 * Hey. Hi are you?
   As you received a 404 code, your webhook is invalid.
 * Please, check with Zapier support.

 * Hi Mario,
   On the latest version, it looks invalid because of the error I receive.
   But when I revert the plugin to v3.0.6, it still works.

 * The previous version of the plugin simply didn’t check the webhook response —
   that doesn’t mean it was working correctly before. The new version now verifies
   the response and notifies you in case of failure, ensuring more reliable behavior.
 * _Please note that the webhook might still work even if it returns an incorrect
   status (anything other than 20X), which is not considered a proper implementation
   of webhook._
