ADF Rest API Using Service Principal

[bcdobbs]

Hi,

I'm trying to use a copy data activity in Fabric Data Pipeline to get data from MS Graph API. Just trying to recreate a small pipeline I have working currently in Azure.

It looks like I should be able to connect using a service principal but I can't make it work:

Wondered if anyone had any luck or pointers! Wondered if it was because there's no where to specify the AAD resource like there is when you set up a linked service in Azure:

I get the same if I try https://api.powerbi.com

Hi,

But if we access the documentation link you provided, it mentions service principal as supported capability:

Supported capabilities Gateway Authentication

Copy activity (source/destination)

None

Anonymous Basic Service principal

Still, it doen't work. Can you confirm, is the documentation wrong? 

Thanks!

Thanks for the feedback. Service principal should be supported, but there is issue. Will share update on this.

Hi @GraceGu,

I thought it may have become available. At launch the option wasn't there but earlier this week the following appeared:

Which makes it at least look like it's supported.

You are correct. It should be supported now, but not updated in doc.

Are you able to check your end if they believe it's fully working? (Struggling to make it do what I think should do.)

[GraceGu]

Yes, I am checking

REST connector does not support service principal authentication yet. You can check the auth type supported in connector REST connector overview - Microsoft Fabric | Microsoft Learn.

It is in roadmap. While it will be also helpful if you can submit an idea to prioritize.  

Thanks
