Power BI Dataset Deployments

Hello,

         Has anyone been able to perform all these steps below using App (Clientid/Secret):

1) Deploy PBIX dataset to power bi service 

2) update dataset parameter

3) Get a list of datasource id from Gateway cluster

4) Bind dataset to specific Gateway ( postman comes back as 'API is not accessible for application' message)

     there are 2 datasources with same server name so need to bind to specific gateway by using datasourceid

Steps 1 and 2 are possible using rest api and by using the App. However, steps 3 and 4 requires doesnt succeed.

   I have already added all delegate permissions to the App, Added the app as member to an azure group that has been provided Power BI Administrator role.

Is the only alternative is to create a dummy/service account -> provide admin access and then use it for deployments?

Thanks

Rakesh
