Enable service principal authentication for admin APIs

This article shows how to enable service principal authentication for two types of Microsoft Fabric APIs, read-only and update.

Service principal is an authentication method that can be used to let a Microsoft Entra application access Microsoft Fabric content and APIs.

When you create a Microsoft Entra app, a service principal object is created. The service principal object, also known simply as the service principal, allows Microsoft Entra ID to authenticate your app. Once authenticated, the app can access Microsoft Entra tenant resources.

Method

To enable service principal authentication for Fabric APIs, follow these steps:

1. Create a Microsoft Entra app. You can skip this step if you already have a Microsoft Entra app you want to use. Take note of the app ID which you'll need in later steps.

   Make sure the app you use doesn't have any admin-consent required permissions for Fabric set on it in the Azure portal. See how to check whether your app has any such permissions.

2. Create a new Microsoft Entra Security Group and make sure to select Security as the Group type. You can skip this step if you already have a Microsoft Entra security group you'd like to use.

3. Add your app ID as a member of the security group you created. To do so:

   1. Navigate to Azure portal > Microsoft Entra ID > Groups, and choose the security group you created in Step 2.
   2. Select Add Members.

4. Enable the Fabric admin settings:

   1. Sign in to the Fabric admin portal. You need to be a Fabric admin to see the tenant settings page.
   2. Under Admin API settings, select the switch for the type of admin APIs you want to enable:
      • Service principals can access read-only admin APIs
      • Service principals can access admin APIs used for update

5. Set the toggle to Enabled.

6. Select the Specific security groups radio button and in the text field that appears below it, add the security group you created in Step 2.

7. Select Apply.

How to check if your app has admin-consent required permissions

An app using service principal authentication that calls read-only admin APIs must not have any admin-consent required permissions for Power BI set on it in the Azure portal. To check the assigned permissions:

1. Sign into the Azure portal.

2. Select Microsoft Entra ID, then Enterprise applications.

3. Select the application you want to grant access to Power BI.

4. Select Permissions. There must be no admin-consent required permissions of type Application registered for the app.

Considerations and limitations

• The service principal can make rest API calls, but you can't open Fabric with service principal credentials.

• Fabric admin rights are required to enable service principal in the Admin API settings in the Fabric admin portal.
