Webhooks

Triggered when a member joins a community

Triggered when a member joins a community: by joining the Slack workspace, by signing in to the community site or the Studio for the first time, or by being added one at a time by an admin (Admin API, Studio add member, or MCP). Bulk member imports do not trigger it. Each of these is its own event, so a member who is provisioned by a sign-in or added by an admin and later joins the Slack workspace triggers it again with a different joined_via; user.profile_id is stable across them.
