How to do GET request with parameters in UWP?

Question

using Flurl.Http;
dataMapperSurvey = "url"
var responseJString = await dataMapperSurvey.WithHeader("AUTH_TOKEN", "335351").GetStringAsync();

Here I'm try to hit the url with that specific Auth_token porvided in header.

If I check the response in Postman with POST I get an exception and If I do GET I get proper Response.

I don't know how to do GET request here, Can anyone Help?

That looks correct to me. Is it throwing an exception? If so please post those details. — Todd Menier, Dec 04 '15 at 14:13
It's Server side error with code - 500, which comes only when I POST, and all works well when I do a GET. — Hemant-Webo, Dec 06 '15 at 03:58
I assure you your code sample is doing a GET, not a POST. 500 can mean lots of things. Is the server-side code yours or a 3rd-party API? — Todd Menier, Dec 06 '15 at 15:03
It's mine, but it works when I check it through Postman with a GET request. — Hemant-Webo, Dec 07 '15 at 05:35
Sorry, just getting back to this. Is the server app .NET, such as Web API or MVC? — Todd Menier, Dec 10 '15 at 21:25

You've stated that you are receiving a 500 response (usually akin to an unhandled exception) from your own code on the server. This is where you should be focusing your debugging efforts, not on the client side. Assuming you web app is some flavor of ASP.NET that you can run locally in Visual Studio, here's how I'd approach it:

Debug your web app. Either put a breakpoint in the controller or break on all unhandled exceptions.
Investigate the exception details when you call the API with Flurl. Handle the exception and return a 400 (bad request) or something more appropriate, or if it's NOT a bad request, fix the code to handle it correctly.
If it's still unclear why Flurl call behaves differently than Postman, inspect the request from the server (headers, body, etc) and determine what's different.
