Help Scout connects to Slack through its own Slack app: go to Settings, Apps, Slack Beta, click Install App, allow access, then create notification rules. It sends conversation updates from Help Scout into Slack channels only. You can't create or manage Help Scout conversations from Slack with this integration.
What the connection does for a support team
The Slack integration posts help desk events into the channel of your choice, and it can @mention the person assigned to a conversation with a link straight to it. Notifications can fire when a conversation is created, updated, replied to or closed. For a small team that lives in chat, it means nobody's got to keep the mailbox open in a tab just to notice a new ticket.
The current version is a beta, as of Nov 2026, and it's built around notification rules. Each rule routes a set of inboxes, event types and optional filters to a Slack channel. Several rules can post to the same channel, and one inbox can feed several rules, so you're free to send VIP customers to one channel and billing questions to another.
Before you start: who can install it
- Account Owners, Administrators and any user with the Access API permission can install and configure it.
- It's available on the Standard, Plus and Pro plans.
- You can connect one Slack workspace per account.
You'll also need someone who can approve an app in Slack. If you aren't a Slack admin and your workspace restricts installs, line that person up first.
Setting it up, step by step
- Open Settings (the gear icon), then Apps, then Slack Beta, and click Install App.
- If prompted, log into Slack and click Allow to grant access to your workspace.
- Choose Thread conversations or Unfurl conversations. Threaded mode posts later updates as replies under the original Slack message; standalone mode posts each event separately.
- If you switch on Enable Global mentions, map each help desk user to their Slack user so the right person gets pinged.
- Click the Notifications tab, then New, and set the inbox, the events and the Slack channel for the rule.
- Start a test conversation and check it posts in the channel you chose.
If the channel is private, invite the app or the right people into it first; this guide on adding someone to a Slack channel walks through the menu.
Threaded or unfurled: which to pick
Threading keeps a channel tidy, and that's why it's the default I'd reach for. Every update to a conversation stacks under one Slack message, so the channel reads like a list of tickets and you open the thread to see the history. Unfurled mode is noisier, but each event stands on its own, which suits a low-volume channel where you want every reply to catch the eye.
For most teams, threads in a busy main channel and unfurled posts in a small escalation channel is a sensible split. Rules make that easy, because each one can point at a different channel.
Notifications only, and one workspace
The Help Scout Docs article on connecting Slack is clear about the limits. The integration only sends notifications from the help desk to Slack. Slack isn't a support channel, so you can't reply to customers, create conversations or manage them from Slack. And you can only connect one Slack workspace per account, so if you run a separate workspace for a client, that one stays unconnected.
HIPAA accounts have an extra condition: link unfurling is switched off by default and limited if you turn it on, so expect plainer posts there.
Moving off the older Slack app
If you already used the previous Slack integration, it keeps working. You can install the beta alongside it, build your rules, check they fire, and then remove the old app. That's the safe order, because nothing goes quiet while you're switching over and you won't miss a ticket.

My advice for a two or three person team
Install the beta, turn on threading, and don't overbuild. Start with one rule: new conversations and customer replies from your main inbox into one channel, with mentions for the assignee. Live with it for a week. Add a second rule only when you notice something that should have reached a different channel, and remove the old app once both rules have fired.
