Workspace.ReadWrite.All, Item.ReadWrite.All.

For more information about token acquisition with MSAL.Net to, see Token Acquisition - Microsoft Authentication Library for .NET.

Paste the Application (client) ID you copied earlier and paste it for ClientId variable.

C# code sample for acquiring a Microsoft Entra access token

C#

#region parameters section 
string ClientId = "YourApplicationId"; 
string Authority = "https://login.microsoftonline.com/organizations"; 
string RedirectURI = "http://localhost"; 
#endregion 

#region Acquire a token for Fabric APIs 
// In this sample we acquire a token for Fabric service with the scopes  
// Workspace.ReadWrite.All and Item.ReadWrite.All 
string[] scopes = new string[] { "https://api.fabric.microsoft.com/Workspace.ReadWrite.All https://api.fabric.microsoft.com/Item.ReadWrite.All" }; 

PublicClientApplicationBuilder PublicClientAppBuilder = 
        PublicClientApplicationBuilder.Create(ClientId) 
        .WithAuthority(Authority) 
        .WithRedirectUri(RedirectURI); 

IPublicClientApplication PublicClientApplication = PublicClientAppBuilder.Build(); 

AuthenticationResult result = await PublicClientApplication.AcquireTokenInteractive(scopes) 
        .ExecuteAsync() 
        .ConfigureAwait(false); 

Console.WriteLine(result.AccessToken); 
#endregion 

Call list workspaces API

In this section you will:

1. Create the C# HttpClient with the token we acquired in previous section.
2. Add https://api.fabric.microsoft.com/v1/ as the base URL for the client.
3. Call List workspaces API and Write the response to the console.

C# code sample of creating an http client and calling List Workspaces API

C#

// Create client 
HttpClient client = new HttpClient(); 
client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", result.AccessToken); 
string baseUrl = "https://api.fabric.microsoft.com/v1/"; 
client.BaseAddress = new Uri(baseUrl); 

// Call list workspaces API 
HttpResponseMessage response = await client.GetAsync("workspaces"); 
string responseBody = await response.Content.ReadAsStringAsync(); 
Console.WriteLine(responseBody);
