Send SMS with REST using C#

The RestSharp library can be used to make REST requests using C# to send SMS.

REST requirements and resources

REST (REpresentational State Transfer) uses the HTTP protocol (HTTPS) for conveying SMS operations. A REST account can easily be obtained for using the Tyr SMS Gateway. REST uses JSON to carry the parameters that relate to the REST operation that you are performing. The following are required to send SMS with REST:

• REST API Key
  API key for the REST SMS API of the Melrose Labs Tyr SMS Gateway

C# requirements and resources

C# is a programming language and can be used to quickly and easily add SMS support for programmatically sending and receiving SMS messages. Use it for transactional messaging and notifications between your application and mobiles. The following are required to send SMS using C#:

• C#
  C# programming language for the .NET platform

Requirements and resources

The following are required to send SMS with REST using C#:

• RestSharp
  REST API client library for .NET

Code

The following example C# code makes a REST HTTPS call to the Melrose Labs SMS API endpoint to send the message Hello World €£$ to mobile number 447712345678 from MelroseLabs. The transaction ID for the message is returned by the endpoint after a successful submission.

using RestSharp;

var client = new RestClient("https://api.melroselabs.com/sms/message");
client.Timeout = -1;

var request = new RestRequest(Method.POST);

request.AddHeader("x-api-key", "[API_KEY]");
request.AddHeader("Content-Type", "application/json");


request.RequestFormat = DataFormat.Json;
request.AddBody(new Item
{
  destination = "447712345678",
  message = "Hello World #$£",
  source = "MelroseLabs"
});

IRestResponse response = client.Execute(request);
Console.WriteLine(response.Content);
