Slackbot Remote Controls allow you to send messages to any public channel as Slackbot.
• If you want Slackbot to respond to messages that members of your team send in public channels, you can configure Slackbot Responses.
• If you want a little more control over your automated messages (such as specifying the username or adding formatting), you’ll want to use Incoming WebHooks.
Slackbot is your very own friendly, built-in bot — part-time programmer and full-time assistant — here to help you keep things in order. There are lots of things Slackbot can help you with.
