Answer 1

Here is the rest endpoint you are looking for:
http://hololens5.northeurope.cloudapp.azure.com/INTERSHOP/rest/WFS/inSPIRED-
inTRONICS_Business-Site/-;loc=en_US;cur=USD/products/1599925

Answer 2

Because
http://hololens5.northeurope.cloudapp.azure.com/INTERSHOP/web/WFS/inSPIRED-inTRONICS_Business-Site/en_US/-/USD/ViewProduct-Start?SKU=1599925&CategoryName=151&CatalogID=Computers
Is webpage and not API endpoint so you need to find proper endpoint from where you want to get data
Once you get Proper Endpoint you can use below
Here is an example how you can use httpclient to make a request
static void Main()
{
Task t = new Task(DownloadPageAsync);
t.Start();
Console.WriteLine("Downloading page...");
Console.ReadLine();
}
static async void DownloadPageAsync()
{
// ... Endpoint
string page = "request URL";
// ... Use HttpClient.
using (HttpClient client = new HttpClient())
using (HttpResponseMessage response = await client.GetAsync(page))
using (HttpContent content = response.Content)
{
// ... Read the string.
string result = await content.ReadAsStringAsync();
Console.WriteLine(result);
}
}
