ChatActivity

- ChatActivityResponse — A ChatActivity represents an active conversation thread between a patient and staff in Luma Health's messaging hub, tracking assignment to an individual user or a group, its status such as unassigned, assigned, or closed, and details like the last message sent and any linked facilities. It records why a conversation was closed and flags whether the latest activity resulted from an automated message such as an appointment reminder or from a genuine unexpected reply needing attention. This resource underlies how staff triage, prioritize, and manage incoming patient messages across the organization.
