Question

I need to call an API with POST arguments, for example:

• URL = http://localhost/myAPI/
• ARGS = options=blue&type=car

I’ve had a look at XDocument but not sure how to send params in the request. I’m also not sure how I would call asynchronously, and even if I should or if it’s better/easier to run in another thread.

I’d be calling this from my windows based C# application.

You can use one of the Upload methods of WebClient.

WebClient client = new WebClient();
string response = client.UploadString(
                  "http://localhost/myAPI/?options=blue&type=car", 
                  "POST data");
