Upgrading from a Previous Version

Upgrading from version 3 or earlier

Version 4 of the Slack Developer Kit for Hubot adapter uses a more recent version of the Slack Developer Kit for Node.js. As a result, there are some syntax changes within Hubot:

  1. Before version 4, would return the name of the room(e.g. general). now returns a room identifier (e.g. C03NM270D). If you need to translate the room id to a room name, you can look it up as shown in Send a message to a different channel.

  2. Version 3 of Slack Developer Kit for Hubot supported attachments by emitting a slack.attachment event. In version 4, you use msg.send, passing an object with an attachments array:

       robot.respond /send attachments/i, (msg) ->
           attachments: [
               text: '*error*: something bad happened'
               fallback: 'error: something bad happened'
               color: 'danger'
               mrkdwn_in: ['text']

Upgrading from version 2 or earlier

Version 3 of the Slack Developer Kit for Hubot requires different server support from previous versions. If you have an existing “hubot” integration set up you’ll need to upgrade it:

  • Go to and create a new hubot integration
  • Run npm install hubot-slack --save to update your code.
  • Test your bot locally using: HUBOT_SLACK_TOKEN=xoxb-1234-5678-91011-00e4dd ./bin/hubot --adapter slack
  • Update your production startup scripts to pass the new HUBOT_SLACK_TOKEN. You can remove the other HUBOT_SLACK_* environment variables if you want.
  • Deploy your new hubot to production.
  • Once you’re happy it works, disable the old hubot integration from
