title: how to design an api for sending sms
body: <p>I want to design an API for sending SMS through various websites like <strong>way2sms, fullonsms</strong> etc.. I tried several APIs like <a href="http://ultimatesmsapi.tk" rel="nofollow">this</a> and also <a href="http://ubaid.tk" rel="nofollow">this one</a> but I am thinking of designing my own because of the traffic on their servers. Any idea about how to start. I am good at coding in C#. The link they currently provide to send sms is like this</p>
  
  <pre><code>http://ultimatesmsapi.tk/sms.php?provider=way2sms&amp;username=9876543210&amp;password=9876543210&amp;numbers=9876543210&amp;msg=your%20msg
  </code></pre>
  
  <p>and </p>
  
  <pre><code>http://ubaid.tk/sms/sms.aspx?uid=9876543210&amp;pwd=mypassword&amp;msg=myMEssage&amp;phone=9876543210&amp;provider=way2sms
  </code></pre>
