Create shared channels

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

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

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

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 organisations:

  • On the Standard and Plus subscriptions, only workspace owners and workspace admins can approve requests to share a channel by default.
  • On the Enterprise Grid subscription, only org owners and org admins can approve requests to share a channel by default.
  • Org owners/admins on the Enterprise Grid subscription and workspace owners/admins on the Standard and Plus subscriptions can give others permission to approve requests to share a channel.

Create a shared channel

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

Things to keep in mind

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

Send a shared channel invitation

Before you get started, you’ll need the contact information of someone from the other organisation, such as an email address, phone number or any communication platform you prefer. You can then send a shared channel invitation link to another organisation the way you’d share any link.

Create a new channel

Share an existing channel

  1. Click the  plus icon next to Channels in the left sidebar. For more details, see Create a channel.
  2. Next to the link, click Copy, then Finished.
  3. Using the contact information you have, share the invitation link outside of Slack. You can share this with one or multiple members of another organisation. 
  1. From your desktop, open the channel you'd like to share.
  2. Click the  cog icon to open the Channel settings menu.
  3. Select Add people to channel.
  4. Click Share this channel.
  5. Next to the link, click Copy, then Finished.
  6. Using the contact information you have, share the invitation link outside of Slack. You can share this with one or multiple members of another organisation.

Note: Shared channel invitations expire after seven days. If an invitation link expires before it’s accepted or approved, you can copy a new invitation link to share.

Accept a shared channel invitation

When you receive a shared channel invitation link from a member of another organisation, you or anyone else in your workspace who’s 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 want 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 organisation.
  5. Click Accept invitation.

Tip: The same shared channel invitation link can be sent to multiple people. Only one member of your organisation needs to accept the invitation link before it’s pending approval.

Approve or decline a request to share a channel

When someone in your organisation accepts a shared channel invitation, a request will be sent to both organisations 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 organisation to learn how.
