Creating a Custom Power BI App

Hi All,

We would like to create an App (https://powerbi.microsoft.com/en-us/documentation/powerbi-service-what-are-apps/) for our customers who use Power BI Service and do not have a Pro subscriptions.

This App would allow the customer to login to our company's custom application, then call a REST web service to populate their dataset.

For an example of how we'd like our custom app to behave, see the GitHub Service.

How can we go about building a Power BI App to do this?

Thanks!
