how to connect dataflow with webAPI using Dataflow PowerBI Service

[Anonymous]

Actually I'm beginner with powerBI service, I created DataFlow then filled in needed parameters to consume a WebAPI. My problem is that I'm getting Data from Toggl so its not an on premises Data Source so its supposed to work without an on premises gateway. But in my case if delete the on-premises Getaway and select none it wont work and its raising this error : Invalid credentials. (Session ID: e6a5c147-0f28-4c59-b707-e69851c19, region Europe). Could you please help me to know if the on premises Gateway is required or not as its not on premises data source? Also if not any reference or steps how to get the job done without on premises Gateway would be perfect, thanks a lot

If it's a cloud data source, you don't need a gateway for sure.
