Get data from the Intune Data Warehouse API with a REST client

  • Raksts

You can access the Intune Data Warehouse data model through RESTful endpoints. To gain access to your data, your client must authorize with Microsoft Entra ID using OAuth 2.0. To enable access, first set up a native app in Azure and grant permissions to the Microsoft Intune API. Your local client gets authorization, and then the client can communicate with the Data Warehouse endpoints through the native app.

The steps to set up a client to get data from the Data Warehouse API require you to:

  1. Create a client app as a native app in Azure
  2. Grant the client app access to the Microsoft Intune API
  3. Create a local REST client to get the data

Use the following steps to learn how to authorize and access the API with a REST client. First, you will look at using a generic REST client using Postman. Postman is a commonly used tool troubleshooting and developing REST clients to work with APIs. For more information about Postman, see the Postman site. Then you can look at a C# code sample. The sample provides an example for authorizing a client and getting data from the API.

Create a client app as a native app in Azure

Create a native app in Azure. This native app is the client app. The client running on your local machine references the Intune Data Warehouse API when the local client requests credentials.

  1. Sign in to the Microsoft Entra admin center.
  2. Choose Microsoft Entra ID > App Registrations to open the App registrations pane.
  3. Select New app registration.
  4. Type the app details.
    1. Type a friendly name, such as 'Intune Data Warehouse Client' for the Name.
    2. Select Accounts in this organizational directory only (Microsoft only - Single tenant) for the Supported account types.
    3. Type a URL for the Redirect URI. The Redirect URI will depend on the specific scenario, however if you plan on using Postman, type https://www.getpostman.com/oauth2/callback. You will use the callback for client authentication step when authenticating to Microsoft Entra ID.
  5. Select Register.
  6. Note the Application (client) ID of this app. You will use the ID in the next section.

Grant the client app access to the Microsoft Intune API

You now have an app defined in Azure. Grant access from the native app to the Microsoft Intune API.

  1. Sign in to the Microsoft Entra admin center.
  2. Choose Microsoft Entra ID > App Registrations to open the App registrations pane.
  3. Select the app that you need to grant access. You named the app something such as Intune Data Warehouse Client.
  4. Select API permissions > Add a permission.
  5. Find and select the Intune API. It is named Microsoft Intune API.
  6. Select Delegated Permissions box and click the Get data warehouse information from Microsoft Intune box.
  7. Click Add permissions.
  8. Optionally, Select Grant admin consent for Microsoft in the Configured permissions pane, then select Yes. This will grant access to all accounts in the current directory. This will prevent the consent dialog box from appearing for every user in the tenant. For more information, see Integrating applications with Microsoft Entra ID.
  9. Select Certificates & secrets > + New client secret and generate a new secret. Make sure to copy it some place safe because you won't be able to access it again.

Get data from the Microsoft Intune API with Postman

You can work with the Intune Data Warehouse API with a generic REST client such as Postman. Postman can provide insight into the features of the API, the underlying OData data model, and troubleshoot your connection to the API resources. In this section, you can find information about generating an Auth2.0 token for your local client. The client will need the token to authenticate with Microsoft Entra ID and access the API resources.

Information you will need to make the call

You need the following information to make a REST call using Postman:

Attribute Description Example
Callback URL Set this as the callback URL in your app settings page. https://www.getpostman.com/oauth2/callback
Token Name A string used to pass the credentials to the Azure app. The process generates your token so you can make a call to the Data Warehouse API. Bearer
Auth URL This is the URL used to authenticate. https://login.microsoftonline.com/common/oauth2/authorize?resource=https://api.manage.microsoft.com/
Access Token URL This is the URL used to grant the token. https://login.microsoftonline.com/common/oauth2/token
Client ID You created, and noted this when creating the native app in Azure. 4184c61a-e324-4f51-83d7-022b6a81b991
Client Secret You created, and noted this when creating the native app in Azure. Ksml3dhDJs+jfK1f8Mwc8
Scope (Optional) You can leave the field blank.

NOTE: Some SDKs, such as the Microsoft Authentication Library (MSAL) for Python, may need the scope defined with double slashes (//).

 SCOPE = ['https://api.manage.microsoft.com//.default']
Grant Type The token is an authorization code. Authorization code

OData endpoint

You also need the endpoint. To get your Data Warehouse endpoint, you will need the custom feed URL. You can get the OData endpoint from the Data Warehouse pane.

  1. Sign in to the Microsoft Intune admin center.
  2. Open the Data Warehouse pane by selecting Reports > Data warehouse.
  3. Copy the custom feed url under OData feed for reporting service. It should look something like: https://fef.tenant.manage.microsoft.com/ReportingService/DataWarehouseFEService?api-version=v1.0

The endpoint follows the following format: https://fef.{yourtenant}.manage.microsoft.com/ReportingService/DataWarehouseFEService/{entity}?api-version={verson-number}

For example, the dates entity looks like: https://fef.tenant.manage.microsoft.com/ReportingService/DataWarehouseFEService/dates?api-version=v1.0

For more information, see Intune Data Warehouse API endpoint.

Make the REST call

To get a new access token for Postman, you must add the Microsoft Entra authorization URL, add your Client ID, and Client Secret. Postman will load the authorization page where you will type your credentials.

Before you make the call, verify that you have already added the Callback URL to your app in Azure. The Callback URL is https://www.getpostman.com/oauth2/callback.

Add the information used to request the token

  1. Download Postman if you do not already have it installed. To download Postman, see www.getpostman.com.

  2. Open Postman. Choose the HTTP operation GET.

  3. Paste the endpoint URL into the address. It should look something like:

    https://fef.tenant.manage.microsoft.com/ReportingService/DataWarehouseFEService/dates?api-version=v1.0

  4. Choose the Authorization tab, and select OAuth 2.0 from the Type list.

  5. Scroll down to the Configure New Token section.

  6. Type Bearer for the Token Name.

  7. Select Authorization Code as the Grant Type.

  8. Add the Callback URL. The callback URL is https://www.getpostman.com/oauth2/callback.

  9. Add the Auth URL. It should look something like:

    https://login.microsoftonline.com/common/oauth2/authorize?resource=https://api.manage.microsoft.com/

  10. Add the Access Token URL. It should look something like:

    https://login.microsoftonline.com/common/oauth2/token

  11. Add the Client ID from the native app that you created in Azure and named Intune Data Warehouse Client. It should look something like:

    88C8527B-59CB-4679-A9C8-324941748BB4

  12. Add the Client Secret you generated from within the native app that you created in Azure. It should look something like:

    Ksml3dhDJs+jfK1f8Mwc8

  13. Select Get New Access Token.

    Information for the access token.

  14. Type your credentials in the Active AD authorization page. The list of tokens in Postman now contains the token named Bearer.

  15. Select Use Token. The list of headers contains the new key value of Authorization and the value Bearer <your-authorization-token>.

Send the call to the endpoint using Postman

  1. Select Send.

  2. The return data appears in the Postman response body.

    Postman client status equals 200 OK.

Create a REST client (C#) to get data from the Intune Data Warehouse

The following sample contains a simple REST client. The code uses the httpClient class from the .NET library. Once the client gains credentials to Microsoft Entra ID, the client constructs a GET REST call to retrieve the dates entity from the Data Warehouse API.

Note

You can access the following code sample on GitHub. Refer to the GitHub repo for the latest changes and updates to the sample.

  1. Open Microsoft Visual Studio.

  2. Choose File > New Project. Expand Visual C#, and choose Console App (.NET Framework).

  3. Name the project IntuneDataWarehouseSamples, browse to where you would like to save the project, and then select OK.

  4. Right-click the name of the solution in the Solution Explorer, and then select Manage NuGet Packages for Solution. Select Browse, and then type Microsoft.Identity.Client in the search box.

    Note

    You must use the Microsoft Authentication Library (MSAL). For more information, see Update your applications to use Microsoft Authentication Library (MSAL) and Microsoft Graph API.

  5. Choose the package, select the IntuneDataWarehouseSamples project under Manage Packages for Your Solution, and then select Install.

  6. Select I Accept to accept the NuGet package license.

  7. Open Program.cs from the Solution Explorer.

    Program.cs and Solution Explorer in Visual Studio.

  8. Replace the code in Program.cs with the following code:

    namespace IntuneDataWarehouseSamples
{
using System;
using System.Net.Http;
using System.Net.Http.Headers;
using Microsoft.Identity.Client;

class Program
{
 static void Main(string[] args)
{
/**
* TODO: Replace the below values with your own.
* emailAddress - The email address of the user that you will authenticate as.
*
* password  - The password for the above email address.
*    This is inline only for simplicity in this sample. We do not
*    recommend storing passwords in plaintext.
*
* applicationId - The application ID of the native app that was created in AAD.
*
* warehouseUrl   - The data warehouse URL for your tenant. This can be found in
*      the Microsoft Intune admin center.
*
* collectionName - The name of the warehouse entity collection you would like to
*      access.
*/
var emailAddress = "intuneadmin@yourcompany.com";
var password = "password_of(intuneadmin@yourcompany.com)";
var applicationId = "<Application ID>";
var warehouseUrl = "https://fef.{yourinfo}.manage.microsoft.com/ReportingService/DataWarehouseFEService?api-version=v1.0";
var collectionName = "dates";

var msalContext = new AuthenticationContext("https://login.windows.net/common/oauth2/token");
AuthenticationResult authResult = msalContext.AcquireTokenAsync(
resource: "https://api.manage.microsoft.com/",
clientId: applicationId,
userCredential: new UserPasswordCredential(emailAddress, password)).Result;

var httpClient = new HttpClient();
httpClient.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", authResult.AccessToken);

var uriBuilder = new UriBuilder(warehouseUrl);
uriBuilder.Path += "/" + collectionName;

HttpResponseMessage response = httpClient.GetAsync(uriBuilder.Uri).Result;

Console.Write(response.Content.ReadAsStringAsync().Result);
Console.ReadKey();
}
}
}

  9. Update the TODOs in the code sample.

  10. Press Ctrl + F5 to build and execute the Intune.DataWarehouseAPIClient client in Debug mode.
