Announcing Service Principal support for Fabric APIs 

A new way to authenticate and authorize your Fabric applications.

You can now use service principal to access Fabric APIs. Service principal is a security identity that you can create in Entra and assign permissions to it in Entra and other Microsoft services, such as Microsoft Fabric. 

With service principal you can automate your Fabric processes and integrate them with other services. 

Which Fabric APIs support service principal? 

The following Fabric APIs support service principal authentication and authorization: 

  • Fabric Item CORE CRUD APIs for the following item types:
    • Paginated Report

    • Notebook
    • Environment
    • Spark Job Definition
    • EventHouse
    • KQL Database

We are working to enable service principal support for more Fabric APIs, stay tuned for more updates.
