Unfortunately, it doesn’t seem that twitch send the same messages to chat when the command is issued from a program. As a mod, I don’t see the “x got VIP” in chat, nor does the user get a message that (s)he has been added as a VIP. However, the user does get VIPed and he/she gets the badge.
If you could point me a command or a topic on how to monitor the messages that go to the logs or terminal, I think my problem is solved.
Thanks again for your time and guidance.
