Slack Enterprise Grid and BotKit

I have the pleasure of using Slack Enterprise Grid on a daily basis as IBM has adopted it internally, I work there, and there are far too many of us to use a single slack instance. The main downside of Slack Enterprise Grid (apart from having about 15 slack organisations running in your client all the time) is that it returns different data when integrating with the Slack Web API and RTM (Real Time Messaging) systems. We had some bot integration that stopped working as a result, and I ended up moving to BotKit and then using a mixture of the RTM and Web API from Slack to get things to work. I won't remember how I did it so I thought I'd better write it down. Continue reading

Hubot and Slack

I'm enjoying using hubot to integrate services very easily and both give updates and respond to commands in chat. One of my hubots chats to us in slack rather than in IRC, and there are a couple of gotchas that I wish I'd known about before I started!

  • Hubot will not respond to you in PM, you need to join a channel and then /invite @hubot and your bot will join you in that channel and then respond when you address him/her by name
  • When configuring channel names for slack (I use the gitlab plugin which needs a GITLAB_CHANNEL environment variable), do NOT include a # at the start of it if you use slack - works a treat in IRC, but skip it for slack. I spent quite a while looking for a bug in the slack adapter before I figured this one out so it's written here for me to look up next time!
  • Also note that your hubot can only speak in channels that it has joined; I have seen hubot actually crash when asked to speak in a channel that exists but which isn't known to it.

I think this central way of having plugins which can integrate with many messaging platforms on one side, and integrate with many external APIs on the other means we'll be doing much more in chat ops moving forward. Already I'm impressed by how many of the hosted tools I use have webhooks, although there aren't hubot plugins for all of them (yet!).
