Hi ArjunKrishna,
Basically you want to call power Bi data using UiPath api activities.
So, basically in Power Bi there is an option in upper ribbon Get Data.
Click on → Get data–> A dropdown will open–> then select web option–> after that you can enter details of api in req fields create api’s and then in Ui-Path call that api’s with same parameters and done data will be fetched.
