These are from January so I'm not sure if that's the case anymore:
"**I guess the triggers are still limited to running code and cannot send messages,** which I knew because it always throws the error "conversationId needed". However, I tried using the triggers to execute code or send a JSON payload, which also needs a conversationId. And even though I provided them correctly (in the same way they work without triggers), I guess we can't use code that requires those with triggers (yet).
If my thoughts are correct, consider adding those limitations to docs also. I think that's what causes the most confusion, bot builders think that cron triggers work for every task."
