Rest API calls with PowerApps
I am playing around with Microsoft PowerApps and Microsoft Flow. I am trying to figure out how to make API calls from PowerApps and return the results(Status and Body) to a field such as a text box in my app.
I can make the HTTP requests through Flow and put them in a static file such as an excel spreadsheet...etc. I can also make the calls from a PowerApps control such as a button but all I know how to do with it is return it to something like an excel file, when really I want to return it to a Text Box or Text Area.

Today you cannot access the raw HTTP status/body from a PowerApp. The way to call "arbitrary" HTTP endpoints is to use Custom APIs that you can describe using Swagger. I wrote a quick blog on how to call Azure functions that shows how to craft a swagger to call the API: https://powerapps.microsoft.com/en-us/blog/using-azure-functions-in-powerapps/
Might be good if you could clarify the specific scenario you are trying to build to see if there are other ways, but one option that comes to mind is to build a custom API that receives the URL and on the server-side performs the HTTP request and returns the values in an object that then you can easily access in PowerApps.
