Slack Connect: Manage channel invitation settings and permissions

Slack Connect allows members of your organization to work with people from external organizations in the same channel. Keep reading to learn more about the types of invitations your organization can send and the permissions 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 organization’s channels. There are two invitation types 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 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.
