It's possible to integrate Slack with GetBusy for certain actions using Zapier. Check out and subscribe to our Zapier integration idea for further information and updates.
We envisage a future where you will be able to create something new in GetBusy, such as a to-do, from within a Slack channel. You'll be able to create something from scratch or based upon an existing Slack message and be selective about the GetBusy participants (members of the channel, sender of the message etc).
We also plan on being able to push GetBusy activity and/or notifications to Slack.
We haven't started actively working on this yet, but we appreciate the priority for some of you, and having it near the top of the list in terms of votes will keep it our priority conversations.
