I think to create a function that read from a record "To", "Subject", "Text".

Mailgun c# code is this, how can I translate it in Zoho Creator?

2. public static RestResponse SendSimpleMessage() {
3.     RestClient client = new RestClient();
4.     client.BaseUrl = "https://api.mailgun.net/v3";
5.     client.Authenticator =
6.            new HttpBasicAuthenticator("api",
7.                                       "key-bfac6e09124785239032fbae930fdd69c");
8.     RestRequest request = new RestRequest();
9.     request.AddParameter("domain",
10.                         "sandboxf5eeef24d50c45edssf8fce7fb6304c4.mailgun.org", ParameterType.UrlSegment);
11.     request.Resource = "{domain}/messages";
12.     request.AddParameter("from", "Mailgun Sandbox <postmaster@sandboxf5eeef24d50c45edssf8fce7fb6304c4.mailgun.org>");
13.     request.AddParameter("to", "Maurizio <maurizio.blg@cltn.it>");
14.     request.AddParameter("subject", "Hello Maurizio");
15.     request.AddParameter("text", "Congratulations Maurizio, you just sent an email with Mailgun!  You are truly awesome!  You can see a record of this email in your logs: https://mailgun.com/cp/log .  You can send up to 300 emails/day from this sandbox server.  Next, you should add your own domain so you can send 10,000 emails/month for free.");
16.     request.Method = Method.POST;
17.     return client.Execute(request);
18. }
19.
