Slackbot Remote Controls allow you to send messages to any public channel as Slackbot.Alternatively:• 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.By creating a Slackbot integration, you agree to the Slack API Terms of Service.
