Hi,

I am testing sending out email from Matlab Analysis when using ThingSpeak. I can only send one email out. If i want to send it again, i get the erro message "The server returned the status 429 with message "Too Many Requests" in response to the request to URL https://api.thingspeak.com/alerts/send.".

What is the allowed rate at which i can send the emails out?

thanks

See this link for alerts rate:

https://www.mathworks.com/help/thingspeak/sendalert.html

Users are limited to 2 alerts every 30 minutes. The rate limit is applied when the request is made, not when the email is sent. If you exceed the request limit, the API returns the response code 429.

Hey vladimir,

i understand that when you are sending emails from Matlab Analysis by using ThingSpeak, you get the error message :

The server returned the status 429 with message "Too Many Requests".

The HTTP 429 "Too Many Requests" response status code indicates the user has sent too many requests in a given amount of time.

There is currently a limit on read operations on a channel at four times the maximum channel rate limit. For paid licenses, this limits you to four read operations on the channel per second.

I hope this helps!
