Hello , can you provide more details on how to setup the Agent parameter with the Thingspeak channel...what part of the code gets substituted..

@sandboard

Issue resolved.
for the future..
fill the "KEY" with the API provided by Thingspeak number this should be a 16 digit number.
"X-THINGSPEAKAPIKEY":"XXXXXXXXXXXXXXXX"}
