Making http request from code behind

Question

I am trying to implement Message API

I am not sure how I will be calling this from code-behind and in their snippet it says:

https://platform.3cinteractive.com/api/send_message.php 

POST
username=aRDSe3vcaMzh06YrMcxcQw==&password=1BSvQc6lpNlnp4ufWgRLPHNJ7RMrL8CcaWCzL1Vtw+Y=&phone_number=+11234567890&trigger_id=1105&message=howdy

Answer 1

Use the WebRequest class below or use a library like RestSharp for more control or your HTTP request:

// Create a request for the URL.        
WebRequest request = WebRequest.Create ("http://www.contoso.com/default.html");
// If required by the server, set the credentials.
request.Credentials = CredentialCache.DefaultCredentials;
// Get the response.
HttpWebResponse response = (HttpWebResponse)request.GetResponse ();
// Display the status.
Console.WriteLine (response.StatusDescription);
// Get the stream containing content returned by the server.
Stream dataStream = response.GetResponseStream ();
// Open the stream using a StreamReader for easy access.
StreamReader reader = new StreamReader (dataStream);
// Read the content.
string responseFromServer = reader.ReadToEnd ();
// Display the content.
Console.WriteLine (responseFromServer);
// Cleanup the streams and the response.
reader.Close ();
dataStream.Close ();
response.Close ();

You need to use a WebRequest and do an HTTP POST. See this article entitled How to: Send Data Using the WebRequest Class.
