Work with external organizations in Slack

Collaborating with outside organizations is now as simple as it is to work with in-house teams. Here’s a quick overview to get your team started.

How it works

Separate organizations can collaborate together in a Slack channel, each from within their own Slack workspace. Members can send direct messages, upload files, use apps and integrations, and start calls—all in a common space.

For the most part, the channel will look and feel like regular channels in Slack, with a few key visuals that indicate the presence of an outside organization.

Benefits

Reach the right people

It’s easy to loop in the right people—both internal and external—and keep everyone on the same page.

Streamline communication

No need to manage and reconcile disparate conversations happening across email, phone calls and meetings. With everything in one place, there’s less context switching. Your team (and theirs) save time.

Share information and context faster

Real-time collaboration means information flows freely between teams, moving work forward. And when new members join a channel, they can access and search the channel’s entire history, getting them up to speed quickly.

Build trust

Develop deeper partnerships with external partners by making communication easier, more direct and more casual. Each side can easily see what’s happening and who’s responsible for what.

 

Thanks to shared channels, everyone can tell us exactly what they want. It’s a real game changer.

Security

Keep your company’s data and information secure while allowing your team to do its best work. Users can share a channel by sending an invitation link to their external partner. Depending on your settings, admins on each side must approve the channel and can disconnect the channel at any time.

Each side can decide if the channel is public or private in their own workspace. Once the channel is created, members can invite colleagues from their respective teams without admin involvement.

Setup

To create a channel with an outside organization, follow the simple steps below.

  • To share an existing channel, click on the channel details icon located at the top right-hand corner of the channel. Then, select “Add” and “Share this channel.” Follow the prompts to share the channel with external partners or companies.
  • To share a brand-new channel, follow the steps outline here.

 

Ready to get started?

These tips will help you get up and running:

  • Review external business partners and ongoing initiatives to identify 3–5 initial use cases.
  • Check the Slack guest account usage in your workspace directory. It might make sense to convert some of your guest accounts to a channel in Slack.
  • With your Slack admins, align on external guidelines for sharing channels in your organization.
  • Reach out to our customer experience team with any questions by typing /feedback in Slack or sending an email to feedback@slack.com.
