Hello. I am doing a Thingspeak project and I am having this issue that is printed out on only one of my MATLAB analyses which is: Error using matlab.internal.webservices.HTTPConnector/copyContentToByteArray (line 396) The server returned the status 429 with message "Too Many Requests" in response to the request to URL Error in readContentFromWebService (line 46) byteArray = copyContentToByteArray(connection); Error in webwrite (line 139) [varargout{1:nargout}] = readContentFromWebService(connection, options); Error in High humidity (line 8) result = webwrite(alert_url, jsonmessage, options); Can I know what this issue means? The rest of my analyses do not have an issue -- only one of them does.

Hey there, I want to delete a thingspeak channel using the webwrite function. This is what it looks like: url = ['https://api.thingspeak.com/channels/' channelID '.json'] options = weboptions('RequestMethod','delete', 'MediaType','application/x-www-form-urlencoded'); response = webwrite(url,'api_key',userAPIkey,options) This returns status 401 Unauthorized. But if I only change the RequestMethod to 'put', I don't get any errors. But using 'put' only allows me to change the channel settings. How do I delete the channel using webwrite?
