HTTP API Code Sample – C#

The code sample below shows you how to send SMS messages quickly using a simple C# snippet based on the HTTP API. The script sends a single 1-way SMS message that will appear to come from "XYZCorp".

Send a 1-Way SMS Using C#

// Import the required libraries
using System.Net;
using System.IO;

// Create a new web client to send the request
WebClient client = New WebClient();

// Add the various parameters that need to go out
// with the HTTP request
client.QueryString.Add("username", "my_username");
client.QueryString.Add("password", "SecrEt12345");
client.QueryString.Add("message", "Hello World");
client.QueryString.Add("type", "1-way");
client.QueryString.Add("senderid", "XYZCorp");
client.QueryString.Add("to", "61400000000");

// Set the URL to send the request to. Please note,
// you can use HTTP or HTTPS
string url = "http://api.directsms.com.au/s3/http

// Send the request and read the response
Stream stream = client.OpenRead(url);
StreamReader reader = New StreamReader(stream);
string response = reader.ReadToEnd();

// Close the data stream and HTTP connection

// The response from the gateway is going to look like
// this:
// id: a4c5ad77ad6faf5aa55f66a
// In the event of an error, it will look like this:
// err: invalid login credentials
