C# Xamarin To Query Asp.Net API

Hi friends - I have this syntax that I am attempting to query an API and return data from it. My issue is that when the syntax hits List<IH> ih... line it returns a 500 error. Can someone examine this and let me know what I should do to remedy?

private void LoadGrid()


List<IH> IH = new List<IH>();

IH = [login to view URL](company);

//more code here


public List<IH> GetInfo(string company)


string URI = "XXXXXXXXXXXXXXXXXXXXX/api/InvoicePull";

using (var webClient = new [login to view URL]())


var json = [login to view URL](URI);

List<IH> ih = [login to view URL]<List<IH>>(json);

return ih;
