I want to design an API for sending SMS through various websites like way2sms, fullonsms etc.. I tried several APIs like this and also this one 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
http://ultimatesmsapi.tk/sms.php?provider=way2sms&username=9876543210&password=9876543210&numbers=9876543210&msg=your%20msg
and
http://ubaid.tk/sms/sms.aspx?uid=9876543210&pwd=mypassword&msg=myMEssage&phone=9876543210&provider=way2sms
Configured it myself… This thing can be achieved by emulating a web browser.
