Earlier this week I gave a webcast on accessing web services with Power BI, Power Query and M on Reza Rad’s YouTube channel. You can watch it here:
It’s an introduction to the subject: I cover the basics of using Web.Contents but don’t go into all the obscure details of what each of the options for it do (most of which I have blogged about anyway). I hope you find it useful!
I just saw a great webcast about Power BI. It gives a comprehensive overview of Power BI and accessing API and web service data using Power Query.
