Slack Connect: Manage channel invitation settings and permissions

Slack Connect allows members of your organisation to work with people from external organisations in the same channel. Keep reading to learn more about the types of invitations that your organisation can send and the permissions that they grant to external people working in your channels.

Invitation types and permissions

You can decide what type of invitation your members can send when they’d like to collaborate with external people in your organisation’s channels. There are two invitation types that you can manage: Permission only to post and Permission to post, invite and more. The invitation types determine what permissions external people will have in the channels that they’re invited to.

Note: Once the invitation has been accepted, anyone with permission to send Slack Connect invitations can adjust the existing permissions for the external people.
