Unable to trigger fabric data pipeline using REST API's

munnas - The API that you use to trigger a Fabric Data Pipeline does not support Service Principals.  You have to use a named user account & password.  They will be bringing service pricipal support to more API's in the future.

It does work with Username/Password as we are able to do that within our Company.   It will eventually work in Power Automate but since the API does not return a response the HTTP Post with Azure Entra (preauthorized) does not function properly.

There is another thread in the community that goes into more detail.  It's fairly recent.
