Why I can't sent emails with Matlab Analysis? (Having error 429).

I have doubt about why I can't receive emails.

I'm uploading data with an ESP8266, and I'm trying to send an email alert when Thingspeak is not receiving any data.

When I run the code, it only shows me a message error with the code 429.

I implemented the following code:

channelID = *********; 
alertApiKey = 'TAK**************';
alertUrl = "https://api.thingspeak.com/alerts/send";
options = weboptions("HeaderFields", ["ThingSpeak-Alerts-API-Key", alertApiKey ]);
alertSubject = sprintf("ALERTA RED FRÍA");
moistureData = thingSpeakRead(channelID,'NumDays',1,'Fields',1);

if isempty(moistureData)
    alertBody = 'No hay datos disponibles. Posible falla en la conexión a internet o falla eléctrica';
end
      try
 
          webwrite(alertUrl , "body", alertBody, "subject", alertSubject, options);

    catch someException
    fprintf("Failed to send alert: %s\n", someException.message);
end

See Error Codes. 429 is too many requests. You can see the limits on the send alert page in the limitations section.

I reccomend using the no data insert condition in react to track your channel.
