List conversations

Account-wide list of reply conversations (the Replies Inbox) — not scoped to one campaign. This is the list view; for the full message content of one conversation, use Get lead thread under the Campaigns API.

No standalone “get conversation” or “reply” endpoint

The public API doesn't expose a per-conversation fetch or an endpoint to send a reply — only this list and the per-lead thread read under Campaigns → Get lead thread.
