I've submitted a blog article here that should get published in the next day or two.

I used JSONPlaceHolder (https://jsonplaceholder.typicode.com/) as the REST service I'm interacting with.  I do selects and simulate updates against it (using the HTTPClient to manually put together the updates because RESTClient won't have that feature until R3).  I say "simulate" because JSONPlaceHolder doesn't actually update the data, but it acts like it does so you can verify that your client is working correctly.

Hi Ron;

     Unfortunately, not at this time as the ones I used on the Webinar this week either had personal Google keys in them and/or called C# Web API web services built from PB. The C# Web API side of the coin though is a PB 2018 feature that I demoed at the Elevate 2017 conference using a very special prototype version of the PB IDE and not available to the public.

    We are currently talking among ourselves as to how best provide the PB Community with some meaningful examples of what I presented in the webinar that will work in the public domain. Stay tuned, I'll try and update you & community as we resolve this challenge.

Regards ... Chris
