Hi Team
I have configured using the URL link for email notification below, basically i want to get a notification from email if there is an alert about my channel fields. Question is do i have to change all the default setting when using Matlab analysis as per my own channelID, api key, field names etc?
Error using webwrite (line 130)
Expected URL to be nonempty.
Error in Trigger Email from IFTTT 1 (line 41)
webwrite(iftttURL,'value1',lastValue,'value2',

Is your channel private? If so, then you need to supply a Read API Key with the URL.
url=strcat('https://api.thingspeak.com/channels/',string(channelID),'/fields/1/last.txt?api_key=XXX');
