Last week I was playing with the very cool Rest Getting Started Sample (written in C#). I morphed it into a big loop that deleted all the rows in the dataset, and sent a row with a random value from 1-10. The reason I did this was to try out the new Flow integration with Alerts so I could demo sending emails to groups of people as a result of an alert.
I tweeted about this demo, and had a bunch of private requests from people hoping for a sample of updating data in Power BI directly from PowerApps. This blog post will show you how to insert data into a Power BI dataset from Microsoft Flow.
