Create shared channels

Shared channels let separate organizations work together in a single channel, each from their own Slack workspace. There are three steps to creating a shared channel:

  • An organization sends an invitation link to another organization.
  • The receiving organization chooses to accept or decline the invitation.
  • If accepted, both organizations must approve the request to share the channel.

Note: To share a channel, both workspaces must be on a paid plan. If you're using the free version of Slack, learn how to upgrade your workspace

Things to keep in mind

  • Sharing a channel gives another organization access to only that channel, not everything in your workspace.
  • When you share an existing channel, the other organization can view the channel’s message history, members, and any bots.
  • Members of both organizations can send each other direct messages if they’re a part of the same shared channel.
  • You can share any channel with one other workspace or Enterprise Grid org, except for the #general channel, or multi-workspace and org-wide channels.

Who can create shared channels?

Any member (but not guests) can send or accept an invitation to share a channel. Before a channel is shared, the request must be approved by both organizations.

  • On the Standard and Plus plans, by default, only Workspace Owners and Workspace Admins can approve requests to share a channel.
  • On the Enterprise Grid plan, by default, only Org Owners and Org Admins can approve requests to share a channel.
  • Org Owners/Admins on the Enterprise Grid plan and Workspace Owners/Admins on the Standard and Plus plans can give others permission to approve requests to share a channel.

Shared channel ownership

A shared channel is owned by the organization that creates it. If someone from either organization decides to stop sharing the channel, the owner of the shared channel can continue using it with their team. The other organization will get an archived version of the channel.

Create a shared channel

You can create a brand new channel to share with another organization, or you can share an existing channel.

Send a shared channel invitation

Before you get started, you’ll need the contact information of at least one person from the other organization. You can email an invitation to someone without leaving your workspace, or share an invitation link with as many people as you'd like.

Create a new channel

Share an existing channel

  1. Click the  plus icon next to Channels in the left sidebar.
  2. Select Create a channel.
  3. Enter a channel name and a description, and decide if you’d like to make the channel private. For more details, see Create a channel.
  4. After entering the channel details, click Create.
  5. Click Share this channel.
  6. Enter the email address of the person you’d like to send the invitation to, then click Send. Or click Copy share link to share an invitation link outside of Slack with members of the other organization. 
  1. From your desktop, open the channel you'd like to share.
  2. Click  Details in the top right.
  3. Click Organizations.
  4. Select Share this channel.
  5. Enter the email address of the person you’d like to send the invitation to, then click Send. Or click Copy share link to share an invitation link outside of Slack with members of the other organization.

Keep in mind that invitations expire after seven days. If an invitation link expires before it’s accepted or approved, you can share a new link.

Tip: If you change your mind about a shared channel invitation before it's been accepted, ask an Owner or Admin to write in to us. We'll revoke the invitation for you. 

Accept a shared channel invitation

When you receive a shared channel invitation link from a member of another organization, you or anyone else in your workspace who also received the invitation can accept it. To decline an invitation, you don’t have to take any action. 

  1. Click the invitation link.
  2. Choose the workspace the shared channel will be a part of, or click Sign in to another workspace.
  3. Review and accept the details, then click Accept Invitation.
  4. Choose if you’d like to change the channel name, or make it a public or private channel. Note that these changes will only apply to your workspace and not to the external organization.
  5. Click Accept Invitation.

Approve or decline a request to share a channel

When someone in your organization accepts a shared channel invitation, a request will be sent to both organizations to review and approve. View Manage shared channels to learn how.

Stop sharing a channel

When a project ends, or a channel is simply no longer needed, you can stop sharing it. Visit Stop sharing channels with another organization to learn how.
