How to send text using c#.net

How to send text using c#.net

To send a text programmatically your code needs to make an XHR request to an SMS gateway that will read the text details from your request and then initiate a text to the recipient’s phone number

PureText offers a Texting/SMS gateway to which you can make an HTTP GET/POST request with details such as recipient number and body of the text and PureText will deliver the text to the recipient for you.

In order to identify that this request belongs to you, you’ll need to include your API token in the HTTP GET/POST request. Register for a free API token here

A thing to note is that you cannot just use any phone number as the ‘From’ number. The rule of thumb is the number must be registered through the same company who’s SMS gateway you choose to use.

To send a text message using C#.net or VB.NET you don’t need a dedicated short code

Dedicated short codes are expensive and take 2-3 months to get approved, instead, you can now use local 10 digit VOIP numbers or also referred to as long codes to send a  text/SMS programmatically from your C#.Net or VB.Net web app or desktop app.

So let’s get started, to do a quick and dirty POC you’ll need:

  1. An API token key  (free API token here)
  2. A ‘From’ number through your SMS gateway (Get a free one here)

 Copy Paste the following code in your IDE and replace the API Token and From Number values with the ones you registered above.

using System;
using System.Collections.Generic;
using System.Net.Http;

public class Program
{
    public static void Main()
    {
        String URI = "https://api.puretext.us/service/sms/send";
        String resultContent;

        using (var client = new HttpClient())
        {
            var values = new Dictionary < string, string > 
                        {
                            // To Number is the number you will be sending the text to
                            { "toNumber", "+X-XXX-XXX-XXXX" },
                            // From number is the number you will buy from your admin dashboard
                            { "fromNumber", "+X-XXX-XXX-XXXX" },
                            //Sign up for an account to get an API Token
                            { "apiToken", "XXXXX" },
                            // Text Content
                            { "smsBody", "SENDING TEXT USING .NET" }

                         };

            var content = new FormUrlEncodedContent(values);
            var result = client.PostAsync(URI, content).Result;
            resultContent = result.Content.ReadAsStringAsync().Result;
        }

        Console.Write(resultContent);
        Console.Read(); //to keep console window open if trying in visual studio
    }
}
