Fabric REST API - List Data Pipelines - Unauthorized

[Acroustique]

Hello,

I'm trying to get a list of pipelines using this:

Items - List Data Pipelines - REST API (DataPipeline) | Microsoft Learn

This is the behaviour I have noticed:

Workspace contains pipelines -> Status 200 OK

Workspace does NOT contain pipelines -> Status 401 Unautorized

Surely it should be 200 regardless of the content? Has anyone else noticed this? Is this a known issue?

It turns out I got confused with what the service principal can and cannot access!

I first got a list of workspace ids using:

GET https://api.fabric.microsoft.com/v1/admin/workspaces

Then, I assumed I could get the list of pipelines within those workspaces using: 

GET https://api.fabric.microsoft.com/v1/workspaces/{workspaceId}/dataPipelines  

As it happens, the service principal had access to the workspaces containing pipelines but not the other ones (hence the confusion). 

Now I know that I need to run an admin API call to get all pipelines from all workspaces (regardless of individual workspace permissions), such as:

GET https://api.fabric.microsoft.com/v1/admin/items?type=dataPipeline  

Documentation here:

Thanks! I just wanted to double-check that I wasn't missing something before submitting a support ticket!
