I want to alert another tool I am using when a user subscribes to a certain list (in this case through a klaviyo sign upform). Is there a way I can do that? Does Klaviyo have a webhook that will trigger on sign up of a form? Or is it best to poll the API to see changes made to a specific list every minute or so? What is recommended here? We are using the klaviyo sign up form and want to tell another platform when a new subscriber signs up.
