Sending Values in an HTTP POST to IFTTT

Does anyone know how to include values in an HTTP POST to IFTTT? I’ve used these in the past to send heating set points to my thermostats controlled through IFTTT. IFTTT does receive the Event, but no matter what method I use, it doesn’t seem to be receiving the Value1.

I’ve tried including these in the JSON body:

{ “value1” : “70”, “value2” : “”, “value3” : “” }

{“value1”:“70”}

I’ve also tried including this at the end if the URL after the key:

?value1=70

The value just shows up as none on the IFTTT side.

Any ideas?
