SharePoint Azure ACS Retiring — What’s the Supported Modern Auth Path for Fabric Pipelines?

Hi AdarshChekodu,

 Thank you for reaching out to the Microsoft Community Forum.

As of today, there is no Fabric native connector that supports SharePoint via Microsoft Graph with Entra ID app only e.g., Sites.Selected. For unattended ingestion, move to an Entra ID app registration preferably certificatembased and call Microsoft Graph directly. In Fabric, that typically means using HTTP activities in pipelines or notebooks (e.g., Python) to acquire a token and read SharePoint data via Graph APIs.

There’s also no publicly confirmed timeline for a Graph based SharePoint connector in Fabric, so you should plan assuming this gap will remain for now. For unattended scenarios, the safe pattern is Graph + Entra ID app-only + certificate auth, orchestrated through Fabric pipelines or notebooks.

There aren’t many official end-to-end Fabric examples yet for Graph + Sites.Selected, so in practice you will need to stitch this together using standard Graph patterns token acquisition + API calls inside pipelines or notebooks.

Hope the above provided information help you resolve the issue, if you have any further concerns or queries, please feel free to reach out to us.
Regards,
