Hi Team
I have this new URL and want to read all my fields channels, i have created today. My arduino does receieves messages currently, but i am unable to read non of them. What could the reason? Must it be a day to get data to be read? Output is -1 Rest Client response bad request.

Your URL looks good, but you need to set your channel to be public by selecting "Share channel view with everyone" under Channels -> My Channels -> Charing.
Or you can leave your channel private and do as Hans suggests below.

Hi. You are close. You also need to provide a Read API Key.
https://api.thingspeak.com/channels/929272/feeds.xml?results=4&api_key=XXX
Look under the API Keys tab of your channel.
