Send chat message as channel broadcaster

I know that there is a specific scope for this but how would I do this exactly?
I.e my bots !purge command cannot timeout moderators because he is obviously not the channel owner.

Hang on… You want to send a channel message as a broadcaster automatically?

Why not set-up a message response…? I mean, you got the timeout(s) working.

You will need to obtain a chat_login token for the broadcaster’s account and then run the bot via IRC through the broadcaster’s account.

George, do I need the user’s password or will the received token be enough?

The token is the password you provide to IRC. See for more details.
