Here's a simple echo example, written as a Java Servlet in Scala:

class EchoServlet extends HttpServlet {
    
    override def doPost(req:HttpServletRequest, resp:HttpServletResponse) {
   
        // Extract details sent from Taykt to this web hook:
        val from = req.getParameter("pid")
        val mo_msg = req.getParameter("text")
  
        // Compose and send the response:
        resp.setContentType("text/plain")
        resp.setCharacterEncoding("utf-8");
        resp.getWriter().println( from + " sent " + mo_msg  )
    }
  
}

You can try this particular service out with the web hook URL of:

http://taykt-demo.appspot.com/echo

Example call to the web hook:

$ curl http://taykt-demo.appspot.com/echo -X POST -d text="this is my message" -d pid="abc123"

...which produces:

abc123 sent this is my message

We also provide a second example which texts back the time in a given location:

$ curl http://taykt-demo.appspot.com/date -X POST -d text="demodate Sydney" It's 2009-09-17 06:30 in Eastern Standard Time (New South Wales)
