KCS http post ifttt/set

[stanchiam]

Hi,

I want to trigger the IFTTT using http post, example http://192.168.1.123/ifttt/set with payload {"cmd":"run","ids":[2]}
But was returned with {"code":-1,"status":"auth failed"}

How to post to trigger the  IFTTT?

Also, can I trigger the digital input using http? PDF only how to use set_output but not input

Thank you.
