App to sent POST / GET URL

Hi,

Microsoft Flow let me trigger an flow by receiving a https POST or GET request. So it is very simple to build flows that start some action.

Some of those actions are so simple, that I would be able to "hide" them behind a button (Tile 1:1). Unfortunatley the WEB App Tile opens a browser TAB or browses to the URL and is not sending just a POST.

I would like to see a simple WEB POST App.

Regards

Reinhard
