Invite external organizations to share a channel

With Slack Connect, you can invite external partners to share a channel in Slack, allowing you to collaborate from your separate workspaces.

There are three steps to sharing a channel:

Note: To share a channel, every participating organization must be using one of Slack’s paid plans. If you're using the free version of Slack, learn how to upgrade your workspace.


Channel ownership

When you invite other organizations to share a channel, your organization will own the channelOnly the organization that owns the channel can do the following:

  • Invite external organizations to share the channel.
  • Remove organizations from the channel.
  • Continue using the channel if it’s no longer shared (the channel will be archived for external organizations).


Invite other organizations to share a channel

You can share a channel from your desktop or mobile device. Keep in mind that invitation links expire after seven days. If an invitation expires before it’s accepted or approved, you can copy a new invitation link to share.

Note: If you'd like to invite additional organizations to a channel shared before June 24, 2020, someone from the invited organization will need to allow the channel to be shared with multiple organizations first.

What's next?

  • Anyone who receives your invitation to share a channel can choose to accept or decline it. For more details on how the invited organization can do this, visit Accept an invitation to share a channel.

  • When someone accepts your invitation to share a channel, it must be approved by someone from your organization with permission to manage shared channels (and possibly also someone from the invited organization, depending on their workspace settings).

Note: In the future, we plan to increase the maximum number of organizations that can share a channel. If your team would benefit from working with more than 19 other organizations, reach out to us — we’d love to learn more!
