Slack Community Integration Guide

Last updated Jul 2nd, 2024


This article provides detailed instructions for how to integrate your Slack community with Common Room. Connect to Slack to monitor messages, replies, and reactions in both public and private channels.

Setup: public Slack channels

Most Slack workspaces allow admins to install apps, but some workspaces are configured to require workspace owner approval. See Slack's documentation for more details.

  1. Select Slack from the list of signals and click Connect.
  2. Connect Slack: You'll need to be an admin in the Slack community if you want to connect to Common Room. Additionally, you'll either need a paid Slack plan or have fewer than 10 installed applications in your Slack community.
  3. Allow Common Room to access Slack. Our integration will be added to all public channels.
  4. Begin data import: Your data will begin importing, and may take up to a few hours, and we’ll email you when everything’s ready.

Setup: private Slack channels

When you add the Common Room bot to a private channel, it can only read information in that specific channel (not other private channels or DMs that the Slack user may have access to). Follow the guide below to integrate private Slack channels with Common Room.

  1. Open Slack and open a private channel.
  2. Click the channel name at the top of the screen.
  3. Select Integrations, then Add an app.
  4. Click Add next to Common Room.
  5. Import data. This will begin the import process and you'll start to see Activity populating in Common Room within a few minutes.

If you want to stop tracking a private channel, simply remove the Common Room app from the channel. This will disconnect the private channel and no further messages will be imported. If you need to delete any data that you imported from a private channel, please contact us.


The Slack integration with Common Room is available on Essentials, Team, and Enterprise plans. To configure Common Room’s Slack integration, you’ll need to be an admin and have permission to add applications to your Slack workspace.

Technical Details

Contacts and Activity

Common Room's integration with Slack works with any Slack workspace that you own. When you connect a Slack workspace to Common Room we’ll import messages, threaded replies, and reactions from public or private channels. Common Room will create a Contact for every user who's joined your workspace.

Note that although Slack creates users immediately when they're invited, we don't consider them a "real" user until they have joined Slack by accepting that invite. Joined Contacts will be displayed in Common Room as soon as they make their first post in Slack.

Import History

Common Room will import the last 30 days of workspace activity. If you update the configuration, these changes are only forward-looking. If you’d like to import more history than this, get in touch with our sales team.

Data Sync

Common Room will automatically import new Activity within a few minutes of it occurring in your workspace.


Can a user's first name be used to send a bulk message?

No. Slack has deprecated usernames in favor of display names, so usually mentioning their “handle” will mention their real/full name (for example, @John Doe).

Why isn't Common Room visible under integrations in my public channels?

Because we monitor all public channels (existing and newly added channels) by default, Common Room is part of the entire Slack workspace, not each public channel.

Does Common Room sync conversations from private DMs or shared channels?

Common Room does not sync conversations from private DMs into the platform. For shared channels, we support any Slack connect channel that is owned by your organization (none that are connected to your Slack workspace that are owned by someone outside of your organization).

Does joining on Slack get counted as an Activity for the "last active" field?

Yes; a Contact who joined Slack will be represented in the last active as it's a Contact-initiated Activity.

I've integrated Slack, but don't see it as an available signal in my Contacts list.

We only show Slack channels as sub-signals once at least one message (bot messages not included) has been posted in the channel where it was integrated.

Why is my Contact's Slack "join" date incorrect?

Currently, Slack API does not provide us with a Contact’s Slack join date. As a workaround, Common Room uses the Contact's Slack profile's "update" timestamp instead. This is a best-effort estimate, and sometimes it will be correct. We’ve found that a good amount of the time, the time at which the user was last updated was when they joined. But there are instances where that’s not true, and in these cases that field would be incorrect.
