Calling the SetDigitalOutput function for an Arduino microcontroller

Hello,

I am trying to call the SetDigitalOutput function for an Arduino Uno microcontroller that has an Arduino Ethernet shield. I am able to call this function from the Teleduino website. If I have to call the function I use the below URL.

https://us01.proxy.teleduino.org/api/1.0/328.php?k=<key for my Arduino Uno>&r=setDigitalOutput&pin=3&output=1&expire_time=0&save=1

Using the above URL I can set a value of 1 to a digital pin 3 on the microcontroller.

Now, what I am trying to figure out is how I can call the SetDigitalOutput function from the Hana Cloud Platform (hcp) IOT services. In the MMS cockpit when I paste the above URL and paste it as shown below in the screenshot it doesn't do anything to my Arduino

Is there a lot to be done yet? My main concern is that the Teleduino URL appears to be a https Get command while all the MMS messaging technique appear to be sending messages through the Post command.

Comments welcome.

Regards

Bala
